Abstract
This research was carried out in order to determine some reproductive traits, the birth and the weaning weight and daily live weight gain of Morkaraman sheep in different farms of Mus province. The data used in this study was one year data of 2019 year obtained from a total of 28 sheep farms in Mus province. The mean for birth weight and 90th day weaning weight were calculated as 3.79±0.01 and 29.30±0.10 kg. The average daily live weight gain of lambs was found 272.8±0.01 g between birth and 90th day. Means for some reproductive traits as lambing rate, infertility rate, survival rate at 90th day weaaning, fecundity, and litter size were found as 92.2%, 7.8%, 97%, 1.11, and 1.21, respectively. Effect of birth type and dam age on birth and weaning weight and daily live weight gain was found to be statistically significant (p<0.001). Effect of gender on birth (p<0.001) and weaning weight (p<0.05) was found to be statistically significant. The results of this research have shown that source of variation observed for birth and weaning weight in Morkaraman sheep may be the genetic and the environmental. As a result, it has been recommended to perform the improvement studies in mutton production from Morkaraman sheep and growth features can be used as a breeding criterion to improve meat yield.
