Smallholder pig farming is an important livelihood resource for the tribal people in Northeast India. The system of pig rearing is unique and traditional. Based on the traditional knowledge and resource availability, the farmers have evolved a feeding system for the pigs. The present study aimed to explore the traditional feeding system for pigs in Tripura, a state of Northeast India. The chemical compositions of local feed resources were done. All the feed items contained more than 85% organic matter. The main diet containing rice bran mixed with locally made rice bear waste (choak) had 11.3% crude protein. An on farm trial was conducted on eighteen healthy Hampshire crossbred female piglets at the age of 2 months old and the piglets were divided in three dietary groups to investigate the growth performances of pigs fed diet containing varying proportions of the traditionally made rice bear waste. Feeding of traditionally made rice bear waste upto 25% of total dry matter increased (P<0.05) growth rate and feed conversion efficiency in pigs as compared to the other two groups. In another study, data on growth and reproductive performances of seven pig varieties (12 female pigs for each pig variety) was collected from randomly selected 84 smallholder pig farms and analyzed by one way ANOVA with the post hoc comparisons by the Duncan multiple range test. The average body weights of female and male pigs of different pig varieties varied significantly (P<0.05) at birth, 2- month, 6- month, 1 year of age and during 1st conception. Hampshire cross pigs attained highest body weight (more than 85 kg) at 1 year of age as compared to the other pig varieties under the traditional feeding system. Indigenous Ghungroo pigs conceived at the younger age (253.64 ± 13.52 days, P<0.05) as compared to the other pig varieties. Piglet mortality ranged from 4.80 ± 7.28 to 15.47 ± 8.88% across different pig varieties (P=0.11). The present study suggested that the traditional feeding system might be utilized in an improved way for the pigs in a rural environment in Northeast India.
