摘  要：
试验就高、中、低3个不同能量水平(7.21MJ/天;10.33 MJ/天;13.49 MJ/天)对36只4~5月龄杂交母羔的羊肉系水力、pH和剪切力的影响进行了研究。结果表明:中能量组和低能量组相比,羊肉系水力、pH和剪切力差异均不显著(P>0.05)。高能量组羊肉系水力、pH显著高于低能量组(P<0.05);高能量组背最长肌剪切力显著低于中、低能量组(P<0.01);高能量组股二头肌剪切力显著低于低能量组(P<0.01)。说明日粮能量水平对羊肉品质有影响。

摘  要：
Thirty six female lambs were selected to study the effects of energy level on water holding capacity,pH values and shear force in the experiment.The lambs were randomly divided into 3 groups and the energy levels were 7.21MJ/d(low energy group),10.33 MJ/d(middle energy group) and 13.49 MJ/d(high energy group) respectively.The results showed that there were no obvious difference on water holding capacity,pH value and shear force between the middle energy group and the low energy group(P>0.05).The water holding capacity and pH value of high energy group were significantly higher than those of low energy group(P <0.05).The longissimus muscle shear force of high energy group was significantly lower than those of middle energy group and low energy group(P<0.01).The biceps femoris shear force of high energy group was significantly lower than that of low energy group(P<0.01).In conclusion,dietary energy level had influence on mutton quality.
