STUDY THE PRODUCTION PERFORMANCE OF KARAKOL AND LOCAL SHEEP UNDER THE SYSTEM OF REPEATED BIRTHS

This study was applied in Al-Kafil Station located in Karbala Governorate, located 13 Kgm south of Karbala City, for the period from May 15, 2021 to August 15, 2022. It included different ages and weights: 20 sheep from Karakol and local sheep. The aim is to study the effect of the genetic group (strain) and some non-genetic factors such as age and weight, gender of the newborn, type of birth and season of birth on birth weight and weaning. And the average of the daily weight gain as well as the estimation of the daily and total milk production of the sheep Also, the study of the effect of genetic and non-genetic factors mentioned earlier on the survival rate of lambs from birth to weaning and the results of the study are as follows. The results showed a significant effect (P-0.01) on birth weight and (P-0.01) on weaning weight and daily weight gain, where the Karakol group was superior to the two strains in birth weight, weight and daily weight gain, reaching 4.55, 23.12, and 0.207 Kg respectively. Age, birth weight and season of birth have been recorded a significant effect on birth weight, weaning weight and daily weight gain, where sheep aged four years and more and in the weight category of 50 kg or more have the best performance, while the type of birth has no significant effect on birth weight, weaning weight and daily weight gain. The general average for daily and total milk production was 0.459 kg/day, 55.16 kg/day, respectively. It is clear that the sex of the sheep has a significant effect (P-0.05) on the daily and total milk production, where male-born ewes achieve more than female sheep.
