摘要:
选择4、6、8月龄巴美肉羊各20只,按性别分类并与同月龄的小尾寒羊、苏尼特羊对比屠宰后实验指标,分别测定其股二头肌的色泽、嫩度、pH和熟肉率,研究基于性别因素的巴美肉羊肉用品质特性。各实验组4月龄母羊的a*值显著(p<0.05)大于其公羊的a*值,而剪切力值显著(p<0.05)小于同类公羊的剪切力值。而除苏尼特羊外熟肉率显著(p<0.05)大于同类公羊的熟肉率。巴美公羊的剪切力值显著(p<0.05)小于寒羊公羊和苏尼特公羊的剪切力值。6月龄巴美母羊和寒羊母羊股二头肌的a*值显著(p<0.05)大于其公羊的a*值。巴美公羊的剪切力值分别显著(p<0.05)小于寒羊公羊和苏尼特公羊的剪切力值。8月龄巴美母羊和巴美公羊的a*值显著(p<0.05)小于苏尼特母羊和苏尼特公羊的a*值。同时,8月龄巴美母羊和苏尼特母羊的熟肉率显著(p<0.05)大于其对应公羊的熟肉率。各实验组的pH24显示6月龄表现出了优质的肉质特性,且其剪切力值随着月龄增加呈先显著下降后显著上升趋势(p<0.05)。同时,熟肉率随着月龄增加却呈现出先显著增加后显著下降趋势(p<0.05)。实验得出,性别因素对肉品质具有影响,巴美母羊在6月龄时表现出色泽、嫩度以及持水性能的优势。

Abstract:
In this experiment,Bamei lamb at 4 months-of-age,6 months-of-age and 8 months-of-age were chosen to make a slaughter experiment with small tailed sheep and Sunit lamb at same age. According to the comparison of colour,tenderness,p H and cooked rate from biceps femoris of different gender,the result showed that the value of a* was significant higher(p <0.05),whereas the shear force was significant lower(p<0.05) in meat from female than male at 4 months-of-age among these three breed. Meanwhile,the cooked rate of these breed was significant higher(p<0.05) in female than that of male at 4 months-of-age,except the breed of Sunit. The value of a* in female of Bamei and female of small tailed sheep was higher than that of male in Bamei and small tailed sheep at 6 months-of-age,respectively(p<0.05). Moreover,the shear force in male of Bamei was lower than that of small tailed sheep and Sunit lamb,respectively(p<0.05). The female of Bamei and the male of Bamei had lower value of a* than that of Sunit(p<0.05). In addition,the cooked rate in female of Bamei and female of Sunit was higher than that of male at 8 months-of-age(p<0.05). The value of p H24 exhibited an advantage quality of meat at 6 months-of age,and the shear force in these three breed decreased from 4 months-of-age and increased from 6 months-of-age(p<0.05). However,the cooked rated exhibited an opposite tendency(p<0.05). In a conclusion,gender affected meat quality significantly,particularly for 6 months old Bamei who expressed an advantage colour,tenderness and water holding capacity.
