| 摘 要： | 试验旨在比较N-氨甲酰谷氨酸（NCG）和瘤胃保护型NCG（RP-NCG）对滩羊生长性能、血清生化指标和脂肪分配的影响。选取日龄相近、体重为（20.14±0.31）kg公滩羔羊60只，随机分为3组：对照组、0.1% NCG处理组和0.1% RP-NCG处理组，每组5个重复，每个重复4只羔羊。对照组不添加NCG，0.1% NCG组添加0.1% NCG，0.1% RP-NCG组添加0.1% RP-NCG。试验期80 d。结果显示：①与对照组相比，日粮中添加NCG和RP-NCG能够显著提高滩羊平均日增重并降低料重比（P<0.05），但两试验组之间差异不显著（P>0.05）；②日粮中添加NCG和RP-NCG，显著降低了血清尿素氮含量（P<0.05），但对血清总蛋白、肌酐和肌酸激酶的活性影响不显著（P>0.05）；③与对照组相比，添加NCG和RP-NCG使滩羊净肉重/胴体重显著提高（P<0.05），皮下脂肪和GR值显著下降（P<0.05），两试验组间差异不显著（P>0.05）；试验组肌内脂肪（IMF）含量显著升高（P<0.05）。综上所述，日粮添加0.1% NCG或0.1% RP-NCG可提高舍饲滩羊生长性能，并能改善滩羊脂肪分配。与RP-NCG相比，NCG对滩羊生长性能、血清生化指标及脂肪分配无显著影响。 |

| Abstract: | The objective of the present experiment was to determine the effect of different types of N-carbamoylglutamate on growth performance,serum biochemical indexes and fat distribution of Tan sheep. Sixty male Tan lambs with average weight of (20.14±0.31)kg and similar age were randomly assigned three groups with five replications per group and 4 lambs per replication. The lambs in control group were fed basal diet, while lambs in test groups were fed diets containing 0.1% NCG and 0.1% RP-NCG,respectively. The results showed that:① Comparing with control group,the ADG was significantly improved (P<0.05) and F/G was significantly decreased (P<0.05) when 0.1% NCG or 0.1% RP-NCG were supplemented,while there was no significant difference between two experimental groups (P>0.05).② Dietary supplemented with 0.1% NCG or 0.1% RP-NCG significantly decreased the serum urea nitrogen (P<0.05),but there were no significant differences in serum total protein,creatinine content and creatine kinase activity (P>0.05).③ The ration of meat weight to carcass weight of two experimental groups was significantly improved (P<0.05).As 0.1% NCG or 0.1% RP-NCG were supplemented in the diets, the content of subcutaneous fat and GR value were significantly decreased (P<0.05),and the content of intramuscular fat (IMF) was significantly increased (P<0.05).In conclusion,dietary supplemented with 0.1% NCG or 0.1% RP-NCG could improve the growth performance and slaughter performance while there was no significant difference between NCG and RP-NCG. |
