【摘要】 试验选用4,5,6,8月龄巴寒F2肉羊的股二头肌、背最长肌和臂三头肌为试验肉样,通过测定其常规理化指标(水分、灰分、粗蛋白和粗脂肪)来分析研究不同月龄巴寒肉羊的不同部位营养品质变化情况。结果表明,整体来看,巴寒F2肉羊背最长肌(B)的水分含量高于臂三头肌(L)和股二头肌(G),其股二头肌相对其他两个部位的肌内脂肪含量最少,且6月龄成为巴寒肉羊水分和脂肪含量先增长后减小的拐点;而灰分和蛋白质均随着月龄的变化处于不断增加的趋势。更多还原

【Abstract】 The stock two myo, longissimus muscle and triceps muscle of arm of 4, 5, 6, 8 months Bahan F2 sheep were selected as test samples, by measuring its regular physicochemical indexes(moisture, ash, crude protein and crude fat), to analyze the changes of the nutritional quality of the different parts. The results showed that the moisture content of longissimus dorsi(B) was higher than brachial triceps(L) and the stock two myo(G); compared with the other two sites, the stock two myo’s intramuscular fat was the lowest, and the June age become inflection point bar cold mutton fat and moisture content growth reduced; the ash and protein changed with age in the increasing trend.更多还原
