S. Meena 2 & M. K. Ghosh 1 & Champak Bhakat 1 & T. K. Dutta 1 Received: 18 July 2016 / Accepted: 26 January 2017 / Published online: 11 February 2017 # Springer Science+Business Media Dordrecht 2017 Abstract Livestock is a one of the major sources of livelihood for most of the small and marginal farmers in India, particularly for rural households who live in below poverty line. Extension interventions have long been seen as a key element for enabling farmers to obtain information and technologies that can improve their livelihoods. It is also recognized that extension is an important factor in promoting dairy development. Ex-post-facto cause to effect research design was applied in this study to trace out the impact of extension interventions in improving knowledge, attitude, adoption towards scientific dairy farming practices and improvement in milk production of dairy animal and income from dairying which will be resulted into improved livelihood of rural poor * Sanchita Garai sanchita.bckv@gmail.com in Nadia district of West Bengal, India. Therefore, 60 dairy farmers of experimental villages who were considered as beneficiaries and 60 dairy farmers of control villages who were considered as non-beneficiaries were selected as sample for the study. It was found that beneficiaries had significantly higher score in all the five components of livelihood improvement with its all sub components, i.e., knowledge, attitude, adoption of scientific dairy farming practices, milk production per household per day and monthly income from dairying except disease control, and marketing component of adoption. Hence, it may be concluded that extension interventions had a significant impact on improving livelihood of rural dairy farmers in Nadia district of West Bengal, India. Keywords Extension intervention . Livelihood improvement . Dairy farmer Suman Garai garaisuman1991@gmail.com Introduction Sanjit Maiti sanjit.ndri@gmail.com During the pre-independence era, agriculture was the main source of livelihood for majority of the rural households in India. With the increase in population, declining land-man ratio and increasing mechanization in farm operations, agriculture alone is not able to provide adequate income and employment to meet the needs of the rural households (Singh 2008). The crop-livestock mixed system is one of the most important characteristics of Indian agrarian economy, wherein crops and livestock symbiotically contribute to the growth and sustainability of each other. Livestock is one of the major sources of livelihood for most of the small and marginal farmers in India, particularly for rural households who live in below poverty line. Income from crop production is not always reliable due to several reasons like inadequate land holdings, not assured irrigation and non timely supply of B. S. Meena bmeena65@gmail.com M. K.

Therefore, rural farm families also maintain different species of livestock for their livelihood. Although India has the highest livestock population and milk production in the world, but the productivity, particularly of large ruminants, has always been a matter of concern. Therefore, to improve productivity, technology generation and dissemination and support services are the most critical factors which need to be geared up for the success of any livestock improvement program, particularly dairy husbandry program. It is also further necessary to bring all the stakeholders engaged in animal husbandry on a common platform for the success of the program. Extension program can ensure participation of all the stakeholders particularly small and marginal dairy farmers, women headed families, poor and weaker sections of the society. It is quite often impossible to ensure effective transfer of technologies needed for enhancing the productivity of dairy animals without an effective extension intervention. In relation to its role in rural livelihoods, agricultural extension encompasses the entire set of organizations that support and facilitate people engaged in agricultural production to solve problems and to obtain information, skills, and technologies to improve their livelihoods and wellbeing (Birner et al. 2006). Since a livelihood comprises the capabilities, assets and activities required for a means of living, it appears that agricultural extension intends not only to increase productivity and income (Anderson and Feder 2007; Waddington et al. 2010) but also to improve multifaceted aspects of rural life. Often times, extension impacts have been associated with improvements in productivity and household income. A worldwide review of extension services shows that the impact of extension services on rural livelihoods is mixed from very high rates of return in some cases and negligible achievements in other cases (Rivera et al. 2001; Anderson and Feder 2007). It is also widely acknowledged that estimation of extension impact on rural livelihoods is challenging in terms of dealing with attribution issues and linking cause and effect quantitatively (Anderson and Feder 2007). Therefore, it is conceptualize to assess the impact of organized extension interventions in the livelihood of resource poor dairy farmers. Materials and methods Locale of the study and sampling plan The present study was purposively conducted at two adopted villages of Eastern Regional Station (ERS) of ICAR-National Dairy Research Institute (NDRI), Kalyani, West Bengal, India, namely