摘要
为探究槟榔江公水牛和德宏公水牛的肉品质及开发利用其肉用价值,分别选取(33±3)月龄的槟榔江公水牛(BLJ组)和德宏公水牛(DH组)各10头,在相同饲养管理条件下,每头补饲精料3 kg/d,自由采食全株玉米青贮,预实验期10 d,正式实验期90 d。结果表明:BLJ组的背最长肌和股二头肌肉色亮度值、红度值、黄度值均明显高于DH组,眼肌面积极显著高于DH组(P<0.01)。在饱和脂肪酸中,BLJ组背最长肌C17:0、C18:0相对含量极显著高于DH组(P<0.01),C16:0相对含量显著低于DH组(P<0.05);BLJ组股二头肌中C18:0相对含量极显著高于DH组(P<0.01),C17:0显著高于DH组(P<0.05);多不饱和脂肪酸中,BLJ组股二头肌和背最长肌中C22:4 n-6相对含量极显著高于DH组(P<0.01),背最长肌中C20:4 n-6和C22:5 n-6相对含量显著高于DH组(P<0.05)。BLJ组背最长肌中易引发高胆固醇血症的多不饱和脂肪酸相对含量显著低于DH组(P<0.05);BLJ组的股二头肌胆固醇含量显著高于背最长肌(P<0.05),其背最长肌胆固醇含量极显著低于DH组(P<0.01)。综上,槟榔江水牛眼肌面积更大,肉色鲜红明亮,2种牛肉胆固醇含量较低,肌肉脂肪酸组成合理,均为优质脂肪酸肉类。
In order to investigate the meat quality of Binglangjiang and Dehong buffalo bulls and to exploit their meat value,Binglangjiang(BLJ)and Dehong(DH)buffalo bulls at(33±3)months of age(n=10 for each breed)were fed a concentrate feed at 3 kg/d per animal and ad libitum whole-plant maize silage under the same conditions of feeding and management.The pre-experimental period lasted 10 d and the experimental period lasted 90 d.The results showed that the color parameters brightness,redness,and yellowness values of the longissimus dorsi and biceps femoris muscles in the BLJ group were significantly higher than those of the DH group(P<0.05),and the eye muscle area was highly significantly higher than that of the DH group(P<0.01).Of the saturated fatty acids(SFA),C17:0 and C18:0 significantly increased(P<0.01)while C16:0 significantly decreased(P<0.05)in the longissimus dorsi muscle of the BLJ group when compared to the DH group;in the biceps femoris muscle of the BLJ group,the relative content of C18:0 was significantly higher than that of the DH group(P<0.01),and the relative content of C17.0 was significantly higher than that of the DH group(P<0.05).Among the polyunsaturated fatty acids(PUFA),the relative content of C22:4 n-6 in both muscles was significantly higher in the BLJ group than in the DH group(P<0.01),and the contents of C20:4 n-6 and C22:5 n-6 in the longissimus dorsi muscle of the BLJ group were significantly higher than those of the DH group(P<0.05).The relative content of PUFAs associated with hypercholesterolemia in the longissimus dorsi muscle significantly decreased in the BLJ group relative to the DH group(P<0.05).For the BLJ group,the content of cholesterol was significantly higher in biceps femoris than in longissimus dorsi (P < 0.05), and the content of cholesterol in longissimus dorsi was highly significantly lower than that of the DH group (P < 0.01).In conclusion, the longissimus dorsi of Binglangjiang buffalo bulls had larger eye muscle area and a bright red color. Both beefmeats were low in ch
