In this study two scoring systems are compared, being the cow comfort score system [20] and the Welfare Quality® assessment protocol for dairy cattle [21]. These scoring systems are developed to score the welfare of dairy cows. The study was performed in the northern part of Greece during February and March 2010 by two investigators combined with another study. A random sample of eight farms were visited, the size of the farms differed from 32 to 175 dairy cows. Because the cow-comfort score is designed for Holstein Friesian cows and has to be applied on stalls with cubicles only farms with this breed and these type off barns were used. The main difference lies in the practical execution. The cow comfort score system is committed more to assess the environment of the cow. The Welfare Quality® protocol gives much attention to individual cows, about their emotional and physical state. The cow comfort score system is more easy and quick to use. Examining cows individually takes longer and is more subjective. Examining the environment of the cow is objective and can be done quickly. Despite the duration difference in execution the results of both systems had a correlation of 0.843 (P= 0.009). Scores achieved by the individual farms using the cow comfort score system varied from 55 until 330 points. The overall assessment of the farms with the welfare quality protocol varied from not classified to enhanced. The results of this study show that both systems can be used to assess the welfare status of the cows on a dairy farm in Greece. Since the number of farms studied in the present study is not large, more studies are needed to confirm the findings. A comparison of two animal welfare protocols for dairy cattle 3 2 Introduction Animal welfare is very important these days. This is partly because consumers are more aware of what they consume. They want transparency of the production of animal products. Animals are supposed to have a good life [22]. Fortunately, cow comfort is also becoming more important for dairy farmers. Nowadays, farmers are more open-minded for changes on behalf of cow comfort, which is a welcome change in this sector. It is well known that if a cow doesn’t feel comfortable with the environment, this can cause stress [5,20,21,22]. The stress causes different behavioural and physiological responses, which may influence the cow’s wellbeing negatively. This can have a negative influence on the animal’s health and fertility and can result in a decrease in milk production [5,20,21]. Therefore, it is of great importance for the farmer to provide his cows good housing- and milking conditions. Major areas of the physical facilities to consider in relation to cow comfort are building and stall design, climate conditions, bedding type, light regime, floor and walk lanes, feeding fence and milking machine characteristics [20,21,22,23]. To know if cows are comfortable with their environment this has to be examined. Cow comfort becomes primarily visible through the body and behavioural language of cows. For example, a sign of reduced lying comfort is cows standing idle or sleeping in walkways. Information about stall design can be collected by close observation of cows standing up and lying down [10]. Poor stall design also accounts for the incidence of physical injuries such as leg and claw problems [9]. Is the cow afraid of human contact? Is the animal tail hanging straight and relaxed? Is the cow bellowing? And so on. In previous studies the above issues are proven to be related to cow comfort [17,19]. Examining a cow gives direct information about the emotional and physical state of the animal. Viewing the environment indicates whether a cow can perform certain behavioural acts or not. Is the animal able to drink, eat, walk, lie down? If a cubicle is not fulfilling the needs, this affects the cow comfort [1]. For example, poor stall design will cause less lying down of the cows. Cows that are standing when they would like to be lying down will get stressed. Moreover, standing costs more energy [17,18]. If cows are not lying down enough, milk production and health performance are at risk. The mammary blood flow is increased during lying with respectively 25%, according to Metcalf et al [12] or 50%, according to Rulquin et al [16], which is positively correlated with milk yield [13,15]. Decreased cow comfort causes stress. Stress will lower the milk production. The influence of the different items on cow comfort, however, varies. Nevertheless, useful information can be collected because many cows in the same circumstances are observed. Certain factors need continuous attention, like temperature and humidity control, stall hygiene, food and water supply [21]; others are continual factors in a stable so they do not need frequent monitoring, like freestall design, facility design and feeding fence [21]. Recently, protocols have been developed to assess the living conditions of the cow [21,23]. These instruments consist of monitoring the body language and behaviour of cows and a scoring of the environment in which the cows are housed. Applying these scoring systems gives an overview of the cow comfort at farm level. It shows what is good and where there is still room for improvement. The objective of this study was to provide an overview of the similarities and differences in content and scope of two protocols for the assessment of animal comfort and well-being in dairy herds: (a) the Cow Comfort Protocol [21] and (b) A comparison of two animal welfare protocols for dairy cattle 4 the Welfare Quality® Assessment Protocol for dairy cattle [23]. To ascertain the practical application of these two protocols on commercial dairies, a survey was designed to compare the rank order of compliance scores of each protocol on 8 commercial dairies using personal observations and interviews with dairy farmers. A comparison of two animal welfare protocols for dairy cattle 5 3 Material and Methods In this study, two different cow comfort scoring systems are applied and compared on eight farms, being the cow comfort score system and the welfare Quality assessment protocol for dairy cattle. The study was performed in the northern part of Greece during February and March 2010 by two investigators combined with another study. A random sample of eight farms were visited, the size of the farms differed from 32 to 175 dairy cows. Before going to Greece, the investigators were trained to apply the system on farms. As the cow-comfort score is designed for Holstein Friesian cows and has to be applied on stalls with cubicles, only farms with this breed and these type off barns were used. The investigators visited and scored the farms at the same time to minimize subjective decisions. For both systems the jobs were split, to work more quick and accurate. The cow comfort score system is developed by Dr. Frank J.C.M. van Eerdenburg, Department of Farm Animal Health, Faculty of Veterinary Medicine Utrecht. Using this system observations are made containing general behaviour of the cow, light, ventilation, cubicles, floor, walkways, feeding