摘要
Abstract
The Hu sheep and Small-tailed Han sheep were treated for estrus synchronization and cross experiment mated by Dorper,Poll Dorset and Black Suffolk Rams in unoestrus season to explore the production technologies of fat lamb in the farming-pastoral region of Northern Shaanxi.The results showed that average birth weights of F1 lambs from DH(Dorper ♂ × Husheep ♀),DS(Dorper ♂ × Small-tailed Han sheep♀),PH(Poll Dorset ♂ × Husheep ♀)and PS(Poll Dorset ♂ × Small-tailed Han sheep♀)were similar,but the differences of growth rates at late were significant,the DH F1 Lambs grew fastest before 4 months old.Their growth rates were faster than that of Hu sheep and Small-tailed Han sheep,and the order was DH＞ DS＞ PH＞ PS.The same phenomenon was also observed in three-way cross lambs.Their average body weight at 2 months old reached more than 22 kg,and the body weight at different ages were significantly higher than that of two-way cross lambs.therefore Suffolk is the ideal terminal sire breed and threeway cross lambs were more suitable for the production of fat lamb.关键词
