摘  要:
选择 4~ 5月龄体重相近的杂种羔羊 90只 ,随机分成对照、添加半胱胺 (CS87)和生长抑素 (SS)苗免疫共 3组 ,每组公母各半。CS87按每千克体重 80mg每周添加 1次 ,持续 6周 ;SS苗按 1mL/只一次性免疫 ,9周结束。结果显示 ,添加CS87组 0~ 2 1d增重提高 1 6 46 % (P <0 0 5) ,2 1~ 42d增重提高 1 5 95 % (P <0 0 5) ;SS苗免疫组在 2 1~ 42d提高 5 86 % (P >0 0 5) ,42~ 63d提高 1 7 5 % (P <0 0 5) ,母羊效果优于公羊。

摘  要:
Ninety 4~5 month old crossbred lambs were divided into 3 groups based on their weight and sex to examine the effects of CS 87 and SS vaccine on growth.Thirty lambs were orally administrated with CS 87 (80 mg/kg BW)once a week for 42 d and thirty lambs were immunized with SS vaccine(1 mL/lamb)just one time during 63 d.Results showed that CS 87 increased weight gain by 16 46%(P<0 05)from 0~21 d and 15 95%(P<0 05) from 21~42 d.SS vaccine sligtly increased weight gain by 5 86%(P>0 05) from 21~42 d and significantly increased weight gain by 17 56%(P<0 05)from 42~63 d.The result also indicated that female lambs got more benefit from SS vaccine than the male lambs did.
