摘要: 【目的】为探讨年龄因素对槐山羊产肉性能及肌肉品质的影响;【方法】选择不同月龄槐山羊进行屠宰性能测定,对其胴体性状、胴体分割质量指标、胴体理化性质进行了研究;【结果】4月龄、8~10月龄、16~18月龄槐山羊的屠宰率分别为44.03%、48.09%、48.15%,净肉率分别为29.24%、32.21%、31.22%,以8~10月龄槐山羊三级肉所占的比例最小;粗脂肪含量随月龄的增加而显著增加;不同月龄之间,熟肉率(%)、失水率(%)、pH 值均变化不大,而眼肌面积、肌纤维直径、剪切力随着月龄的增加而增加;【结论】综合以上测定结果,3个年龄组中以8~10月龄槐山羊屠宰性能及肉用品质最好

Abstract: 【Objective】The objective of this study is to study effect of different age on the meat production and quality of Henan Huai goat; 【Method】Henan huai goats are slaughtered at 3 age groups;【Results】The results show as follow :The dressing percentage of Henan Huai goat at 3 age groups is respectively 44.03%(4month), 48.09%(8~10 month), 48.15%(16~18month). The net meat percentage at 3 age groups is respectively 29.24% (4month) ,32.21% (8~10month), 31.22% (16~18month). The content of crude fat increases significantly with age. There are no difference (P > 0. 05) at 3 age groups in some physical traits , such as cooked meat ratio, water-lossing, PH. However,the rib eye area ,cutting , diameter of muscle fiber increases significantly with age;【Conclusion】Meat Production and quality of 8~10 month Henan huai goat are the best at 3 age groups
