摘要
以引进的波德代羊与湖羊杂交组合后代(杂交一代、杂交二代)及湖羊为研究对象,旨在为湖羊品种的杂交改良提供理论依据。结果表明:波湖F2羔羊的3月龄、6月龄及周岁体重、体高、体长均极显著高于湖羊(P<0.01),优于波湖F1(P<0.05)。说明利用波德代羊杂交改良湖羊,可以显著提高羔羊的生长发育性能,杂种优势显著。
In order to explore the cross effects of Borderdale with Hu sheep,the growth traits of Hu sheep and its hybrids were compared. The results showed that the weight, height,length of F2 lambs at 3-month-old,6-month-old and 12-month-old were very significantly higher than those of Hu sheep（P〈0.01 ） and significantly higher than those of FI（P〈0.05 ）.It indicated that the hetercsis between the two sheeps was obvious.
