Study on reproductive performance of Nellore Jodipi sheep in RKVY and non-RKVY flocks under field conditions

Abstract

A study was conducted to evaluate the reproductive performance of Nellore Jodipi sheep, native sheep breed of Andhra Pradesh in RKVY and Non-RKVY flocks of farmers in Andhra Pradesh. The data on reproductive traits viz., age at first mating, age at first lambing, service period, lambing interval were acquired from the sheep farmers via structured questionnaire. Twenty-eight farmers were interviewed in order to obtain information on sheep breeding operations and reproductive performance in their flocks. The overall least squares mean for age at first mating in rams, age at first mating in ewes, age at first lambing, service period and lambing interval were 584.17 ± 4.92, 643.34 ± 6.11, 837.95 ± 4.70, 162.78 ± 1.54 and 408.93 ± 7.67 days, respectively.
