Evaluation of the reproductive characteristics of Sirohi goats from Udaipur India
Lokesh Gautam, Hina Ashraf Waiz and Rajendra Kumar Nagda
The data on reproductive performance of Sirohi goats maintained at AICRPon Sirohi goat at LRS, Udaipur, India, and recorded between 2004-16, were analysed to study the reproductve traits and their genetic control. The overall least squares means of AFC, AFK, KI, SP, GP and DP were 513.20±20.94, 657.20±20.48, 292.03±4.14, 142.17±4.18, 149.95±0.07 and 144.00±4.09 days, respectively while least-squares means for WFC and WFK were 27.84±0.42 and 30.57±0.40 kg, respectively. Sire and Cluster had significant effect on all reproductive traits. Period and season of birth had highly significant effect on AFK. Summer born kids had lowest kidding interval, service period and dry period as compared other season. The heritability estimates of all reproductive traits were moderate (0.13-0.38), except for gestation period, which had low heritability (0.002±0.027). The phenotypic and genetic correlations among the different reproductive traits were positive and high, except for phenotypic correlations between gestation period with kidding interval, service period and dry period which were very low.
