Abstract
Evaluation of kid growth characteristics and doe productivity was observed from Sapera (Local PExSaanen) dairy goat. Birth weight (BW), weaning weight (WW), and average daily gain (ADG) of 151 kids were analyzed for the effects of sex, birth type, parity, kidding season, and kidding year using the General Linear Model (GLM), while heritability values were estimated by the paternal half-sib correlation method. The Doe Productivity index (DPI) of 77 does was calculated by the equation DPI =(12/KI)(LS)(Body Weight). The averages of BW, WW, and ADG were sequentially at 2.94 kg, 9.70 kg, and 0.075 kg. BW was influenced by sex (P<0.01), birth type (P<0.01), and parity (P<0.05)- WW was significantly influenced (P<0.05) by parity and kidding season, while ADG was not significantly (P>0.05) affected by the environment. The heritability values for BW, WW, and ADG were respectively h2 = 0.289, 0.239, and 0.065. Based on parity 1 to 5, averages of kidding interval were 297 - 307 d, while the reproductive rates of the does at birth was 2.04 - 2.55 kids/doe/year and at weaning 1.68 - 2.12 kids/doe/year. Further, DPI was obtained at the birth of 10.89 - 16.57 kg and the weaning of 23.84 - 43.43 kg. It was concluded that kid body weight was quite large influenced by genetic factors with DPI being quite high in Sapera cross-dairy goats
