摘要:

本试验就高、中、低3个不同能量水平(7.21MJ/d;10.33 MJ/d;13.49 MJ/d)对36只4-5月龄杂交母羔的羊肉系水力、pH值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值和剪切力差异均不显著(P>0.05)。高能量组羊肉系水力、pH值显著高于低能量组(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。

Abstract:

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.
