Some carcass traits and physicochemical composition of White Improved breed goat kids slaughtered at 90 and 180 days of age (Short Communication)

摘要

The research aimed at analysing the slaughter value and physicochemical attributes ofgoat kids slaughtered at 90 and 180 days of age. After weaning at 60 days of age, abalanced mixture containing 18.2 % of protein and 5.63 MJ of net energy was applied as afeed. Some traits of live and slaughtered animal weight attributes were analysed. Moreover,tissue composition of the half carcass and meat physicochemical properties of meat weredetermined. The carcass of older male kid goats was by 5.08 kg (≤0.05) heavier and theweight of primal cuts (≤0.05) including high-priced cuts was by 0.87 kg higher than theyoung kids. Half carcass tissue composition of older and younger kids was similar: 60.13–60.50 % of meat, 25.48–25.37 % of bones, and 14.39–14.13 % of fat. Significant differences(≤0.05) in fat and bone contents were only found in the leg. Furthermore,physiochemical properties indicated that the meat of older animals was darker and hadhigher values of chemical parameters.
