Effect of gender on meat qualities of biceps femoris of Bamei lamb

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.
