Understanding the unique traits of indigenous pigs which make them resilient to climate change and development of data base

The performance of various breeds of pig in different housing models was tested under Meghalaya conditions. The study revealed that the growth rate in deep litter housing was better and there was lower incidence of diseases and occurrence of other abnormal behavior. Comparison of physiological parameters in different pig housing models revealed that under concrete floor, respiration rate, pulse rate and body temperature was higher by 11, 4.9, 0.39% in summer and 28, 3.9, 0.47% in winter, respectively compared to deep litter housing system. Under Sikkim conditions, growth performances of Local/Lepcha and Hampshire pig breeds were found better under deep litter condition as compared to concrete floor pig pen. Morphometrically, the small snout length of indigenous pig makes it more suitable for deep litter housing system as they dig less when compared with other breeds.

An experiment on formulation of fortified feed from kitchen waste for pig revealed that the group which was fed with 7% molasses had better growth rate (280 g/d) as compared to control group (230g/d) and molasses may help in protecting the animals from climatic stress.

Identification of the unique traits in indigenous pigs which make them resilient to climate change was done in Basar centre. The unique traits identified in the local breed of pig of Arunachal Pradesh are long bristle length (4-9 cm) and potbelly. Long hair bristles act as insulator during cold season and are shed during summer season. Similarly, potbellied condition may aid in better dissipation of heat during high temperature.


Hampshire x Yorkshire crossbred and Mizo local pigs (Zovawk) were evaluated in different altitudes under farmer’s field conditions in Mizoram. Studies revealed that crossbred pigs have the greatest potential for their use as improver breed for meat and litter size as compared to local pigs. The average body weight at birth and weaning was found to be 1.52 kg, 8.12 kg in crossbreds and 0.512 kg and 4.21 kg in local pigs. The average litter size at birth (8-12) and litter size at weaning (8-9) was higher in crossbred pigs than that of local pigs (4-6). The results of crossbred pigs in farmers’ field showed substantial improvement in body weight at slaughter and feed conversion efficiency. The optimum level of exotic inheritance in crossbred ranges from 50-87.5% and has been found to be suitable for subtropical humid condition of tribal hill regions of Mizoram. The farmers experienced a positive impact on the pork productivity and income. The overall livestock cropping intensity was enhanced to the extent of 80-85%.
