Indigenous chicken production system in different agro-ecology of Indian Himalayan Region: implication on food and economic security.

The indigenous chicken production system (ICPS) has several use values and ecosystem services. In the last few years, ICPS has been recognized for its possible contribution to household food security, income generation, wildlife protection, and bettering the women's lives. This study aimed to collect, for the first time, comprehensive information about ICPS in three different agro-ecologies (tropical, sub-tropical, and sub-temperate) of the Indian Himalayan Region (IHR) and its role in food and economic security of traditional communities. In this study region, ICPS is semi-extensive, providing homegrown feed and temporary night shelter. In sub-temperate agro-ecology, females owned non-significant (p = 0.170) more indigenous chicken flocks than males. Households in sub-temperate agro-ecologies had significantly (p ≤ 0.001) larger flock sizes and tropical livestock units (chicken-TLU). However, the livestock diversity index (LDI) was significantly higher (p ≤ 0.001) in tropical and subtropical agro-ecology. The households in the sub-temperate region highly (p ≤ 0.001) valued indigenous chicken because of its survivability and adaptability. In absolute numbers significant (p ≤ 0.001) higher numbers of adult birds died in past 1 year in sub-temperate agro-ecology. The mortality rate of adult birds in sub-temperate agro-ecology was 9%, and it was 14 and 15% in tropical and sub-tropical agro-ecologies, respectively. In sub-temperate agro-ecology, larger flock size translated into significantly higher (p ≤ 0.001) egg production and subsequently a significant (p ≤ 0.001) higher egg consumption per household per month. In sub-temperate agro-ecology, households' dietary diversity score was significantly (p ≤ 0.001) higher. Similarly, the average annual income from ICPS was significantly higher (p ≤ 0.001) in sub-temperate agro-ecology and accounted for 18% of household income. ICPS' marketing chain was relatively short in the sub-temperate region. In all agro-ecologies, indigenous chicken and egg demand was significantly higher (p ≤ 0.001) in the winter. ICPS litter is used as farmyard manure, enhancing ecological resilience. In all agro-ecologies, the three most frequently cited obstacles to extending the indigenous chicken production system are illnesses, predators, and a lack of chicks availability. ICPS contributes to food and nutritional security, economic stability, and ecological resilience in this hilly and fragile ecosystem. Even though the system is self-sustaining, management and health interventions can increase production and productivity.

Participatory assessment of management and biosecurity practices of smallholder pig farms in North East India.

The present study was aimed at describing the pig production system, farm management, pig movement, and existing biosecurity level of smallholders' pig production system in North East India. A cross-sectional survey of 1,000 pig producers in four districts (two urban and two rural) in core pig-producing regions of India, where ASF occurrence had been reported, was conducted. The mean pig population was significantly (p < 0.05) higher in urban districts. In urban districts, most of the pig houses were isolated but located on the roadside, while in rural districts, commune pig houses along the roadside were more common. The majority of the respondent purchased (91%) or sold (60%) the pigs during the past 12 months. Swill feeding was common in the entire study area. The majority of the respondent (80%) in rural districts were unaware of ASF. Significant pig trade of live pigs and pork products was observed in the urban district. In the case of on-farm biosecurity measures, only 6.9% of respondents had fencing for the pig farm, 99.3% did not have provision for a footbath, and only 17.2% of the respondents restricted visitors' access to the pig farm. The study revealed that the pig production system is dominated by smallholding units with a frequent introduction or exit of pigs along with poor on-farm biosecurity measures. With the current level of farm management and biosecurity practices, smallholder pig farmers are at an increased risk of ASF and other contagious diseases.

Performance evaluation of the parents of the improved backyard poultry germplasm in sub-tropical condition of North Eastern Hill Region of India.

Productivity of traditional backyard poultry in developing countries can be enhanced by introduction of improved germplasm of backyard chicken which is adaptable to diverse ago-climatic condition. The growth and reproductive performance of parents of improved backyard chicken (Vanaraja and Srinidhi) were evaluated under intensive production system in humid sub-tropical region of North East India. We also evaluated the growth performance and mortality in terminal crosses of above parents until 6 weeks of age. At day 0 and at 25 weeks of age, body weight of Srinidhi male parent was significantly (P<0.05) higher than Vanaraja male parent. During brooding stage, mortality was 15.7% in Srinidhi male parent, 14.5% in Vanaraja male parent, 13.9% in Srinidhi female parent, and 8% in Vanaraja female parent. Hen-day egg production (HDEP) of Vanaraja female parent varied from 0.2 at 25 weeks to 54.9% at 54th weeks of age. In Srinidhi female parent, HDEP reached 60% at 35 weeks and peaked 63.9% at 39 weeks of age. Srinidhi female parent has significantly (P<0.05) lower age at first lay. Average annual egg production was significantly (P<0.05) higher in Srinidhi female parent (202 eggs vs. 137 eggs). Egg weight at 25, 30, 35, 40, 45, and 50 week of age was significantly (P<0.05) higher in Vanaraja female parent. Egg shape index and yolk index at 40 weeks of age were significantly (P<0.05) higher in Srinidhi female parent. Fertility of Vanaraja female parent was significantly (P<0.05) lower in winter. In case of Srinidhi female parent, fertility was significantly higher (P<0.05) in winter as compared to summer. In case of terminal crosses, body weight at 6 weeks of age was significantly (P<0.05) higher in Vanaraja as compared to Srinidhi. Cumulative mortality during brooding phase was 9.2 per cent in Vanaraja and 9.6 per cent in Srinidhi. In conclusion, parents of Vanaraja and Srinidhi are suitable and well-adapted birds in humid sub-tropical condition of North East India. These birds could be introduced in the region on large scale for up-scaling of traditional backyard poultry.
