摘　　要：本研究对川北地区繁育推广的天府肉羊与本地山羊杂交改良羊(天改羊)的生长性能进行抽样测定,结果表明:用天府肉羊改良本地山羊具有明显的杂交优势,改良羊(天改羊)的生产性能显著高于本地山羊。与本地山羊相比,2月龄天改公羊体重提高了33.13%,母羊体重提高了51.25%;9月龄天改公羊体重提高了47.31%,母羊体重提高了59.18%;体尺方面,9月龄天改公羊的体高、体长和胸围分别比本地山羊提高了17.35%、18.24%和8.14%,天改母羊分别提高了22.76%、18.96%、14.30%。The production performances of hybrid goats improved from local goat crossbreeding with Tianfu meat goat in North Sichuan were tested in this text.The results showed that the performances of improved goats were significantly higher than that of the local goats.Compared with the local goats,the body weight of improved bucks increased by 33.13% at two months,and the body weight of improved ewes increased by 51.25%.The body weight of improved bucks increased by 47.31%,and improved ewes increased by 59.18% at nine months.As for body sizes,the body height,body length and chest circumference of the improved bucks increased by 17.35%,18.24% and 8.14%,compared to the local bucks at nine months,and the body sizes of the improved ewes increased by 22.76%,18.96% and 14.30% respectively.
