PRIORITIES OF TECHNICAL ISSUES TO BE RESOLVED IN SHEEP AND GOAT HUSBANDRY IN THE CEEC Martyniuk, Elzbieta Department of Animal Genetics and Breeding Warsaw Agricultural University Brwinow, Poland ————————————————————————————————————————————— ABSTRACT During the last four European Association for Animal Production (EAAP) meetings 13 countries in our region presented by papers in the sessions of the Sheep and Goat Commission. Sheep papers outnumbered goat papers, 122 to 18. The areas of interest, regarding sheep and goat husbandry are presented below: Meat production As meat production has become a very important direction in many of the Central and East European (CEE) countries, especially those exporting prime lambs to the EU market, there is a growing interest observed in the evaluation and comparison of different crossbreeding genotypes and various lamb slaughter production systems. Milk production In a few countries of our region, sheep have been milked for centuries and sheep dairy products are a traditional and important element in the human diet. So there are continuous efforts to increase milk production in those countries, through selection of local sheep populations or their upgrading with milk breeds. It is often connected with the introduction of dairy breeds like East-Friesian, British Milksheep or Awassi. Wool production With the introduction of a market economy, wool production lost its economic importance. No single paper addressed the problems of pasture quality, improvement or management. A growing interest in prolific breeds and improvement of fecundity in sheep flocks was also observed. Breeding strategies, for small flocks, mainly of native breeds and especially endangered ones, were presented as well as breeding methods aiming to build up slow virus resistance in sheep populations. Production systems / management In this section, papers dealt with evaluation of different production systems; i.e. the traditional Romanian transhumance system or the mixed grazing system and its implications on parasite control. Management practises were analysed in the light of production and productivity enhancement as well as improvement of profitability of sheep husbandry. Also, there were papers presenting national Programmes and strategies for development of the sheep sector in their countries. Breeds: development, characterization and adaptation Several papers were devoted to description of breeds and lines of sheep, especially newly developed synthetic lines or backcross lines. As the import of exotic germplasm is taking place in the sheep sector in the CEE countries, there were papers presenting performance of imported breeds and their adaptation to new environmental/management conditions. Only one paper, from Slovenia, addressed the problem of conservation of sheep genetic resources. Goats Papers on goats were not so numerous but their dimension was very wide and they addressed most of the issues already presented in the case of sheep research. Performance recording using test day model in dairy goats was investigated, as well as other management issues connected with milk production. Countries which imported 188 cashmere goats, such as the Czech and Slovak Republics, presented results on performance and utilization of these breeds. In most of the countries in the sheep sector it became necessary to change a production goal - from wool to meat - which required fundamental changes in flock breeding and management. Milk production was increasing in importance, one of the solutions to improving profitability. A new breeding law, which has already been implemented or is being developed, secures socialization of breeding, giving Sheep Breeders Societies new tasks and responsibilities over breeding. Livestock husbandry in the CEE countries in the future will have to observe the same welfare standards as are now applied in EU countries. ————————————————————————————————————————————— INTRODUCTION With rapid changes in sheep and goat husbandry in the CEE countries over the last several years, the preparation for this session was not an easy task as the background information which should be provided in the country reports were not available beforehand. Research should be, and usually is, a mirror in which we are able to observe a reflection of important issues to be sorted out and solved in livestock production. New developments in stock reproduction, management and utilization are always preceded by scientific experiments, analyses and evaluations. So my introduction to this session, dealing with technical issues in sheep and goat husbandry in the CEE countries, is also based on analysis of the area of scientific interest expressed in papers contributed by participants from the CEE countries during annual EAAP meetings in the last few years, from 1994 through 1997. Realizing the weakness of such an approach, as participation of different CEE countries in the EAAP meetings was not representative, and contributed papers did not necessarily represent the total dimension of research carried out in the country in question - nevertheless, this analysis may provide a useful background for our discussion. During the last four EAAP meetings, there were 535 papers contributed for Sheep and Goat Commission sessions, out of which 140 (26 percent) were by authors coming from our region. Thirteen countries were represented; in two cases there were joint papers by authors from different countries. The highest number of papers came from Poland (46), the Czech Republic (26), Hungary (16), Slovak Republic (15) and Romania (11). Bulgaria contributed 9 papers, Russia 7, Slovenia 5 and Yugoslavia 3 while Bosnia and Herzegovina, Kazahstan, Latvia and Macedonia prepared one paper each. The reasons for these differences vary, but most are due to financial limitations which make participation in the expensive EAAP meetings impossible. Distribution of papers based on different subjects Generally speaking, the papers were usually submitted to short communication sessions (64 percent), while our contribution in sessions devoted to highly specific subjects (i.e. alternatives to drug therapy in nematodic infection control, slow virus diseases, strategies for extensification or welfare aspects) was very limited. Sheep papers outnumbered goat papers, 122 to 18. The areas of interest regarding sheep and goat