Abstract:
Genetic parameters for milk yield of purebred and crossbred Adani goats were estimated. Heritability estimates of total milk yield for Adani and crossbred goats were 0.32 to 0.37 respectively. To determine of the best contribution in crossbreeding, total milk, daily milk yield, lactation period, feed intake and feed conversion ratio (FCR) for purebred Adani and crossbreds goats in 3 groups include, under 50, 50 and upper50 percent were studied. For study of daily milk yield and feed intake, from each genetic group, 5 head animals selected and were housed in individual pens and were fed ad libitum. For 5 months of lactation period, feed intake and milk yields were recorded every 15days. The mixed model and least square means were used for this analysis. Tukey test was used for the comparison between least square means of genetic groups. Result showed that average of all traits for crossbred were higher than Adani goats. The highest total milk yield, daily milk yield and feed intake belong to upper 50 percent crossbreds and the highest lactation period belong to 50 percent crossbred goats, although this is not always significant For least square means of FCR, no significant differences were observed between crossbred groups but the difference between Adani and crossbred goats was significant. This result showed that determine of the best contribution between Adani and Alpnie in crossbreeding, it depends on the availability of food sources. Depending on the circumstances, crossbreeding of 50 and upper to 75 are the best combinations