fence, water, etc [21]. The second scoring system which was used is the Welfare Quality® assessment protocol for dairy cows. This protocol is developed by ID-Lelystad and partners. Using this system observations are made containing good feeding, good housing, good health and appropriate behaviour [23]. Cow comfort score system The first scoring system used is the cow comfort score system. In this system chapters with various items of interest must be observed. For each item points can be scored [Appendix 1 and 2]. Most points were scored directly by the investigators observations at the animals, but for some points (animal performances, etc) were scored by personal interviews with the farms managers based in a questionnaire [Appendix 3]. The chapters are the following: General This chapter contains items considering the environment at the time of scoring and the cow behaviour. Items scored include environmental noise, bellowing, number of cows standing idle and fear behaviour. An investigator counted the number of cows standing idle and listened for the environmental noise and bellowing. For the other items the cows were closely observed. Light Items scored are sufficient light in the barn, period of light and period of dark. The period of light and darkness were questioned to the farmer, while the sufficiency of light was judged by an investigator. Ventilation Items scored for this chapter consider the ventilation and climate in the barn. Because of the presence of open barns in Greece, the use of a smoke machine to test the ventilation was not necessary. Cubicles / Free stalls Checking the cubicles consisted of size (for this a tapeline was used), lunge space, neck rail, brisket board, number and bedding. Bedding is supposed to be A comparison of two animal welfare protocols for dairy cattle 6 inorganic, draining, non-absorbing material, soft, clean and dry. The knee-test was performed to check the last three items. The surface has to be under a slight angle if not consisting of a thick layer of sawdust or sand. Floor The floor was scored for its slipperiness, cleanliness and, loose or unequal slats. Also, the floor was observed for its coverage with rubber and for the ability of walking. The scoring was done by observations. Feeding fence The number of feeding places was counted when head gates were used. In case of a wooden beam or metal tube, the length was measured with a tapeline and the number of places was calculated, using 65 cm of space per cow. The height of the feeding fence and the contamination of food were judged on account of observations. Water The number of drinking places was counted when small waterers like bowls were used. If large waterers were present, the drinking space was measured with a tapeline and the number of drinking places was calculated, using 65 cm per place as the ideal number. Waterers were also scored for type, cleanliness and the temperature of the water. Waiting room and milking parlor The items from this chapter are behaviour during milking and milking time. These scorings were made on the basis of the questionnaire. Alleys and walkways The space of the alleys and passages in the barn were scored. A tapeline was used for the measurements and the number of passages was counted. Miscellaneous This item consists of four scoring points based on the presence of a maternity pen, sick bay, (motorized) brush and access to pasture/outside paddock. Animal (health and feeding) Twelve points are scored, all considering the cow’s health and body condition. Most points were scored on the basis of the questionnaire, but some points, like hair cover, body condition score and filling of the rumen, were scored by observations of the cows. Analysis and Statistics After collecting the data of a farm, the data were processed in an Excell file. The total score of the farm was calculated as a summary of the different scores. The total score and the separate items of the cow-comfort scoring system were statistically analysed using SPSS. For determining a linear connection between variables, correlation and regression were used. With correlation, the strength and the direction of the connection were determined. This was reproduced by a non-parametric Spearman correlation-test, with values between -1 and +1. For each combination of two variables the twotailed significance with a reliability of 99% and 95% was determined [14]. A comparison of two animal welfare protocols for dairy cattle 7 Welfare Quality protocol The second scoring system used is the Welfare Quality assessment protocol for dairy cows. This protocol analyze data about good feeding, good housing, good health and appropriate behaviour. During the scoring any disturbance of the animals was avoided as far as possible. Also the animals observed were not touched. For some of the measures, random sampling was required. The sample size for clinical scoring depended on the herd size. For the sample size a table could be checked [Appendix 4]. The measures apply to all dairy cows (lactating and dry) and to pregnant heifers if they are kept together with dairy cows. For some measures the stable had to be divided in segments of 25 animals maximum, which were watched for at least ten minutes each. All the observations made were completed on a specially designed form [Appendix 5]. Some questions had to be asked to the farmer for which a management questionnaire was used [Appendix 6]. Good feeding The welfare criteria for good feeding are absence of prolonged hunger and thirst. For the first criteria the body condition score is measured. For the second criteria water provision, cleanliness of water, water flow and functioning of water points is measured. Body condition score The animal was observed from behind and from the side, but not touched. Four criteria were taken into account: cavity (around the tail head, loin, vertebrae and the tail head), hipbones, spine and ribs. On individual level cows were logged as 0 - regular, 1 – very lean or 2 – very fat. Water provision All water points within the area of the animal unit were assessed. The type and number were checked. In case of open troughs the length was measured with a tapeline. The cleanliness of the water was checked regard to the presence of old or fresh dirt on the inner side as well as staining of the water. 