husbandry are presented below: 189 Papers Countries 122 11 Meat production 21 PL-9, CR-6, SR&RO-2, H&BG-1 Milk production 10 PL-3, BG, H &SR-2, CR-1 Wool production 10 BG-5, RO-4, PL-1 Feeding 18 PL-11, CR-3, H-2, SR&BiH-1 Reproduction 13 H-6, PL&SR-3, RO-1 Physiology 14 Pl-6, H-3, SR-2, BG,CR&SLO-1 Genetics and breeding 9 PL-4, CR-2, RUS,H&YU-1 Behaviour 5 RUS-4, SR-1 SHEEP Production systems / management 11 CR-6, H,LV,PL,R&YU-1 Breeds (development, characterization, adaptation) 9 PL&RO-3, CR,SLO&RUS-1 Miscellaneous (information system & microbial contamination) 2 SLO-1, SR-1 GOATS 18 7 Milk, meat, cashmere, genetics, reproduction and physiology 18 CR-6, PL-4, SR-3, SLO-2, KAZ, MAC&YU-1 Meat production As meat production has become a very important direction in many of the CEE countries, especially those exporting prime lambs to the EU market, there is a growing interest observed in the evaluation and comparison of different crossbreeding genotypes and various lamb slaughter production systems. Improvement of carcass quality will become a must when the trade of live animals is constrained, so utilization of USG measurements in prediction of leanness in breeding stock has been initiated in the Czech Republic and Poland. Meat quality, especially in connection with cold storage and fatty acids content, as well as different supplements in feeding, were also the subjects of many research projects. Milk production In a few countries of our region, sheep have been milked for centuries and sheep dairy products are a traditional and important element in the human diet. So there are continuous efforts to increase milk production in those countries, through selection of local sheep populations or their upgrading with milk breeds. On the other hand, in a few countries like Hungary or Poland, milk production is being introduced into lowland areas as an alternative possibility of sheep utilization which can improve profitability of this species. It is often connected with introduction of dairy breeds like East-Friesian, British Milksheep or Awassi. 190 Wool production With the introduction of a market economy, wool production lost its economic importance. In most of the countries, previously very much involved in the increase of wool yield and wool quality improvement, such research has been stopped. Nevertheless, there is still some interest in this area, mainly regarding utilization of typical wool/fur breeds, like Bulgarian Fine Fleece sheep or Karakuls. Feeding This was the second best represented field of research, concentrating mainly on diet composition, feeding level and their effect on lamb growth and carcass quality. There were also several papers analysing effects of different supplements in lamb and ewe feeding, especially in critical physiological periods such as pregnancy and lactation. Mineral and vitamin supplements were mainly investigated, but probiotics, yeast cultures, oilseeds and others were also included in quoted research. No single paper addressed the problems of pasture quality, improvement or management. Reproduction There was a wide dimension of research dealing with reproduction issues, from examination of reproduction systems (early mating, long-term utilization, seasonality, lambing interval) through utilization of biotechnology in reproduction, such as intra-uterine or cervicouterine insemination or IVF. A growing interest in prolific breeds and improvement of fecundity in sheep flocks was also observed. Physiology Papers on physiology were very much differentiated. Some analysed the status of biochemical polymorphism in different sheep breeds, trying to find a relationship between physiological markers and production traits; they also described concentration/activity levels of several compounds in blood and organ tissues in ewes. Energy metabolism was another area of research, with special interest in metabolic profile testing. Supplements in feeding were investigated in terms of health and fitness improvement. Genetics and breeding Papers addressing this field concentrated on the estimation of genetic parameters in newly developed synthetic lines, and on breeding value estimation using an animal model. Breeding strategies for small flocks, mainly of native breeds and especially endangered ones, were presented as well as breeding methods aiming to build up slow virus resistance in sheep populations. 191 Behaviour There was one main centre, Novosibirsk, Russia, submitting a series of papers on the role of domestic behaviour in different aspects of sheep production and husbandry. There was one more paper from the Slovak Republic considering ethics, ethology and welfare in animal husbandry. Production systems / management In this section, papers dealt with evaluation of different production systems; i.e. the like traditional Romanian transhumance system or the mixed grazing system and its implications on parasite control. Management practises were analysed in the light of production and productivity enhancement as well as improvement of profitability of sheep husbandry. Flock size effect on management strategies was considered. Also, there were papers presenting national programmes and strategies for development of the sheep sector in their countries. Breeds: development, characterization and adaptation Several papers were devoted to description of breeds and lines of sheep, especially newly developed synthetic lines or backcross lines. As the import of exotic germplasm is taking place in the sheep sector in the CEE countries, there were papers presenting performance of imported breeds and their adaptation to new environmental/management conditions. Only one paper, from Slovenia, addressed the problem of conservation of sheep genetic resources. Goats Papers on goats were not so numerous but their dimension was very wide and they addressed most of the issues already presented in the case of sheep research. Reproduction, physiology and genetic improvement were the best represented areas of interest. Performance recording, using test day model in dairy goats was investigated, as well as other management issues connected with milk production. Countries which imported cashmere goats, like the Czech and Slovak Republics, presented results on performance and utilization of these breeds. DISCUSSION These EAAP meetings provided an excellent forum for goat and sheep