不同品种断奶羔羊早期育肥效果研究

Study on the fattening effects of weaned lambs of different varietie

选用3月龄的萨福克羊、杜泊羊的断奶后羔羊共30只,根据品种分为两组,每组15只,分别圈养在2个圈中,并在相同的营养条件下饲喂60 d,对比其断奶后生长发育情况.结果表明,在相同的饲养管理条件下,萨福克羊日增质量可达(292.22±18.20)g,料重比为3.26:1,而杜泊羊的日增质量为(201.11±20.38)g,料重比为3.48:1.说明相同饲养管理条件下,萨福克羊的饲料转化率和生产性能明显高于杜泊羊.

30 weaned lambs of suffolk and dorper sheep, which were three month old were chosed in this study. They weredivided into two groups based on the different varieties. They were kept in two pens and fed 60 d under the same feedingand management condition. Then compared the growing development of those weaned lamps and found that the result was dif-ferent. The daily gain of suffolk was （292.22±18.20） g, and the feed conversion rate was 3.26：1. However, the daily gain ofdower sheep was （201.11±20.38） g, and the feed conversion rate was 3.48：1, which meaned that the FCR of suffolk andwhose growth performence was evidently higher than the dower sheep under the similar feeding and management condition.
