Inheritance of Wattle and Their Effect on Twining and Some Productive Traits in Shami Goat

Data were obtained from Shami goat including bucks, does and their kids that bred at Shami Breeding Station/ Qushtapa-Erbil, during Sep. 2012 – March 2013. Ninety five kids resulted from six sires and sixty one does were used in this study. Presence or absence of wattles, type of birth of kids, milk yield of does as well body weight of kids at birth, weaning and at six month of age were recorded. General linear model procedure used to investigate the effect of wattle appearance on milk yield of does as well on body weights of kids. The appearance of wattle and their relationship with type of birth were analyzed by Chi-Square. Gene frequency was also calculated. The results revealed that the sires were all heterozygotes for the wattle appearance trait. Two of the used does were dominant homozygotes, while twelve of them were recessive homozygotes, and eight were heterozygotes for the appearance of wattle. The gene frequency p and q for the kids were (0.5) for both of them. Recessive kids (ww) resulted by mating sire with wattle with does without wattle were (21) kids (male and female) and the percentage was 1:2, which indicate that the appearance of wattle not related with sex. Total milk yield was 267.728 kg in both does with wattle and without wattle. Does with wattle yielded significantly higher milk (289.920) kg than those without wattle (225.457). Body weights of kids at birth, weaning and at six month of age were 4.059, 16.320 and 35.455 kg, respectively. The body weight at birth and weaning were significantly influenced (P<0.05) by wattle incidence, where the kids with wattles have higher body weights comparing with kids without wattles. Although kids with wattles excelled those without wattles in their body weight at six month of age, but the differences were not significant. Does with wattle produced significantly higher twins comparing with does without wattles (x2=27.905; p<0.001). It was concluded that does with wattles produce higher milk as well they were more fertile because they produce higher twins. Kids with wattles have higher body weights at all ages. So the breeders advised to bred bucks and does with wattles in order to increase the productivity of their flocks. Keywords— Shami Goat, Wattle, Milk Yield, Body Weight.