scientist of the CEE countries to present papers on our areas of research. Upon reading all these papers again, one may get a good picture of the present situation of the sheep and goat sector in our countries . There is a lot of similarity between most of the countries in our region, mainly because of the same economical and political conditions in which the sheep and goat sector had to perform in the past. At present, we are going through very similar changes and difficulties connected with the transition to a market economy. In most of the countries in the sheep sector it became necessary to change a production goal - from wool to meat - which required fundamental changes in flock breeding and management. Milk production was increasing in importance, one of the solutions to improving profitability. There are also attempts to develop alternative utilization of small 192 ruminants which may (and should) provide environmental services, based on controlled grazing, to manage landscape and protect biodiversity. A severe breakdown of the public sector in agriculture, leading to liquidation of many flocks of high genetic value, changed totally the flock structure and active population structure. It had undesirable implications in breeding, especially performance recording and selection. Instead of dealing with big state flocks, the genetic progress now has to be achieved and implemented in relatively small private flocks. It is extremely difficult in the situation where profitability of the sector is low; thus there is a limited interest in investing in high quality breeding stock. Because of that, genetic improvement in purebred populations was very low, if anything, in recent years. At this same time, our countries are going through major changes regarding organization of breeding. A new breeding law, which has already been implemented or is being developed, secures socialization of breeding, giving Sheep Breeders Societies new tasks and responsibilities over breeding. It is a great challenge, but with time and increasing experience it should provide new opportunities and incentives for development of the sector. With such external economical conditions, which are forcing farmers to extensification and decrease of inputs, the production of high quality slaughter lambs has to be carried out. With the new production goals, there are many questions to be asked regarding flock management, and especially nutrition. Do we know well enough how to feed sheep which are supposed to produce meat instead of wool? Is our understanding of meat sheep mineral and vitamin demands sufficient, especially in the light of extensification and production based on grass, where soil quality and pollution may be of a great importance. Do we realize various consequences of macro- and microelement deficiency in fast growing ruminants? Similar questions apply to high yielding milking sheep or dairy goats. I believe that in sheep husbandry we are on the eve of the revolution which has already taken place in the pig sector, introducing a new concept of balancing the daily feed ratio. Reproduction is the second crucial area in terms of profitability of the sector. Most of all, we have to question whether the present level of reproduction performance is satisfactory or if it should be increased; in other words, what is the optimum litter size for the resources available, both feed and labour. If the proliferation is sufficient we have to know how to handle the extra lambs. Where the litter size has to be increased, it is an open question: how to proceed, applying selection, population screening and open nucleus system , upgrading or crossbreeding with prolific breeds or introducing a single gene. The answer has to be worked out according to national, regional or local conditions. Intensification of reproduction, e.g. three lambings in two years time, although hardly justified in most of the systems might be useful in specific circumstances. The same remark applies to eastrus synchronization and utilization of different drugs to increase ovulation rate. Health status is the next issue to be considered, especially in the present situation. The main health problems usually arise from malnutrition or lack of hygiene; many sheep diseases are connected with poor management. Parasites are another common problem, which may increase in importance in time as many of them are becoming resistant to various drugs. Specific and most dangerous diseases like scrapie or medi visna are still not fully registered - there is a question of their dimension in our stock as well as the availability of facilities to identify them in our countries. Prophylactic treatment in many flocks is still incidental although there are many flocks where permanent programmes are applied. Organization and availability of veterinary services is an important issue; so is the relationship between farmers and vets. In our countries, legal entitlements of farmers to perform veterinary care is rather limited and it is something to be changed in the future. 193 When considering flock management practises which may be applied at present in countries of our region, it can be said that they have to be adapted to changing production goals. In lamb slaughter production crossbreeding should be utilized as much as possible while breeding season, product quantity and quality should be adjusted to market demands. In dairy sheep, “saving milk” rearing methods as well as year-long milk production have to be developed to provide continuous milk and dairy products to supply the market. A lot of marketing and advertising has to be done to establish and strengthen sheep and goats products on our market, as well as introduce them to the export markets. Flock management practices have to improve profitability, which at present means primarily a decrease in inputs and increase in performance. In future, it will depend more and more on improvement of product quality and development of the market. Finally, an issue which tends to be forgotten in our countries at the moment; in the future Livestock husbandry in the CEE countries have to observe the same welfare standards as are now applied in EU countries. In the sheep and goat sector will be much easier to implement than in the pig and poultry sector. Nevertheless, we should think about it beforehand. REFERENCES EAAP. 1994.
