摘要
以天祝藏羊和甘肃高山细毛羊为试验对象,探讨高寒牧区羔羊的最优育肥模式。采用全舍饲方式进行羔羊短期育肥试验,观测其育肥期总增重、平均日增重,并分析育肥经济效益。结果表明:试验组藏羊与细毛羊的日增重都显著高于对照(P<0.05);细毛羊增重显著高于藏羊(P<0.05)。藏羊在饲喂量为0.25kg/d时,增重效果最优,经济收益达到38.7元/只;细毛羊在饲喂量为0.3kg/d时,增重效果最佳,经济收益达到180.6元/只。说明以甘肃高山细毛羊为育肥品种,以0.3kg/d的饲喂量是高寒牧区最优的育肥模式。
The lambs of Tibetan sheep (TS)and Gansu alpine fine wool sheep (AFWS)were selected to study the short-tern fattening pattern in alpine pastoral region in eastern Qilian Mountains .The bodyweight&amp;nbsp;gain,daily bodyweight gain and cost were recorded.The results showed that there was significant different in the daily bodyweight gain between breeds (P &lt;0.05).The daily bodyweight gain of TS and AFWS were higher than the control.The daily bodyweight gain of AFWS were significant higher than TS (P &lt;0.05 ).The daily body weight gain and economical benefit of TS were 0.25 kg/day and 38.7 RMB Yuan/lamb,which were the best among treatments.And they were 0.3 kg/day and 180.6 RMB Yuan/lamb for AFWS,which were the best among 3 treatments.It could be concluded that AFWS was the optimal breed for short-tern fattening and the op-timum supplement amount was 0.3 kg/day.