0 – clean, 1 – partly dirty, 2 – dirty. Water flow had to be checked in all cases except in case of troughs with a large reservoir. To be sufficient the water flow had to be at least 10 L/min in case of a bowl and 20 L/min in case of a trough. This was checked by filling it up to the brim and then collecting the overflow for 1 minute using a bucket. All drinkers were checked if levers are movable and that water flows if they were removed. Good housing The welfare criteria for good housing are comfort around resting, thermal comfort and ease of movement. Comfort around resting consist off time needed to lie down, animals colliding with housing equipment during lying down, animals lying partly or completely outside the lying area, cleanliness of udders, flank, upper and lower legs. For the thermal comfort no measure is developed yet. Ease of movement contains presence of tethering, which is not in question in our research, and access to outdoor loafing area or pasture. Comfort around resting Time needed to lie down was recorded with a camera. Time recording of a lying down sequence started when one carpal joint of the animal was bent and lowered (before touching the ground). The whole lying down movement ends when the hind quarter of the animal had fallen down and the animal had pulled the front A comparison of two animal welfare protocols for dairy cattle 8 leg out from underneath the body. Time was recorded in seconds, the herd level was the mean time to lie down in a sample of 6 cows at least. The duration of a lying down movement was only taken when undisturbed by other animals or human interaction in the supposed lying area. During lying down the cows weren’t supposed to collide with housing equipment. The collision was obviously seen or heard, usually with hind quarter or side and recorded continuously. 0 – No collision, 2 – Collision. During observations of segments of the barn, the number of animals which were lying were assessed. Of these lying cows the number of cows lying with their hind quarter in the edge of the cubicle or lying with their hind quarter completely outside the supposed lying area were assessed. Cleanliness of the applicable body parts is defined as the degree of dirt on the body parts considered, like splashing and plaques. Checked by watching the cow closely, the scores for cleanliness was: 0 – no dirt or minor splashing, 2 – separate or continuous plaques of dirt. Ease of movement All the stables visited were loose housing systems. With the management questionnaire farmers were asked if the cows had access to an outdoor loafing area or pasture. Good health Good health welfare criteria are absence of injuries (lameness or integument alterations), diseases and of pain induced by management procedures. Injuries. Diseases checked are coughing, nasal discharge, ocular discharge, hampered respiration, diarrhoea, vulvar discharge and milk somatic cell count. Criticised management procedures are disbudding/dehorning and tail docking. For the clinical scoring, a table was made, which was used when the cows were watched closely, to score the cows more quickly and accurate [Fig 1]. CLINICAL SCORING Ear tag no. Breed Body condition score 0 Cleanliness Legs 0 Flank 0 Udder 0 Integument Hairless Tarsus Hindquarter Neck/shoulder/back Carpus Flank/side/udder Other Clinical signs Nasal discharge 0 Ocular discharge 0 Hampered respiration 0 Diarrhoea 0 Vulvar discharge 0 Lameness 0 dairy 1 dual purpose 2 2 2 2 Lesion X X X Swelling 2 2 2 2 2 1 X X X X X 2 Fig 1. Table used scoring the cows in the stable. [23] Absence of injuries Lameness describes an abnormality of movement, caused by reduced ability to use one or more limbs in a normal manner. It can vary in severity from reduced ability to inability to bear weight. 0 – Not lame (timing of steps and weightbearing equal on all four feet), 1 – Lame (imperfect temporal rhythm in stride A comparison of two animal welfare protocols for dairy cattle 9 creating a limb), 2 – Severely lame (strong reluctance to bar weight on one limb, or more than one limb affected). Integument alterations are hairless patches, lesions and swellings. Only skin alterations of a minimum diameter of 2 cm at the largest extent are counted. Criteria of a hairless patch are area with hair loss, skin not damaged, extensive thinning of the coat due to parasites or hyperkeratosis possible. Criteria for lesions and swelling are that the skin is damaged, dermatitis due to parasites, completely or partly missing teats or ear lesions due to torn off ear tags. Five body regions on one side of the focal animal were examined with regard to this criteria. In the clinical scoring table “yes or no” and any lesions are filled in. Absence of disease Coughing is defined as a sudden and noisy expulsion of air from the lungs. This was noted when examining the segments. Nasal discharge is defined as clearly visible flow/discharge from the nostrils; transparent to yellow/green and often of thick consistency. Ocular discharge is defined as clearly visible flow/discharge (wet or dry) from the eye, at least 3 cm long. Hampered respiration rate is defined as deep and laboured or overtly difficult breathing. Diarrhoea is defined as loose watery manure below the tail head on both sides of the tail, area affected at least the size of a hand. Vulvular discharge is defined as purulent effluent from the vulva or plaques of pus on the bottom of the side tail. Viscous mucus in animals in late pregnancy was not counted. For these last five disease scoring was as follows 0 – No evidence, 2 – Evidence of the disease. Using the management questionnaire farmers were asked about the somatic cell count, mortality, dystocia and downers cows. 0 – Somatic cell count below 400.000 within 3 months, 2 – Somatic cell count of 400.000 or above within 3 months. Mortality is defined as the ‘uncontrolled death of animals as well as case of euthanasia and emergency slaughter. Dystocia is defined as the number of calvings where major assistance was required during the last 12 months. Incidence of downer cows is defined as the number of cases of non-ambulatory cows during the last months. For these three criteria percentage were taken into account. Absence of pain induced by management procedures The farmers were asked about the procedure of disbudding/dehorning and tail docking practices on the farm, like percentage of the calves/cows, age, method and analgesics. This was filled in on the management questionnaire. Good behaviour The welfare criteria for appropriate behaviour are expression of social behaviours, expression of other behaviours, good human-animal relationship and positive emotional state. Measures are agonistic behaviours, access to pasture, avoidance distance and qualitative behaviour assessment. Expression of social behaviours Social behaviour related to fighting is defined as agonistic behaviours and includes aggressive as well as submissive behaviours. Observation took place in segments of the barn. Agonistic behaviours recorded were head butts, displacement, chasing, fighting and chasing-up. Expression of other behaviours The availability of access to a pasture or to an outdoor loafing area was checked. Also the farmer was asked about the possibility and the amounts of time spend there. A comparison of two animal welfare protocols for dairy cattle 1 0 Good human-animal relationship Avoidance distance was used to test the human-animal relationship. This test was started when at least 75% of the cows were back in the stable after milking. The investigator was standing on the feed bunk at a distance of 2 m in front of the animal to be tested. If the distance to the feeding fence was less then 2 m an angle up to 45o with the feeding fence and a distance of 2,5 m was chosen. The head of the animal had to be completely past the feeding rack. The animal had to be attentive or took notice of