Abstract

In this study, the performance of pure and crossbreed of Lori-bakhtiyari sheep was investigated. Data related to natives were collected during 1989 to 2018 and data related to crossbreed during 2011 to 2019 were collected at Sholi station in Shahrekurd. Conception rate at lambing was 87.5% for crossbreed sheep and 86.56% for Lori-bakhtiyari sheep. Litter Size% obtained 138.22 and 114.6 for crossbreed and Lori-bakhtiyari sheep respectively. Lambing percentage obtained 120.95 and 99 for crossbreed and Lori-bakhtiyari sheep, respectively. Fecundity (produced by a ewe) for crossbreed was 1.38 and 1.15 for Lori-bakhtiyari sheep. The weaning percentage for crossbreed and Lori-bakhtiyari sheep estimated 109.49 and 90.99 respectively. Survival rate estimated 90.5% and 91.7% for crossbreed and Lori-bakhtiyari sheep, respectively. Weaning weight per kg Weight of ewes was calculated 0.593 kg for native lambs and 0.610 kg for crossbreeds, this difference was statistically significant. According to the obtained results, use of genetic production method in Lori-bakhtiyari flock led to an increase in per capita profit of each crossbreed ewes of 4286000 R compared to native ewes in 2019. This amount was calculated for crossbreed ewes after second calving 4886480 R compared to native ewes.
