【摘要】：为了研究蒙古羊与杜泊羊的杂交优势,试验测定了以蒙古羊为母本、杜泊羊为父本的杜蒙F1代羔羊屠宰性能及肉品质。结果表明:杜蒙F1代羔羊前胸宽深,后躯丰满,肉用体型表现优于蒙古羊羔羊;杜蒙F1代羔羊屠宰性能各项指标好于蒙古羊羔羊,其中胴体重、净肉重、净肉率、屠宰率显著高于蒙古羊羔羊(P0.05);杜蒙F1代羔羊肉色鲜红,亮度(L*值)、红度(a*值)大于蒙古羊羔羊,而黄度(b*值)小于蒙古羊羔羊;杜蒙羊F1代羔羊股二头肌、臂三头肌、背最长肌嫩度也优于蒙古羊羔羊相应部位;股二头肌、臂三头肌肌内脂肪含量高于蒙古羊羔羊。说明以蒙古羊为母本、杜泊羊为父本的杂交组合可提高肉羊屠宰性能,改善羊肉色泽及嫩度。
[Abstract]:In order to study the crossbreeding advantage between Mongolian sheep and Dupo sheep, the slaughter performance and meat quality of Dumont F1 lambs with Mongolian sheep as female parent and Dupo sheep as male parent were determined. The results showed that the F _ 1 lambs of Dumont had better slaughter performance than Mongolian lambs, including carcass weight, net meat weight, net meat weight and net meat percentage. The slaughtering rate was significantly higher than that of Mongolian lamb (P0.05A), the meat color of Dumont F1 lambs was bright red, the brightness of lambs was higher than that of Mongolian lambs, and the value of yellowness was lower than that of Mongolian lambs, while that of Dumont F 1 lambs was lower than that of Mongolian lambs, and that of Dumont F1 lambs was lower than that of Mongolian lambs. The tenderness of longissimus dorsi muscle was also superior to that of Mongolian lamb, and the fat content of biceps femoris muscle and triceps arm muscle was higher than that of Mongolian lamb. The results showed that the crossbred combination of Mongolian sheep as female parent and du Bo sheep as male parent could improve the slaughtering performance of meat sheep and improve the color and tenderness of mutton.