Muratipur and Dakkhin Chandamari. These two villages are situated in the Chakdah Community Trop Anim Health Prod (2017) 49:641–648 development Block of Nadia district, West Bengal. ERS of ICAR-NDRI, conducted/arranged different types of extension activities through their own innovative model of conducting extension program i.e. Dairy Vikash Kendra (Glimpse of Dairy Vikash Kendra is presented in box 1) in these two villages. Therefore, these two villages were considered as experimental villages and another two nearby villages namely Alaypur and Iswaripur of Chakdah Community development Block of Nadia district, West Bengal, also were selected on the basis of similar socio-economic-cultural background. These two villages were considered as the control villages. Hence, four villages were covered under this study. Thirty dairy farmers were selected randomly from each selected villages. Thus, total sample size of the present study was 120. Box 1: Dairy Vikash Kendra Dairy Vikash Kendra of Eastern Regional Station of ICAR-National Dairy Research Institute was established on January 2014 at Muratipur village, Chakdah, Nadia with the aim of conducting farming system research and extension program for the development of small holder dairying in West Bengal. Following services are provided through Dairy Vikash Kendra. • Educate the farmers on latest innovation of dairy science • Promoting AI in Cattle • Organizing fertility and veterinary camps • Providing necessary treatment to the livestock by arranging vaccination and deworming camps • Demonstrate fodder crops and latest varieties at farmers’ field • Promoting green fodder cultivation among the dairy farmers Research design used Ex-post-facto cause to effect research design was used in this study. Ex-post-facto research is a systematic empirical inquiry in which the scientist does not have direct control of independent variables because of their manifestations have already occurred or because they are inherently not manipulable. In ex-post-facto design, the treatment is determined not by manipulation but by selection. According to Mulay and Sabarathanam (1980), Seltiz et al. (1976) and Ray and Mondal (2006) ex-post-facto research design are two types viz. Ex-post-facto cause to effect research design and Expost-facto effect to cause research design. Therefore, to measure the impact of extension interventions in improving livelihood of dairy farmers, ex-post facto cause to effect research design was used. This situation may be diagrammatically represent in Fig. 1. Here pre-assumed effect, i.e., change in knowledge, attitude, and adoption of scientific dairy farming practices, milk production and monthly income from dairying, is due to cause of various type extension interventions arranged by the Eastern Regional station of ICAR-NDRI (Table 1).

Knowledge towards scientific dairy farming practices was measured with the help of knowledge test developed by Khatik (1994). Attitude towards adoption of scientific dairy farming was measured by attitude scale developed by Singh (1994). Adoption of scientific dairy farming practices (including five pillars of scientific dairy farming viz. breeding, feeding, management, disease control and marketing) was quantified by adoption index developed by Sharma & Sohal (1987). Knowledge test developed by Khatik (1994), attitude scale developed by Singh (1994), and adoption index developed by Sharma and Sohal (1987) were suitably modified keeping in the view of difference of the study area and time frame. To quantify the impact of extension intervention, two sets of samples, i.e., beneficiary (farmers of experimental villages) and non-beneficiary (farmers of control villages) were taken into consideration. Both the samples were drawn from same socioeconomic background and assumed that difference between the score of beneficiary and non-beneficiary was due to the extension interventions and it was hypothesized that farmers of experimental villages were having more knowledge, attitude, adoption towards scientific dairy farming practices as well as more milk production and income from dairying than the non-beneficiary. Non-parametric Mann Whitney BU^ test was applied for the confirmation of the difference of both beneficiary and non-beneficiary. Two success stories were also documented to ensure the benefits of extension interventions at micro-level. Results and discussion Assessment of impact of extension interventions on knowledge regarding scientific dairy farming practices Knowledge regarding scientific dairy farming practices among the both beneficiary and non-beneficiary was assessed in four aspects of scientific dairy farming practices viz. breeding, feeding, healthcare, and management. It was observed from Table 2 that mean score of knowledge about scientific breeding practices of beneficiary farmers of experimental villages and non-beneficiary farmers of control villages were 11.23 ± 0.23 and 8.82 ± 0.19, respectively. The same table also depicts that knowledge on scientific dairy farming practices of beneficiary farmers was significantly (p < 0.01) higher than the non-beneficiary farmers. Data presented in the same table also clearly depicted than mean score of knowledge regarding feeding practices of beneficiary farmers of experimental villages was significantly (p < 0.01) higher than the nonbeneficiary farmers of control villages. Table 2 also clearly mentioned that mean