关中奶山羊羯羔肉用性能的初步研究

选用18只肥育后健康羯山羊,屠宰后系统测定了有关肉用性能和肉质特性指标。并用多元统计方法对指标间的相互关系作了详尽地分析。结果表明,不同体重间屠宰及胴体性状差异显著,山羊肉中胆固醇含量显著低于其他肉类,肌肉、肾脂的脂肪酸组织差异十分明显,活重与胴体重相关系数高达0.97,活体指标与胴体指标间典型相关系数也达0.96。本研究首次测定了肌肉中乳酸脱氢酶和肌酸磷酸激酶的活性。为肉质特性研究提供了参考。

The Preliminary Study of Meat Performance of Castrated Kids of Guanzhong Milk Goats

Eighteen castrated kids of Ganzhong milk goats selected from a group of fattening male kids were used to determine the indexes of-meat performances and qualities systematically. Also, multiple statistics was used to analyse the interrelations among the indexes in details. The results showed that there was a significant difference in the slaughter and carcass traits of kids with different body weights. Cholesterol content in goat meat was much lower than that in other animal meat. The difference of fatty acid composition between muscle and adipose tissue was very significant. The coefficient of live weight and carcase weight reached as high as 0.97. The typical relative coefficient of two traits also reached 0.96. The LDH and CPK activity of muscle tissue was determined for the first, thus, providing some information for the further research about meat texture properties.
