Abstract

The present research was conducted to investigate the effect of sex and age of goats on live weight, hot carcass weight, dressing percentage, chemical composition and pH of meat obtained from Black Bengal goat. Fifty goats of different age (up to 3 years) and sex groups (buck, castrated male, doe and kids) were slaughtered. After pre-slaughter weighing goats were sacrificed using the approved “Halal” method. The average live weight of doe up to one, two and three years of age were 12.51, 14.35 and 16.35 kg and of buck were 10.57, 19.29 and 37.05 kg, respectively. There were significant differences between the live weight of doe and buck at different age group. Hot carcass weight of doe and buck differ significantly among the different age group also differ significantly between the different sex group’s goat. The mean hot carcass weight of castrated male at one year of age was 7.82 kg and was observed highest in castrated male than doe and buck. The average dressing percentage of doe, buck and castrated male at one year of age was 42.02, 39.01 and 43.56%, respectively but the values did not differ significantly. There were no significant differences of DM, moisture and CP content between doe and buck at different age group but significant differences were observed among the different age group of doe and buck. Fat content was significantly different among the different age group of doe and buck. There was significant difference of ash among the different age group of doe and buck. The pH values of goat meat did not differ significantly among the different age and sex of goats. From this study, it was concluded that the meat quantity in terms of hot carcass weight and dressing percentage were higher when castrated male slaughter within one year whereas maximum hot carcass weight was obtained when buck slaughter at the age 2-3 years and meat quality in terms of crude protein content was higher in meat obtained from buck and ether extract content was lower in buck meat when slaughter within one year.

年龄和性别对黑孟加拉山羊肉质和肉量的影响

本试验旨在研究山羊性别和年龄对黑孟加拉山羊肉品质的活重、热胴体重、屠宰率、化学成分和pH值的影响。宰杀了50只不同年龄(3岁以下)和性别群体(公山羊、阉割公山羊、母山羊和小山羊)的山羊。屠宰前称重山羊后，使用经批准的“清真”方法进行屠宰。母鹿1岁、2岁和3岁的平均活重分别为12.51、14.35和16.35 kg，雄鹿10.57、19.29和37.05 kg。不同年龄组雌鹿和雄鹿的活重差异显著。母鹿和雄鹿的热胴体重在不同年龄组之间差异显著，不同性别组的山羊之间差异显著。1龄阉公平均胴体热重为7.82 kg，阉公高于母鹿和雄鹿。1岁雌、公、去势公的平均屠宰率分别为42.02、39.01和43.56%，但差异不显著。不同年龄组的母鹿和雄鹿的干物质、水分和粗蛋白质含量差异不显著，但不同年龄组的母鹿和雄鹿之间存在显著差异。不同年龄组雌、雄鹿脂肪含量差异显著。灰分在母鹿和雄鹿不同年龄组间存在显著差异。不同年龄、性别的山羊肉质pH值差异不显著。本研究得出:1年内屠宰去势公羊的热胴体重肉量和屠宰率较高，2 ~ 3岁屠宰雄鹿的热胴体重肉量最大，1年内屠宰雄鹿肉的粗蛋白质含量较高，粗脂肪含量较低。爆炸。j .似的。科学通报，2016。45 (1): 19 - 24
