| Abstract |
| Genetic parameters for body weights of purebred and crossbred Adani goats were estimated by multiple traits model with maternal additive genetic and permanent environment. Heritability estimates for body weights ranged from 0.23 to 0.37 and were the highest in the end of growth period. Direct additive genetic correlation between body weights ranged from 0.19 to 0.96. Maternal additive genetic correlation between body weights ranged from 0.41 to 0.94. Genetic correlations between adjacent records were high and decreased as the interval between them increased. To determine of the best contribution between Adani and Alpnie in crossbreeding, body weights, daily gain, feed intake and feed conversion ratio (FCR) for purebred Adani goats and Adani-Alpine crossbreds in 4 groups include, under 50, 50, 68.5 and 75 percent were studied. For study of growth trend and feed intake, from each genetic group, 5 head kids selected and were housed in individual pens and were fed ad libitum. For 6th to 9th month of growth period, feed intake was recorded and kids were weighed weekly. The mixed model and least square means were used for this analysis. Result showed that body weights, daily gain and feed intake increased as Alpine contribution was increased, although this is not always significant. For least square means of FCR, no significant differences were observed between genetic groups. This result showed that determine of the best contribution between Adani and Alpnie in crossbreeding, it depends on the availability of food sources. |