the presence of the investigator. The animals were approached at a speed of one step per second and a step length of approximately 60 cm with the arm held overhand at an angle of approximately 45o from the body. When approaching the back of the hand was directed towards the animal and the animal was not looked into the eyes. The definition of withdrawal is when the animal moves back, turns the head to the side or pulls back the head trying to get out of the feeding rack, head shaking could also be found. The distance between the muzzle of the cow and the hand was estimated in case of withdrawal. Ear tag number of the cow and the distance to the cow were noted. The percentage of animals that could be touched approached closer than 50 cm, approached 100 to 50 cm and cows that could not be approached as closely as 100 cm were taken into account. Positive emotional state Qualitative behaviour assessment considers the expressive quality of how animals behave and interact with each other and the environment, i.e. their ‘body language’. Depending on the size and structure of the farm several observation points were selected. The investigator waited a couple of minutes before starting the measures, which allowed the animals to return to undisturbed behaviour. The expressive quality of their activity was noted on a visual analogue scale [appendix 7]. ‘Minimum’ means entirely absent, ‘maximum’ means that this expressive quality is dominant across all observed animals. The distance between the minimum point to the point where the line crosses the scale was measured an taken into account. Terms used for dairy cow qualitative behaviour assessment are active, relaxed, fearful, agitated, calm, content, indifferent, frustrated, friendly, bored, playful, positively occupied, lively, inquisitive, irritable, uneasy, sociable, apathetic, happy and distressed. Statistic analysis After collecting the data of a farm, the data were processed in an Excell file. The score of the farm was calculated with the aid of the welfare quality protocol and the process program available on the following site: http://www1.clermont.inra.fr/wq/index.php?id=simul&new=1&situation=DCF Average scores were needed which were calculated before. The final results were correlated using a scale from 1 to 4. To compare the two systems, the results from both systems were converted to a scale from 1 to 4 [Table 1]. For the cow comfort scoring system these scores were based upon the results of previous investigations and the present study. Correlations between were statistically analysed using SPSS. Overall welfare Total score 1 Not classified < 150 2 Acceptable 150 – 250 3 Enhanced 250-350 4 Excellent > 350 Table 1: Total scores converted to a scale from 1 to 4. A comparison of two animal welfare protocols for dairy cattle 1 1 4 Results The execution of both systems differed substantial while the cow comfort score system examined particularly the environment of the cow, the Welfare Quality® protocol examined the condition of the individual cow. This meant that there was a substantial difference in time needed to examine the farms. For instance, by the cow comfort score system more cows are watched at the same time by which an average score is logged, like cleanliness of the cows. With the Welfare Quality® protocol a certain percentage of the cows is checked individually, the cleanliness of the lower hind legs, hind quarters and udder is noted by which an average is calculated. But as both systems were used more often, the execution went faster. Nevertheless, time needed for examining differed enormously. On a farm with 100 cows, applying the cow comfort score system lasted an hour and a half, applying the Welfare Quality® protocol took almost 7 hours. Despite the duration difference in execution the results of both systems had a correlation of 0.843 (P= 0.009). Scores achieved by the individual farms using the cow comfort score system varied from 55 until 330 points. The overall assessment of the farms with the welfare quality protocol varied from not classified to enhanced. As expected the systems are correlated, P = 0.009; R = 0.843.

A comparison of two animal welfare protocols for dairy cattle 1 6 5 Discussion Cow comfort score system The cow comfort score system is designed for Dutch farms and based on Dutch principles. Applying this system on Greek farms delivered occasional struggles, because of the different type of barns concerning for instance ventilation and cubicles. For an even better application of the system in Greece, it is recommended to adapt the system to the Greek farms. The cow comfort score system was easy and quick to use, because this system is more committed to assess the environment of the cow. The investigators checked particularly the standard elements in the stable. The more experience they had the faster the scoring took place. Stretching when raising from cubicles was sometimes hard to judge, not all the cows could be watched while standing up. Some of the cows who stood up were interrupted by the appearance of the investigators. Some of the cows got up and did not stretch, some did stretch. The influence by the presence of the investigators is difficult to determine. If possible it is an idea to put cameras in the stable to film the cows when they are really not interrupted by humans. However, with three points the influence on the total score is not very decisive. Standing idle on the other hand, has a lot more influence on the total score. The moment of a day at which a farm is visited, could have had influence on this item because of the different time schedule of farmers running their farm. When entering the barn standing idle was scored directly, to minimize the influence of the investigators entering. But because more people were working on the farm a visit of the farmer or his worker to the stable moments before the investigators entered maybe influenced the behaviour of the cows. The floor of the farms was cleaned using a scraper. These scrapers were particularly activated during milking. So when visiting a farm a couple of hours after the scraper did his last round, the floor was scored lower than just after the scraper was in action. Not only the time of the day but also the circumstances each day is important, because each day can be different concerning the weather. It would be ideal to visit farms more than once at different moments of a day to accurate scores gives to the farms. Welfare Quality® protocol Also for the Welfare Quality® protocol stables with cubicles were needed. So to use the system in the future adaptation of the system to Greek farms is recommended for a better application. Execution of the Welfare Quality® protocol took many hours. The different subjects had to be examined during different parts of the day. For example the human-animal relationship had to be checked when all cows were eating. The positive animal state, coughing and expression of social behaviours had to be examined when cows were in their normal behaviour not interrupted by humans. The clinical scoring had to be done examining the cows closely. At last the water points were checked. Also some parts of the Welfare Quality® protocol can be taken into question. The Welfare Quality® protocol gives much attention to individual cows, about their emotional and physical state. This takes a lot of time to check the individual cows. To begin the necessary time to examine the individual cows could be shortened by using the minimum needed number of cows [Appendix 4]. The bigger the farm, the more cows needed for the research. All this without an impact on the result. Can we score welfare of cows faster than with the welfare quality protocol? 