| Abstract: |
| Genetic parameters for some reproduction traits of Adani and Adani- Alpine crossbred goats were estimated. Reproduction traits were litter size and total weight of kids for each doe at birth and weaning. Heritability estimate for litter size at birth for Adani were 0.21 and 0.35 and for crossbred were 0.31 and 0.37 in first and second parity respectively. Heritability estimate for litter size at weaning for Adani were0.22 and 0.34 and for crossbred were 0.25 and 0.34 respectively. Also, Heritability estimate for total birth weights for Adani were 0.27 and 0.48 and for crossbred were 0.25 and 0.49 and for total weaning weights for Adani were 0.12 and 0.24 and for crossbred were 0.13 and 0.27 respectively. To determine of the best contribution crossbreeding, purebred Adani and Adani-Alpine crossbreds in 3 groups include, under 50, 50 and upper 50 percent were studied. The mixed model and least square means were used for analysis. Result showed that for both parity, there is no significant different between groups for litter size at birth and weaning time. Total birth weights and weaning weights increased as Alpine contribution was increased, and highest for upper 50. Least square means of total birth and weaning weights for Adani is smaller than crossbred. For both parity, different between Adani with 50 and upper 50 crossbred was significant. This result showed that crossbreeding between Adani and Alpine goats leads to increasing of total weight of kids for each doe, but has no significant effect on litter size. |
