摘要
对6月龄的陶寒F2代羔羊(DHF2)、特陶寒F2代羔羊(THF2)的体重及体尺指标进行了测定和分析.结果表明,平均初生重陶寒F2羔羊为4.124 6 kg、特陶寒F2为3.737 5 kg.6月龄时特陶寒F2代与陶寒F2代羔羊的平均体重分别为29.91 kg和32.39 kg.陶寒F2代与特陶寒F2代羔羊的公母羔在体长、体高、管围、胸围、胸宽、胸深之间均差异显著(0.01<P<0.05).两品种羔羊的体重均与胸围有着极显著的相关性(P<0.01).
The body weight and body measurements of hybrid lambs of at 6 month old,Dorset×（Dorset×Small-tail Han）（DHF2） and Texel×（Dorset×Small-tail Han）（THF2）,were compared and analyzed.The results showed that the average birth weight of DHF2 was 4.124 6 kg,and that of THF2 was 3.737 5 kg.At 6 months old,the body weights were separately 29.91 kg and 32.39 kg.The body length,body height,vessel length,chest length,chest depth and chest width of DHF2 were significantly superior to the THF2.The body weight of both of hybrid lambs was significantly correlated to their chest（P〈0.01）.