17 The human-animal relationship is checked individually by approaching cows during eating. Because of the large number of animals that had to be checked this took more time than told by the system. Cows next to a cow who was checked were not useful for a while because they were influenced by the investigator approaching the cow next to them. But do farmers ever approach their cows this way? We noticed that cows were not used to humans walking towards them during eating so most of the time more then only the neighbour cows were affected by checking a cow. Maybe because this is a total different way of approaching cows they are more afraid. Everything what is new is exciting, so cows that are not afraid of humans can be scored negatively. Maybe this item can be combined with the clinical scoring of the cows. Walking around a cow can also give a good indication of a cow being afraid or curious. Especially with behavioural measures the interpretation is more subjective. In the Welfare Quality® protocol a chapter is dedicated to the feelings of cows, called the positive emotional state. But how do we know if a cow is positively occupied, content, friendly, lively, sociable and happy? Even with the best training one can not know for sure how a cow feels deep inside just by looking at her. This is perhaps a chapter which can be revised. On behalf of the Welfare Quality® protocol the farmers need to give data of the somatic cell count. But many Greek farmers are not yet using computer systems for their administration. So they only know the total number of somatic cell count of the tank which the milk company gives them. Also for other data the reliability can be taken in question. A recommendation for next time is to select farmers with a proper administration, instead of using data stated by the farmer. The practical execution of the cow comfort score system versus the Welfare Quality® protocol As stated above, the practical execution of both systems differed substantially. The cow comfort score system is easy and quick to use because this system is more committed to assess the environment of the cow. With the Welfare Quality® protocol cows are examined individually, to check their emotional and physical state. For instance, time spend examining cow comfort. By the cow comfort score system more cows are watched at the same time, with the Welfare Quality® protocol a certain percentage of the cows is checked individually. Fear behaviour is checked with the cow comfort score by asking ‘do the cows remain quiet when entering the barn, are they scared or approach curiously?’ With the Welfare Quality® protocol the human-animal relationship is checked individually by approaching cows during eating. Examining cows individually takes longer and is more subjective. Examining the environment of the cow is objective and can be done quickly. Many agencies have contributed developing the Welfare Quality® protocol so this can be seen as a gold standard when we are talking about evaluating cow comfort. That does not mean that another system does not properly value the cow comfort on a farm. Using one method does not make another method unsuitable. Cow comfort becomes primarily visible through the body and behavioural language of cows. Building and stall design, climatic conditions, bedding type, floor, traffic lane surfaces, feed bunk amongst other things are considered in relation to cow comfort [17,19]. Certain factors do not require frequent monitoring. These factors are standard in the stable. Body language is often clearly expressed in the ways stalls are used. For instance crowding of cows in a barn location, stall refusal, long standing and apprehensive behaviour before lying are examples of mismatch with managerial practices and/or environmental conditions. Checking of the environment is important to see if a cow can behave Can we score welfare of cows faster than with the welfare quality protocol? 18 the way it is suppose to behave. To check if a cow can drink and eat, walk and sleep as much as she needs to be in a physical and psychological state of harmony with herself and her environment. Examination of the environment of the cow is objective. Checking cows individually gives an indication of their emotional state. To have a good indication many cows need to be checked, this takes longer. Furthermore, it is also subjective, because one can never know exactly how a cow truly feels. On a farm with 100 cows, applying the cow comfort score system lasted an hour and a half, applying the Welfare Quality® protocol took almost 7 hours. The Welfare Quality® protocol took so long that it was hard to keep concentrated and moments of boredom were impossible to circumvent. But because all the farms were only scored once, time and weather differences lurk, although maybe not of influence, and moment of scoring is a snapshot. It would be ideal to visit farms more than once at different moments of a day to accurately give scores to the farms. The total score of the cow comfort scoring system versus the total score of the Welfare Quality® protocol. 5.1 Cow comfort scoring and welfare Quality® protocol As expected the results of this study demonstrate a positive significant correlation (P = 0.009; R = 0.843) between the cow comfort scoring system and the Welfare Quality® protocol [table 2]. Farm Cow comfort scoring Welfare Quality® Total Total 1-4 Total 330 3 3 1 184 2 2 2 191 2 3 3 137 2 2 4 264 3 3 5 55 1 1 7 318 3 3 8 280 3 3 9 Table 2: Total scores compared from farm 1 to 9. protocol Overall welfare Enhanced Acceptable Enhanced Acceptable Enhanced Not classified Enhanced Enhanced Only one farm, farm 3, differed one point. Farm 3 and 5 were scored with both systems on the same day. Farm 9 had only one day in between. Farm 1, 2, 4, 7 and 8 had more then seven days in between. The farms were also visited on a different time of the day. Next time, farms have to be visited more than once at different moments of a day to give an accurate score to the farms. 5.2 Walking and absence of diseases Walking scored with the cow comfort scoring system is correlated (P = 0.009; R = 0.842) with the Welfare Quality® criterion absence of diseases. Cows that are in good health walk more than cows that are ill [3]. So if the absence of diseases is increasing the score of walking is so too. This is a very high correlation. The total score of absence of diseases can be replaced by a locomotion score. Can we score welfare of cows faster than with the welfare quality protocol? 