| 摘 要： | 对白天放牧,晚上补饲的24月龄成年龙陵黄山羊的屠宰性能及肉质理化特性进行研究。6头龙陵黄山羊用于试验,所有试验山羊14日龄去势,90日龄断奶。断奶后采用“白天放牧、晚上补饲”的半放牧饲养方式,补充饲料粗蛋白18.5%,代谢能12.5 MJ/kg。饲养至24月龄屠宰,测定屠宰性能和背最长肌理化特性。屠宰性能试验结果显示,宰前活重、胴体重、净肉重、屠宰率和净肉率分别为38.13 kg,21.15 kg,15.67 kg,55.46％和41.10％。背最长肌的理化特性结果显示,粗水分、粗蛋白、粗脂肪、粗灰分的百分含量和pH值分别为75.04％,20.99％,2.86％,0.97％,6.42。试验结果显示,成年龙陵黄山羊在较大月龄（24月龄）有较高的产肉量,肉质的各项理化指标均在正常范围内。

| Abstract: | The slaughtering characteristics and physicochemical properties of Longissimus dorsi of 24-month-old Longling goats were studied in this paper. Six newborn lambs were used as the experimental samples. They were castrated at the age of 2 weeks and weaned at the age of 90 days. After weaned, they grazed on the pasture by day and were supplied with the forage containing 18.5% crude protein and 12.5 MJ/kg metabolic energies by night until 24 months old. They were slaughtered to determine the slaughtering characteristics and physicochemical properties of Longissimus dorsi. Pre-slaughter weight, carcass weight, lean meat, dressing percentage, and lean percentage were 38.13 kg, 21.15 kg, 15.67 kg, 55.46%, 41.10%, respectively. The contents of crude moisture, crude protein, crude fat, and ash of Longissimus dorsi were 75.04%, 20.99%, 2.86%, and 0.97% and the pH value of Longissimus dorsi was 6.42. The results showed that the meat yield and quality of 24 month Long-ling goat was excellent. |
