摘要
对不同月龄的龙陵黄山羊进行了胴体和肉质理化特性的分析测定，结果得出，８月龄和１８月龄龙陵黄山羊屠宰率和净肉率分别为４５．５２％±３．４９，３２．６２％±０．６４和４８．５１％±１．７２，３７．５１％±０．５２，显示出良好的胴体品质。不同月龄间羊肉的水分、干物质、肌间脂肪含量和肉色差异显著（Ｐ＜０．０５）．背最长肌肌纤维直径分别为５７．１２μｍ和６２．８７μｍ。蛋白质中赖氨酸和组氨酸的含量丰富，８月龄占羊肉蛋白质７．７３％±０．５１和２．５６％±０．２９，１８月龄占羊肉蛋白质８．１６％±０．３８和２．８５％±０．１２均高于理想蛋白中的含量．
The carcass composition and the meat quality of LongLing Red Goat at ageof 8 months and 18 months were determined.The result shows that the dressing percen-tage and the meat percentage were 45.52%±3.94 and 32.620%±2.64,48.5l%±1.72 and37.55%±0.52 respectively.These facts show that LongLing Red Goat have good car-cass composition. Moisture,dry matter,fat in mutton and colour of mutton havesignifeant difference between 8 months old group and 1 8 months old group(P<0.05 ).The flber diameters of longissimus muscle were 57.12±6.55μm and 62.87±4.17μm,respectively.protein in mutton contain a large amount of Lysine and histidine. lysine andhistidine content in protein ofmutton of8 months and 18 months old were 7.73%±0.51and 2.56%±0.29,8.16%±038 and 2.85%±0.12 respectively those ofall trail goats arehigher than those of idea protein.