19 5.3 Width of walkways and alleys and positive emotional state There is a correlation between width of walkways and alleys of the cow comfort scoring versus the Welfare Quality® criterion positive emotional state (P = 0.025; R = 0.772). If cows can not pass each other easy this has a negative influence on their positive emotional state. Cows with more space in the feedalley reduce their frequency of aggressive interactions [6]. The dominant cows chase not dominant cows away therefore they can behave less in a natural way. They have to be more alert all the time and have a higher level of stress. 5.4 Standing idle and appropriate behaviour / total Welfare Quality ® protocol Standing idle of cows in the cow comfort scoring system is correlated with the Welfare Quality® principle of appropriate behaviour (P = 0.030; R = 0.756). The principle of appropriate behaviour includes expression of social behaviours and other behaviours, good human-animal relationship and the positive emotional state. When fewer cows are standing idle, the score is increasing so there is a positive correlation between standing idle and appropriate behaviour. There is also a very high correlation between standing idle and the total score of the Welfare Quality® protocol (P = 0.005; R = 0.866). Maybe it is even enough to only check the cows that are standing idle. Further investigation has to prove this outcome. 5.5 number of waterplaces and good health The number of waterplaces in the cow comfort scoring system are correlated with Welfare Quality® principle good health, P = 0.043; R = 0.722. Water is of course very important for good health. Depending on the production cows need 75 up to 180 litre of water every day [11]. Restriction of water intake results in a reduction in feed intake accompanied by a reduction in performance [2]. With all its consequences. Cows drink more then one quarter of their total daily water intake after milking. Water intake peaks corresponded to feeding and milking times. 75% percent of the cows visited waterers after the evening milking within 2 hours [4]. So the number of waterplaces should be able to meet this demand. When farms have a good water supply, normally several cases are well organized. Water supply can be used as an indicator for good health. There was no correlation with the Welfare Quality® protocol total score and housing, because al the farms had the same score, but to our opinion there was a great difference in housing between the farms. The Welfare Quality® protocol only checks the comfort around resting and the ease of movement. So only the cubicles and if the cows are tethered or walked freely, in or outside, was checked. Some cubicles used sand, some a mattress and some dried manure. This can also affect the cow and her welfare. Visiting the farms showed us a big difference in housing between the farms, but no difference was made by the Welfare Quality® protocol. The results of examining cow comfort of both systems are correlated. But although there is a very good correlation between the total score of both systems, there are not many correlations between the different parts of the systems. One possible reason for this phenomenon is the total different type of scoring the data. Scoring individuals cows versus scorings their living conditions. Another reason can be the calculations that have to be done with the data obtained with the Welfare Quality® protocol. The calculation for the Welfare Quality® protocol are very complicated. For all the collected data special formulas are designed. For example, to score the absence of prolonged hunger the percentage of very lean cows have to be calculated (I). I = 100 - % of very lean cows. When I ≤ 20 then Score = (111 x I) – (1.39 x I2) + (0.00584 x I3). When I ≥ 20 then Score = 2960 + (0.222 x I) – (0.00277 x I2) + (5.93 x 10-5I3). On the internet there is a Can we score welfare of cows faster than with the welfare quality protocol? 20 possibility to fill in the data in a program which will calculate the results. This is really an outcome, because working with the data is a whole day’s work for each farm. But care most be given to avoid typing and calculation errors. A disadvantage is that there is still much preparatory work to be done before the data can be entered in the program. Also the results give no overview of the different scored items, but only of the total welfare criteria and welfare principles. Calculations for the cow comfort score system can be done using a specially designed excel program. For each item the scores can be directly filled in. The total score of the chapters have a minimum and a maximum score. When scores are below the minimum extra points will be withdrawn. The system is very clear and easy to work with. Obviously care must be given to avoid typing errors. When a total score is generated it is directly clear what the good qualities of a farm are and where there is still room for improvement. Climate The climate in Greece differs from the climate in the Netherlands. During the presence of the investigators in Greece the weather was unusually rainy, fortunately it quickly changed to more sunnier weather. An optimal temperature range for high producing dairy cows is between -25 oC and +15 oC [7]. The thermoneutral zone for dairy cows is between the lower critical temperature, -16 to -37 oC, and the upper critical temperature, 20 – 26 oC [19]. Because Greece has the Mediterranean climate the temperature is most of the days above this range. Heat stress is therefore a big problem in Greece. Most practical methods to reduce heat stress are cooling, ventilation and group cows into shade [8,19]. All the farmers had a ventilation system to relieve heat stress, some had even a sprinkler system above the beds and in the waiting area. Most cows do not go outside so are always in the shade. Because the location were this investigation took place was close to the sea, it was generally very windy. But in summer this wind is not sufficient to eliminate heat stress. Difference in climate will affect the housing of animals, since there are other steps needed for an optimal housing for the cow. Can we score welfare of cows faster than with the welfare quality protocol? 21 6 Conclusion The results of this study show that both systems can be used to assess the welfare status of the cows on a dairy farm in Greece. The practical execution of the cow comfort scoring system is less time consuming and easier to perform than the Welfare Quality system. Since the number of farms studied in the present study is not large, more studies are needed to confirm the findings. It is recommended to adapt both scoring systems to local conditions, because farms depend on the country and the area where they are located.

Indications for the points can be found in the explanation. If the range is e.g. 0-15 points all numbers in between can be given as well. The points can be summed per chapter and totaled for the entire farm. If the minimum score for a chapter is not reached, this minimum needs to be subtracted from the total score.

