不同肉羊品种与湖羊杂交F1代羔羊育肥性能研究

Study on Fattening Performance of F1 Lambs from Different Mutton Breeds Crossing Hu Sheep

为研究湖羊杂交F1代生长育肥性能,试验以湖羊为母本,选择不同肉羊为父本(特克赛尔、杜泊、无角陶赛特羊)。在舍饲饲养管理条件下,测定其F1羔羊的初生重、2月龄重、4月龄重和6月龄重,平均日增重等生长性能,并进行经济效益分析。结果表明:试验Ⅰ组(特湖羊)、试验Ⅱ组(杜湖羊)和试验Ⅲ组(陶湖羊)6月龄平均重分别比对照组Ⅳ(湖羊)高出24.43%、32.42%、20.51%,差异极显著(P<0.01)。利润较对照组分别多收入178.34元、251.65元、156.60元,差异极显著(P<0.01)。其中试验Ⅱ组的生长性能和利润均优于试验Ⅰ组和试验Ⅲ组,差异显著(P<0.05)。

In order to study the crossbreeding effect between different mutton breeds(Texel, Dorper and Dorset sheep) and Hu sheep. The growth performance of F1 lambs,including birth weight,the body weight at the age of 2-month,4-month,6-month and average daily gain,were measured under the housed feeding and management. The results showed that the 6-month-old body weight of Texel, Dorper and Dorset F1 were significantly higher than Hu sheep group for 24.43%、32.42%、20.51%,respectively(P<0.01).The profit of experimental groups were higher than Hu sheep group for 178.34、251.65、156.60 yuan(P<0.01), and the growth performance and profit of group Ⅱ was higher than group Ⅰ and group Ⅲ(P<0.05).
