Özet

The objective of this study was to estimate the effect of inbreeding on birth weight (BW), weaning weight (WW90), and lamb survival rate (LSR) in Saki{dotless}z sheep. The effect of inbreeding on BW, WW90, and LSR traits was studied by analysis of variance technique and regression method. Inbreeding had a significant effect on BW and the regression coefficient of inbreeding on BW was -0.0245±0.0076 kg (P<0.01). The mean level of inbreeding (F) of all animals overall years was 2.25% for lambs. The inbred lambs rate was 17.7%. The coefficient of inbreeding ranged from 6.25% to 25.0% and average was 12.68% for birth weight in inbred lambs. Inbreeding weren't a significant effect on weaning weight at 90 days of age and lamb survival rate. It was concluded that inbreeding showed deleterious effects on birth weight and had a no effect on lamb's weaning weight and survival rate.
