- •
Olkuska sheep population is characterized by high levels of inbreeding, which is highly differentiated between single flocks, and small number of founders.
- •
Inbreeding effects on birth weight, weaning weight (at 56 days of age), lamb survival up to 56 days and the litter size of ewes were evaluated.
- •
Significant inbreeding depression in lamb body weight and survival up to 56 day was found.
- •
No significant inbreeding effect on litter size confirms the hypothesis that the effect of single gene is greater than any effect of inbreeding.