scores of knowledge regarding health care practices of dairy animals of beneficiary farmers and Trop Anim Health Prod (2017) 49:641–648 non-beneficiary farmers were 10.12 ± 0.26 and 7.62 ± 0.22, respectively. This result explained that farmers of experimental villages had significantly (p < 0.01) higher knowledge regarding healthcare of dairy animals than the non beneficiary farmers of control villages. Health related issues of the dairy animals of experimental villages were regularly intervened by the Dairy Vikash Kendra. This may be the reason of higher knowledge of dairy farmers of experimental villages. In case of knowledge regarding management practice of dairy animals, beneficiary farmers were having significantly (p < 0.01) higher knowledge than the non-beneficiary farmers. Like different components of knowledge regarding scientific dairy farming practices, overall knowledge regarding scientific dairy farming practices possessed by the dairy farmers of experimental villages was significantly (p < 0.01) higher than the dairy farmers of non-experimental villages. The results indicated that extension interventions had a positive impact in improving knowledge base of the beneficiary farmers. Beneficiary farmers attended several trainings, awareness camp, demonstration, read extension literatures etc. and these may be the reasons of improved knowledge base of beneficiary farmers than non-beneficiary farmers. Sahu et al. (2010) said that knowledge gain level was high (80%) in training + demonstration + literature followed by training + demonstration (75%), demonstration (40%), and training (35%) when training was conducted on vermicompost. The findings of the present study were in agreement with Sivashankar and Khedgi (2011) who studied in Sandur taluk of Bellary district in Karnataka state, covering 100 SHG members to obtain impact of training program on knowledge level and improvement in their economic status which indicated that training had a definite impact on the knowledge level of the respondents. Kumar et al. (2013) revealed that there was highly significant difference in the knowledge level of the farmers’ interest groups of vellore district of Tamilnadu on cattle feed combinations before and after training. Biswas et al. (2008) reported that there was a significant difference in knowledge of respondents on deworming, artificial insemination and vaccination as a result of training. Assessment of impact of extension interventions on attitude towards adoption of scientific dairy farming practices In the present study, attitude towards adoption of scientific dairy farming practices was conceptualized as the positive outlook of the dairy farmers towards adoption of scientific dairy farming practices to improve the status of their own livelihood. From the Table 3, it was observed that mean score of attitude towards adoption of scientific dairy farming practices of beneficiary farmers of experimental villages and nonbeneficiary farmers of control villages were 31.93 ± 0.35 and 28.77 ± 0.39, respectively. This result demanded that Trop Anim Health Prod (2017) 49:641–648 Table 2 Assessment of impact of extension interventions on knowledge regarding Scientific dairy farming practices 645 (Mean ± SE) Component of Knowledge Experimental villages (n = 60) Mann Whitney U Statistics U Statistics Z value P value Breeding Feeding 11.23 ± 0.23 7.42 ± 0.20 8.82 ± 0.19 5.18 ± 0.21 541 598 −6.71 −6.37 0.000 0.000 Healthcare 10.12 ± 0.26 7.62 ± 0.22 615 −6.30 0.000 Management Overall Knowledge 5.72 ± 0.16 34.47 ± 0.61 4.23 ± 0.16 25.85 ± 0.57 788 340.50 −5.45 −7.67 0.000 0.000 beneficiary farmers of experimental villages were having significantly (p < 0.01) higher positive attitude towards adoption of scientific dairy farming practices than non-beneficiary farmers of control villages. Scientists of the ERS of ICARNDRI used to visit the villages in a regular interval. Therefore, close contact with technocrats and constant support through the Dairy Vikash Kendra made the dairy farmers of experimental villages more confident to adopt scientific dairy farming practices. These may be the reason of more positive attitude of the dairy farmers of experimental villages than their counter parts of control villages. Noor and Dola (2011) concluded that training had positive impact to the farmers’ perception and performance. Sharma (2014) reported that about 15% improvement in the level of attitude of dairy farm women of Chittoor district of Andhra Pradesh towards the scientific dairy farming was due to training and other extension program. Assessment of impact of extension interventions on adoption of scientific dairy farming practices Five pillars of scientific dairy farming viz. breeding, feeding, management, disease control, and marketing were included in assessment of adoption of scientific dairy farming practices. Table 4 clearly depicted that adoption of breeding practices by the beneficiary farmers of experimental villages was significantly (p < 0.01) higher than the non-beneficiary farmers of control villages. One of the major activities of the Dairy Vikash Kendra was to provide AI facility to the villagers. Table 3 Assessment of impact of extension interventions on attitude towards adoption of scientific dairy farming practices (Mean ± SE) Experimental villages (n = 60) Control villages (n = 60) Man Whitney U Statistics Control villages (n = 60) U Statistics Z value P Value 31.93 ± 0.35 28.77 ± 0.39 766.50 −5.46 0.000 Therefore, ERS of ICAR-NDRI extended AI facility round the clock to the dairy farmers of experimental villages. This may be the reason of higher level of adoption of scientific breeding practices in experimental villages than the control villages. Data portrayed in the Table 4 clearly mentioned that mean scores of adoption regarding feeding practices of dairy animals of beneficiary farmers and non-beneficiary farmers were 5.27 ± 0.19 and 4.20 ± 0.12, respectively. This result also explained that dairy farmers of experimental villages were significantly (p < 0.01) ahead in adoption of the scientific feeding practices of dairy animal than the non-beneficiary of control villages. A critical look on the Table 1 clearly explained that a larger number dairy farmers benefitted through Dairy Vikash Kendra by getting mineral mixture, training and demonstration on azola, urea treatment of paddy and fodder crops. Due to these constant and regular interventions, adoption of scientific feeding practices of dairy animal was higher in experimental villages than the non-experimental villages. Sharma et al. (2014) reported a significant increase in use of mineral mixture, urea molasses block and concentrate mixture among the dairy farmers of Kapurthala district, Punjab due to increase in knowledge after getting training program. But, in case of adoption of disease control in dairy animals, there were no significant differentiation between the dairy farmers of control and experimental villages. The same table also depicts that among all the components of adoption of scientific dairy farming practices, disease control measure was least adopted by the dairy farmers of the both control and experimental villages. State animal husbandry and veterinary department widely covered vaccination of the dairy animal. Therefore, incidences of diseases of the livestock were very rare in the Nadia district of West Bengal. Hence, adoption of diseases control measure was too low. Like disease control measure, there were no significant differentiation between the dairy farmers of control and experimental villages in adoption of marketing practices. The farmers of both villages (control and experimental) used to sale milk to the milkman (Dudhia) due to absence of any other means like milk collection centre of milk cooperative society. Therefore, marketing component 646 Table 4 Assessment of impact of extension interventions on adoption of scientific dairy farming practices Trop Anim Health Prod (2017) 49:641–648 (Mean ± SE) Component of adoption Experimental villages (n = 60) Mann Whitney U Statistics U Statistics Z value P value Breeding Feeding 4.47 ± 0.23 5.27 ± 0.19 3.42 ± 0.19 4.20 ± .0.12 1217.00 1087.50 −3.23 −4.55 0.001 0.000 Management 4.65 ± 0.19 2.73 ± 0.21 751.50 −5.78 0.000 Disease control Marketing 3.95 ± 0.09 4.20 ± 0.09 3.75 ± 0.12 4.00 ± 0.00 1736.00 1650.00 −0.65 −2.27 0.415 0.057 Overall adoption 22.53 ± 0.55 18.10 ± 0.40 672.50 −5.99 0.000 of scientific dairy practices was not widely adopted by the dairy farmers of both control and experimental villages. Ellis (1992) in his famous book BAgricultural Policies in Developing Countries^ argued that during the initial stages of adoption of new technology in agriculture, essential inputs/ subsidies are justified as front up costs. Hence, providing of critical inputs in agriculture focused on promoting agricultural productivity by making adoption of new technologies which are urgently needed. Therefore, in this present study supply of essential inputs like AI facility, mineral mixture, and fodder seeds made available to the beneficiary farmers with an aim to adopt these technologies. Study also established that beneficiary farmers accepted these technologies which help them to better production and price for their farm produce. Assessment of impact of extension interventions on milk production and income from dairying As far as improvement in milk production was concerned, data portrayed in the Table 5 clearly mentioned that average milk production of dairy animals per household of beneficiary farmers and non-beneficiary farmers were 9.60 ± 0.56 litres and 7.00 ± 0.71 litres, respectively. This result proved that farmers of experimental villages had significantly (p < 0.01) more milk production of dairy animals per household than the non beneficiary farmers of control villages due to regular intervention of Dairy Vikash Kendra in experimental villages. Sharma et al. (2014) reported that the average milk production Table 5 Assessment of impact of extension interventions on production variables, i.e., milk production and income from dairying Control villages (n = 60) per animal per day increased from 6.76 to 6.93 litres among the dairy farmers of Kapurthala district, Punjab to due increase in knowledge after getting training program. Elias et al. (2013) reported that extension participation increases farm productivity by about 6% of small holder in highland of Ethiopia. Farmers of experimental villages were getting treatment, advice about health care practices for their animals as and when required from the Dairy Vikash Kendra which increased knowledge regarding scientific dairy farming practices create positive attitude towards adoption of scientific dairy farming practices, adopted more scientific dairy farming practices and ultimately increased milk production level of dairy animals. Economic