| Popis: | This study was conducted to evaluate the growth performance and survival rate of Boer x Central Highland goats. Data collected under field condition were utilized for this study. The overall least squares mean for birth weight (BWT), weaning weight (3MWT), six-month weight (6MWT), weight gain from birth to weaning (ADG1) and weight gain from weaning to six months of age (ADG2) for Boer crossbred goats were 2.73 kg, 10.4 kg, 14.5 kg, 84.4 g day-1 and 49.4 g day-1 , respectively. Whereas the overall least squares mean BWT, 3MWT, 6MWT, ADG1 and ADG2 for Central Highland goats were 1.79 kg, 6.77 kg, 10.6 kg, 54.1 g day-1 and 50.4 g day-1 , respectively. Sex, birth type and year of birth were the major determinants for growth traits. The pre-weaning survival rate of crossbred goats was 81.7%. The overall mean litter size at birth, litter size at weaning and weaning rate for Central Highland does were 1.48 kids, 1.21 kids, 81.7%, respectively. The pre-weaning growth performance of Boer crossbreds was superior to the indigenous Central Highland goats. However, the post-weaning growth rate was found to be similar for both genotypes. Central Highland goat had a moderate prolificacy and mothering ability. |
