Effect of Castration Methods on Growth Performance and Carcass Composition of Crossbred (Black Bengal x Saanen) Male Goats
Keywords:

The aim of this experiment was to study effect of castration methods on growth performance and carcass composition of 20 male crossbred (Black Bengal x Saanen) goats. They were randomly divided into 4 groups with 5 replications each according to completely randomized design. The experimental groups were intact male (control; treatment 1), injected progesterone hormone (treatment 2), castrated with Burdizzo (treatment 3) and surgical castration (treatment 4). The experimental period was 16 weeks. The results revealed that the castrated with various methods groups had average daily gain (P<0.01), dry matter feed intake (P<0.01), feed cost/1 kg gain (P<0.01), feed intake/1 kg gain (P<0.05), and feed cost/1 kg gain (P<0.05) significantly better than the intact male group. The castrated goats had significant higher visceral fat than intact male group (P<0.01). However, there were no significant difference among intact (non-castrated) and castrated male goats on slaughter weight, hot carcass weight, dressing percentage, meat and bone percentages.