benefits from any enterprise proved its efficacy and sustainability. Data presented in the Table 5 clearly explained that average monthly income from dairying of beneficiary farmers of experimental villages was significantly (p < 0.01) higher than non-beneficiary farmers of control villages due to increased in production of their dairy animals. Dairy farmers of experimental villages were getting superior germplasm through AI, free treatment, advice about health care practices, critical feed ingredients like mineral mixture, etc. for their animals from the Dairy Vikash Kendra which increased knowledge regarding scientific dairy farming practices followed by create positive attitude towards adoption of scientific dairy farming practices, adopted more scientific dairy farming practices and ultimately increased milk production level of dairy animals and finally income from dairying. Sharma et al. (2014) reported an increase in net (Mean ± SE) Production variables Milk Production (liter) Monthly Income from dairying (Rupees) (68 INR = 1 USD) Experimental villages (n = 60) Control villages (n = 60) Mann Whitney U statistics U Statistics Z value P value 9.60 ± 0.56 7.00 ± 0.71 1050 −3.947 0.000 3057 ± 207 1727 ± 221 651 −6.037 0.000 Trop Anim Health Prod (2017) 49:641–648 profit per animal per year was Rs. 2607.82 (1 USD = 68 INR) among the dairy farmers of Kapurthala district, Punjab due to reduction of cost as a result of increase in knowledge and adoption after getting training program. Rivera et al. (2001) and Anderson & Feder (2007) also reported increase in farm income due to organized efforts of extension system. Success story 1: Smt Kanika Mondal—an exemplary women dairy farmer of Muratipur village who ensured her livelihood through dairy farming Smt. Kanika Mondal, 39 years old, and had no formal schooling, is a woman dairy farmer from Muratipur, Chakdah, Nadia, West Bengal, and a beneficiary Dairy Vikash Kendra of ERS of ICAR-NDRI, Kalyani. She had no agricultural land and her major source of livelihood was dairying. She had total five dairy animals with two milch animals, one heifer and one calf on the day of data collection. She actively participated in different extension interventions from ERS, ICAR-NDRI, Kalyani like demonstration of azolla prodction, trainingcum-demonstration on urea treatment of paddy straw, field day, scientists-farmers interaction, dairy mela. She also accepted area specific mineral mixture for dairy animals and AI facilities for her animals from Dairy Vikash Kendra. She was also an active member of common interest group named Mahamaya Mahila Samiti established by ERS, ICAR-NDRI. She followed advice of balanced ration for her animals. At present milk production from her cow was 10–12 l/day/cow and earned Rs. 15,000/-monthly from her own dairy. She expressed that productivity of her animal substantially increased due to extension interventions conducted by ERS, ICAR-NDRI as well as Dairy Vikash Kendra and made her dairy profitable. She also requested to the scientists of ERS of ICAR-NDRI to help her to enlarge her dairy to ensure better livelihood of her chlidren. Success story 2: Shri Mritunjoy Mondal—a successful dairy farmer from Dakkhin Chandamari village Shri Mritunjoy Mondal, 60 year old, is a dairy farmer of from Dakkhin Chandamari village of Chakdah community development block of Nadia district of West Bengal. His major source of income is crop farming and dairying. He had a herd size of seven dairy animals with four milch cows and producing 10–15 l/day/animal on the day of data collection. Shri Mondal took active participation in frontline fodder demonstration, training in vermi compost preparation, training on clean milk production and demonstration of azolla prodction, training-cum-demonstration on urea treatment of paddy straw organized by ERS, ICAR-NDRI. He also actively engaged in animal health-cum-extension camps oragised for deworming, vaccination and routine treatment of animal. He was also provided fodder seed and mineral mixture. Shri Mondal adopted 647 vermi compost in his premises and cultivate fodder crops like maize, sorghum, barseem in his own field. He also availed AI facility of Dairy Vikash Kendra. He informed that his net profit from his dairying was Rs. 70,000/-during the last year which has been substantially increased due to extension interventions of ERS of ICAR-NDRI. He expressed his sincere thanks to ERS of ICAR-NDRI for opening Dairy Vikash Kendra in his nearby village and for conducting several extension program in his village which helped and encouraged him to be a successful dairy farmer. Conclusions Findings of the study manifest the impact of extension interventions in improving knowledge, attitude, adoption of scientific dairy farming practices, milk production, and income from dairying which ultimately leads to the improvement of livelihood of rural dairy farmers of Nadia district of West Bengal. It is evident that there was a significant difference between the beneficiaries (who received facilities through extension interventions for dairy farming) and non-beneficiaries (dairy farmers of control villages) in all aspects of scientific dairy farming practices. Therefore, it may be concluded that systematic extension intervention may not be a panacea to eradicate poverty from rural livelihood, but, may be a strongest weapon for improving livelihood of millions of rural masses throughout the world.
