Performance of Doom pigs under different production systems in subtropical ecosystem of north east India

Doom pig is a newly registered indigenous breed from subtropical ecosystem of north east India. This breed adapt well to the harsh agro-climatic condition with minimum input. The population of this pig breed showed a declining trend, mainly due to high rate of crossbreeding, lack of breeding policy and lacunae in production system. Under field condition, the farmers follow two different types of production systems, viz. migratory scavenging and backyard production system. Doom pigs reared under backyard production system has higher growth performance and carcass yield. However, pigs in migratory scavenging system have better reproductive efficiency and quality pork yield. Therefore, it can be concluded from the present study that backyard production system is more suitable for fattener pig production and migratory scavenging system for breeding pig production. The results from this study can be suitably exploited to design conservation and breeding strategies for newly registered Doom pigs of north east India.
