杂交对杜泊羊与蒙古羊杂交后代屠宰性能及肉品质影响
Effect of Cross-breeding on Slaughter Performance and Meat Quality of Hybrid Offspring of Dorper and Mongolian Sheep
摘要
Abstract
In order to assess the heterosis of Dorper and Mongolian Sheep, the Mongolian goat and the first-filial generation (F1) and second-filial generation (F2) of hybrid offspring of Dorper and Mongolian Sheep were selected to statistically evaluate their slaughter performance and meat quality. The results showed that at the age of six months, the F2 offspring had higher live weight, carcass weight, pure meat percentage, slaughtering percentage, carcass products percentage, and eye muscle area than that of F 1 offspring and Mongolian Sheep, and significant differences in live weight, carcass weight, pure meat percentage and slaughtering percentage between F2 offspring and Mongolian Sheep were observed (P<0.05);the sequence of L*value of triceps surae and longissimus dorsi was F2 offspring>F1>Mongolian Sheep;F2 and F1 offspring had higher shear stress and better tenderness than that of Mongolian Sheep. The combined data showed that the slaughter performance was improved by hybrid. The meat of the hybrid offspring achieved better performance in color (bright red colored) and tenderness than that of parents. The heterosis is expressed by cross-breeding of fine sheep breeds.关键词
