摘要
本试验以萨福克羊为父本、哈萨克羊为母本,验证在放牧条件下,萨哈杂交一代的育肥和产肉性能。经过对萨哈杂交一代的测定,在放牧条件下,0~8月龄萨哈F1日增重提高24 g,比哈萨克羊提高了14.9%;体重比哈萨克羊提高5.95 kg,比哈萨克羊提高了13.9%,差异显著（P〈0.05）;屠宰时萨哈杂交一代比哈萨克羊,宰前活重增加8.32 kg,胴体重增加5.29 kg,净肉重增加4.54 kg,增重效果显著（P〈0.05）,具有父本的明显特征,同时又保持了母本哈萨克羊适应全年放牧的饲养方式。初步认为,萨福克公羊是放牧条件下进行肉羊养殖的合适父本。
This paper aims to compare SK F1 and Kazakstan sheep grazing in the same feeding conditions,the differences of body weight,growth rate,slaughter weight,carcass weight,net meat weight,bone weight,bone weight,net meat rate etc.. A select group of mixed grazing was born in April 2014,the birth weight close to SK F1 and Kazakstan sheep,30 sheep,4 months of lactation. The determination of 4,6,August at the age of the weight and the speed of growth,one full year after slaughter,determination of the weight,slaughter weight,carcass weight,net meat weight,bone weight,bone weight,net meat rate. After the test,compared to the difference between Kazak sheep,SK F1 in body weight,growth rate,slaughter weight,carcass weight,net meat weight has significant effect on weight gain significantly（P〈0.05）. Preliminary think,Suffolk rams suitable for male Kazak sheep improved grazing conditions.