For scared animals 0 points. When the animals approach you (curiously) 5 points. Stretching when raising from cubicle (3 points): If a cow lies comfortably, she will stretch before she leaves the cubicle. If she does 3 points, else 0. Tail is hanging straight and relaxed (3 points): Stressed cows don’t have a relaxed tail. With exited animals the tail can be straight up. If >90% of the cows has a relaxed, straight, tail, 3 points. When you see this with 80-90% of the animals 2 points, else 0 points. Bellowing (4 points): Restless behaviour is marked by bellowing. Animals in oestrus or with COF condition will bellow often. When there is no such a cow present < twice per 30 min: 4 points; twice per 30 min: 2 points, when > twice per 30 min: 0 points. Number of cows standing idle (-100 points): Cows should be standing only toe at and should be lying after that. The number of cows standing in walkways or in their free stalls is therefore a good ‘comfortindicator’. For each percentage of cows that is standing during a quiet period of the day (i.e. < 1 hr before milking): – 1 point Cows sleeping in walk ways (5points (or –10)) : Cows should not sleep in walk ways. If there are none: 5 points. If there is around 1 % of the cows: 0 points; when more: - 10 points. Noise (-5 points) Cows don’t like noise in their environment. If there is a lot of noise from tractors, shouting, etc. give – 5 points. Some noise -3 points. Quiet situation 0 points. LIGHT: Sufficient light in the barn (10 points): Everywhere in the barn one should be able to read a newspaper without difficulties. When measured it should be > 100 Lux. Then give 10 points. When there is a moderate level or not at all places > 100 Lux, 5 points. When the level is low or bad sight at several places: 0 points. Period of light > 15 hours (5 points): When the photoperiod is long, cows feel better. Therefore, > 15 h: 5 points; 1215 h: 3 points; < 12: 0 points. However, if the lights are on 24h per day: 0 points. Period of dark > 6 hours (10 points): Rest is important for cattle. A period of darkness needs to included in the daily routine. The minimum is 6h: 2 points; 7h: 5 points and 8h: 10 points. However, if there are > 8h of darkness, the score drops again. Can we score welfare of cows faster than with the welfare quality protocol? 28 VENTILATION: It smells fresh (5 points): It should not smell after NH3, H2S, or other gasses. If the smell is bad: 0 points, not so fresh: 2 points. When there is a fresh, pleasant air: 5 points. This is about the air quality between the animals. Cobwebs (10 points): Cobwebs are seen at places with little airflow. If you see many cobwebs: 0 points; a few: 5 points; rare or none: 10 points. Condense / mould (10 points): Condensation of water along the ceiling or wall is an indication that the relative humidity is too high. If this happens often fungi will start to grow on the ceiling and walls. If you see heavy condensation or mould growth: 0 points; Dry clean walls and ceilings: 10 points. (and anything in between 0-10 points) Barn temperature (10 points): During summer the barn should be cooler than outside: Difference is 1- 5 ˚C: 5 points > 5 ˚C: 10 points In winter the difference should not be large: Difference is 0 - 2 ˚C: 10 points 2 - 5 ˚C: 5 points > 5 ˚C: 0 points If the temperature is 25 - 30 ˚C, subtract 5 points; > 30 ˚C, subtract 10 points Dead spaces (5 points): There should not be places in the barn that are not or poorly ventilated. If there are dead spaces: 0 points; else 5 points Drop of cold air/draught (10 points): Nowhere there should be draught or drop of cold air. This will stress the cows. If there is much draught: 0 points; Only in a corner or small part of the barn: 5 points; Nowhere: 10 points. FREE STALLS: Cows are clean (5 points): From clean to dirty: give 5 - 0 points. Bedding is made of inorganic material (5 points): If the bedding is made of sand or another inorganic, non absorbing, material: 5 points, else 0. Bedding is soft (10 points (or -10): Perform the knee test. Good result: 10 points; moderate 5 points; painful 0 points. If there is no bedding (hard concrete, do not perform a knee test!) – 10 points. Bedding is clean / dry ( 10 points): Clean and dry stalls: 10 points; some dirty stalls: 5 points; many stalls dirty: 0 points. Stall surface is under a slight angle (5 points): The angle should be between 3 and 7˚. Can we score welfare of cows faster than with the welfare quality protocol? 29 Bedding is flat (5 points (or -5)): Nice and smooth surface: 5 points. If there are object popping through the bedding (car tyres) or when there are large holes and an irregular surface: -5 points Withers bar (5 points): If the withers bar is not shiny > 95% of the free stalls: 5 points. If it is shiny in 520% of the stalls: 3 points. When > 20% of the stall has a shiny withers bar: 0 points. Lunge space (10 points): If there is ample lunge space: 10 points. Less, but still usable lunge space: 5 points. No lunge space: 0 points. Length / width of the stall (10 points): Stalls need to be of the right size. This is depending on the size of the cows. For Dutch HF cattle this means for wall-side rows: 270 x 120 cm; double (head to head) or inside (with an open head side) rows: 245 x 120. If the size meets the need of the cows 10 points; a bit too small: 5 points; too small: 0 points. Brisket board (5 points): No brisket board: 5 points; Smooth, rounded rubber tube: 2 points; hard rough wooden board: 0 points. If there is a tube hanging on two chains (‘variable brisket board’): 5 points. Number (–10 points): More or equal to the number of cows, 0 points. With 10% more cows than stalls: –5 points; If there is 20% or more overcrowding: –10 points. FLOOR: Slipperiness (10 points): The floor should provide sufficient grip: 10 points. When slippery: 0 points. Loose / unequal slats (10 points): If there are many loose and/or slats with rough edges: 0 points; For a smooth floor: 10 points. Rubber (10 points): If > 50% of the floor is covered with rubber: 10 points; 25 – 50 %: 7 points; 10 – 25 %: 5 points. Walking (10 points): If the cows walk with a firm stride: 10 points; cautious, slow, walking: 0 points. Cleanliness (5 points): Clean floor: 5 points; Dirty floor: 0 points. FEEDING FENCE: Head gates ( 1 points): With head gates 0 points. Only a rail, without head gates, 1 point Height (1 points): The height should be sufficient for the cows present, than 1 point. If not, 0 points Can we score welfare of cows faster than with the welfare quality protocol? 30 Number of places (3 points): The number of places should be at least the same as the number of cows (3 points). When there is 10% overcrowding, 1 point. When there is 20% overcrowding, 0 point. Contamination of food (-3 points): If food contains any undesirable debris it may affect cow’s health and comfort (wires, plastic containers, etc.); food must be free of any objects and look suitable for cows. If food looks “good” give 0 points, if it looks “bad” 3 points. WATER: Number of waterers (10 points): Per 10 cows there should be 1 drinking space. There should be at least 2 locations in the barn because of dominant cows. If these conditions are met: 10 points. Type (5 points): A large waterer: 5 points, small waterers: 0 points. Cleanliness (5 points): If the water is clean: 5 points Temperature (5 points): Luke warm water (15-25 °C): 5 points, cold water: 0 points. WAITING ROOM AND MILKING PARLOR: Behaviour (3 points): Are the cows quiet ? 0-3 points. Time (2 points): Are there cows that have to wait > 1 hr before milking? (Yes, 0 points; No, 2 points) ALLEYS AND WALKWAYS: Width of the walkway before the feeding fence (-2 - 2 points): This should be wide enough to let two cows pass in opposite directions behind an eating cow. This is, in general, 4 m. > 4 m: 2 points; 3,75-4 m: 1 point; 3,53,75m: 0 points; < 3,5 m: -2 points. Width other walkways and alleys (2 points): These paths need to be >3 m.

