| 摘 要： | 以萨福克羊、陶赛特羊为父本与小尾寒羊进行杂交,在同等饲养管理条件下,其萨寒F1、陶寒F1与小尾寒羊间在90 d育肥期内日增重差异极显著(P0.01);6月龄胴体重差异显著(P0.05),6月龄屠宰率差异显著(P0.05),萨寒F1与陶寒F1间差异都不显著(P0.05)。实验表明:萨寒F1、陶寒F1生长速度快、产肉性能高的优点已在其杂交后代身上体现出来,杂种优势显著。

| Abstract: | Crossbred lambs of Suffolk （♂ ） x Small Tail Hah Sheep（ ♀ ） and Dorset Sheep（ ♂ ） x Small Tail Han Sheep （ ♀ ） , with the same conditions of breeding and management, there was signiticant different aa daily weight gain during fatting of 90 days, carcass weight and slaughter percentage of 6-month-old among Suffolk-Han F1, Dorset-Han F1 and Han sheep （P 〈0.01 ）. No difference was observed on growth performance between Suffolk-Han F1 and Dorset-Han F1 （ P 〉 0. 05 ）. The experiment indicated that the advantages of faster growing and higher meat production of Suffolk-Han F1 , Dorset-Han F1 have represented in crossbred offspring, in addition, heterosis was apparent. |
