Fifty buck kids from five goat genotypes, Boer x Angora (BA), Boer x Saanen (BS), Feral x Feral (FF), Saanen x Angora (SA) and Saanen x Feral (SF) were compared for production of Capretto and Chevon carcasses. BS and SF kids had significantly better average daily gain compared to other genotypes and took less time to reach the required liveweight for Capretto and Chevon production. The development of visceral organs was not influenced by genotype. Kids from dairy breeds (SA in case of Capretto and SF in case of the Chevon group) deposited more internal fat in comparison to other genotypes. Dressing percentage (based on empty body weight) of kids ranged from 50-55%. At the same liveweight, dressing percentage and eye muscle dimensions did not vary between genotypes. However, BS and SF kids produced longer carcasses. Subcutaneous fat thickness was significantly greater in Chevon carcasses from BA compared to other genotypes. A high correlation was found between fat thickness measured by ultrasound on the live animal and ruler measurement on the carcass at the 12/13th rib position. Based on growth and carcass characteristics BS and SF kids performed better than kids from other genotypes used in the present study.
