Effect of Non-Genetic Factors on Litter Traits of Hurrah Pigs in Nawalparasi, Nepal

摘要

Data on litter traits of 47 Hurrah pigs of various VDCs of Nawalparasi district of Nepal over a period of July, 2011 to January 2012 constituted the material for the present study. The overall least squares means for litter size at birth (LSB), litter size at weaning (LSW), litter weight at birth (LWB) and litter weight at weaning (LWW) were 8.70±0.27, 7.53±0.20, 6.30±0.26 kg and 50.57±1.37 kg respectively. All the litter traits were found to be significantly influenced by parity of Dam (p<0.001). However, season was not found to be the important source of variation among litter traits. In general, litter traits showed increasing trend from 1~(st) to 4~(th) parity.
