摘要: 目的:研究日粮中添加N-氨甲酰-L-谷氨酸(NCG)及精氨酸(Arg)对断奶小鼠生长性能的影响。方法:首先通过在日粮中添加0.025%、0.05%、0.1%的NCG,研究NCG对断奶小鼠生长性能的影响。在此基础上,选择同时添加0.05%的NCG和3个水平(0.025%、0.05%、0.1%)的Arg,研究NCG与Arg联合作用对断奶小鼠生长性能的影响。结果:日粮中添加0.1%的NCG,断奶小鼠平均日增质量较对照组提高了12.40%,饲料与体质量比与对照组相比下降了14.65% ;同时添加0.05%的NCG和0.025%的Arg,断奶小鼠平均日增质量提高了10.53%。结论:日粮中添加0.1%的NCG能显著提高断奶小鼠生长性能;日粮中同时添加0.05%的NCG和0.025%的Arg,断奶小鼠生长性能也得到显著提高,其提高生长性能的效果与添加0.1%剂量的NCG达到相同水平。

Abstract: Objective: To investigate the positive effect of N-carbamyl-L-glutamic acid (NCG) and arginine in diet on the growth performance of weaning mice. Methods: First, 0.025%, 0.05% and 0.1% NCG was added in the diet of weaning mice to explore the effect of NCG on the growth performance of weaning mice. Moreover, the diet containing 0.05% NCG combined with arginine at the concentrations of 0.025%, 0.05% and 0.1% was also used to explore the growth performance of weaning mice. Results: The addition of 0.1% NCG in the diet of weaning mice could increased the average daily weight gain by 12.40% and reduce the feed/gain ratio by 14.65% when compared with the control group. Simultaneous additions of 0.05% NCG and 0.025% arginine could result in a 10.53% increase of average daily weight gain when compared with the control group. Conclusion: The addition of 0.1% NCG in diet can significantly improve the growth performance of weaning mice. Simultaneous additions of 0.05% NCG and 0.025% arginine can also significantly improve the growth performance of weaning mice, with the same efficiency as that of 0.1% NCG alone.