One passage per 10-15 cubicles: 1 point; > 15: 0 points. (NB In two row barns this item can be skipped) MISCELLANEOUS: Maternity pen (3 points): Contact with other cows Ample bedding (straw) Clean Enough space Can we score welfare of cows faster than with the welfare quality protocol? 31 Sick bay (2 points): Contact with other cows Ample bedding (straw) Clean Enough space Access to pasture / outside paddock (20 points): Do the cows have access to pasture? At all times During the summer, day and night During the summer at night Is it mandatory or voluntarily? Do the cows have shade in the pasture during hot summer days? Is there a (mechanical) brush ? (15 points): If there is a brush: 5 points If there is a mechanical brush: 15 points ANIMAL (HEALTH): Hair ( 5 points): Shaved/not shaved; hair that is upright; shiny; lesions; etc. Lameness (-25 - 25 points): Here cow-cases per year are indicated.

In such cases the cow is not harmed at that moment. The thickness is most probably caused by repeated trauma and an indication for reduced lying comfort. >80% per year -> -10 points 60-80% per year -> -8 points 40-60% per year -> -5 points 25-40% per year -> -2 points 15-25% per year -> 0 points 10-15% per year -> 5 points < 10% per year -> 10 points The hock can also be thicker with soft ‘tissue’.

Can we score welfare of cows faster than with the welfare quality protocol? 32 Thick carpi (-60 - 20 points): A carpus can be thicker through bone formation. In such cases the cow is not harmed at that moment. The thickness is most probably caused by repeated trauma and an indication for reduced lying comfort. >80% per year -> -10 points 60-80% per year -> -8 points 40-60% per year -> -5 points 25-40% per year -> -2 points 15-25% per year -> 0 points 10-15% per year -> 5 points < 10% per year -> 10 points The carpus can also be thicker with soft ‘tissue’.

Claws (20 points): Look at form, angle and standing. (Perfect claws get 20 points, poor ones: 0 points) When there are serious problems, the cows will walk lame. (So you will score them there as well). In general, cows with painful claws will be treated and therefore most cows will not have painful claws during the assessment. Mastitis (-15 - 15 points): Take into account the number of cow-cases per year. If a cow is considered healthy and after 14 days has a clinical case again, consider this as a new case. >80% per year -> -15 points 60-80% per year -> -10 points 40-60% per year -> -5 points 25-40% per year -> -3 points 15-25% per year -> 0 points 10-15% per year -> 5 points 5-10% per year -> 10 points <5% per year -> 15 points Abomasal dislocations (-15 - 10 points): >15% / year -> -15 points 10-15% per year -> -10 points 5-10% per year -> -5 points 0-5% per year -> 0 points 0% per year -> 10 points Filling of the rumen (-10 – 5 points): What is the general impression of all cows? Take a sample of 3 cows in each lactation stage. Bad –10 points sufficient 0 points Good 5 points Can we score welfare of cows faster than with the welfare quality protocol? 33 Milk fever (-10 - 5 points): >15% / year -> -10 points 10-15% per year -> -5 points 5-10% per year -> -2 points 0-5% per year -> 0 points 0% per year -> 5 points Cases in cows < 4 years count twice. Acetonemia (-15 - 5 points): >15% / year -> -15 points 10-15% per year -> -10 points 5-10% per year -> -5 points 0-5% per year -> 0 points 0% per year -> 5 points BCS (15 points): Calculate the average BCS for the dry cows over a year. They represent the result of the previous lactation and provide an indication of the level of NEB post partum. If the BCS is determined and the average is at the desired level, 15 points. For deviations of 0.5 points (up or down) 5 points reduction. If the deviation is > 1 point: 0 points. BCS can be determined in a (random) sample of 5 (dry)cows, when not determined regularly. The desired level may vary per country and breed. Fat % in the milk (15 points) Calculate the average % of fat in the milk for the first 3 weeks of lactation. Compare this with the average level for the breed and the country. If the level on the farm differs > 1% give 0 points; 0.5-1% give 7 points; < 0.5% 15 points. Fertility (-10 - 25 points): What is the impression of the fertility after working out the various indices? Good –> 25 points; reasonable –> 15 points; poor -> –5 points; bad -> –10 points.
