A study was carried out to compare and estimate the effect of non-genetic factors (location, parity and color) on the productive and reproductive performance of Hill goats (Khari) representing Nawalparasi, Dhading and Syangja districts from the farmer’s managed conditions from February 2014 to September 2014. Altogether, 40 does and their respective immediate kids (47) from Nawalparasi, 30 does and their respective immediate kids (53) from Syangja and 20 does and their respective immediate kids (32) from Dhading district were taken for the purpose of study. The data were analyzed using the Harvey (1990) computer software package. Least square mean comparison was made by using Duncan Multiple Range Test (DMRT). The findings revealed that goats in Syangja had shorter days of age at first conception (229.37±days), age at first kidding (380.57± days), kidding interval (253.93± days) and post partum estrus (89.19±9.60 days) than in the dams of Dhading and Nawalparasi district. Kidding rate was higher (1.77±0.06) in Syangja district with respect to the kidding rate observed in case of Dhading and Nawalparasi districts. Reproductive traits that were significantly influenced by location were age at first conception (P<0.05), age at first kidding (P<0.05), kidding interval (P<0.05) and post partum estrus (P<0.05). Kidding rate was significantly influenced by both location (P<0.001) and parity (P<0.001) too. Litter size at birth and weaning were significantly (P<0.001) influenced by location and parity whereas litter weight at birth was significantly influenced by location (P<0.001) and parity (p<0.05) and litter weight at weaning was significantly (P<0.001) influenced by both location and parity. So, it can be concluded that, the dams of Syangja were superior in terms of all reproductive traits taken into consideration along with kidding rate and litter traits too.
