| 摘要: |
| 应用“CNT”及“9211”增重剂处理枯草期同羊。结果表明,两种增重剂可有效促进同羊生长,防止掉膘损失,增重效果达50%以上;在改善同羊胴体组成方面,“9211”增重剂可使眼肌面积、后腿重和熟肉率分别提高8. 89%, 21. 19%和2. 00%,“CNT”增重效果则相应为11. 83%, 10. 24%和7. 81%. |

| Abstract: |
| Two kinds of weight grow agents of Cyclic Nucleotides (CNT) and "9211" were used in this research in order to study the effects of these on castrated Tong Sheep growth in grass-withering period.The results showed that two kinds of weightgrow agents could significantly improve the growth of Tong Sheep with the weight-grow efficiency by over 50%;and in the carcass composition improvement, eye muscle area,hind-limb weight and rate of ripening meat could be increased by 8.89%,21.19% and 2.00% respectively with "9211"; and increased by 11.83%, 10.24% and 7.81% respectively with CNT. |
