| 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。

| Abstract: | Ninety 4～5-month-old crossbred lambs were divided into 3 groupsbased on their weight and sex to examine the effects of CS87 and SS vaccine on growth.Thirty lambs were orally administrated with CS87(80 m g/kg BW)once a week for 42 d and thirty lambs were immunized with SS vaccine(1 m L/lamb)just one time during 63 d.Results showed that CS87 increased weig ht 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 21～4 2 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 t han the male lambs did. |
