Feedlot and carcass studies on Sirohi, Marwari and Kutchi kids with economics of production under intensive system of management

Data pertaining to 63 male kids belonging to Sirohi, Marwari and Kutchi goa t breeds under feedlot experiment (for a period of 3-12 months of age), pla nned in intensive system of management during 1992-93 with a ration consist ing of concentrate and roughage in a ratio of 60: 40 revealed that initial body weights (at 3 months of age) were 15.70+/-0.51 (Sirohi), 14.56+/-0.32 (Marwari) and 14.00+/-0.58 kg (Kutchi). The final live body weights (at 9 m onths) at slaughter age were 37.33+/-1.17 (Sirohi), 34.81+/-0.47 (Marwari) and 32.76+/-1.44 kg (Kutchi). The live body weights at 12 months of age for rest of the kids were 45.15+/-1.02 (Sirohi), 41.25+/-0.72 (Marwari) and 40 .38+/-1.54 kg (Kutchi). The ranges for average daily gains during phase-1 ( 3-6 months), 2 (6-9 months) and 3 (9-12 months) were 106 (Kutchi) to 134.09 g (Marwari), 90.45 (Marwari) to 115.9 g (Sirohi) and 65.83 (Kutchi) to 80. 7 g (Sirohi), respectively. Ranges for dry matter intake/kg live body weigh t gain during phases-1, 2, 3 and 4 were 6.19 (Marwari) to 7.29 kg (Kutchi); 9.36 (Kutchi) to 10.64 kg (Marwari); 14.41 (Sirohi) to 16.83 kg (Marwari) and 8.90 (Kutchi) to 9.52 kg (Marwari) respectively. Slaughter studies indi cated that dressing percentages on the basis of pre-slaughter weights were 48.91 (Sirohi), 48.46 (Marwari) and 52.06% (Kutchi). Other carcass traits a nd economics of meat production were also studied and reported in the text.
