核苷酸在动物生产中的应用

核苷酸具有许多重要的生理生化功能，外源性核苷酸对机体的免疫功能、肠粘膜的分化和修复、蛋白质的合成、脂类代谢等产生重大的影响，通过在早期断奶仔猪日粮中添加2—5％替代血将蛋白粉的试验证明，试验组和对照组的生产末重并没有显著差异，添加核苷酸组死亡率明显降低。核苷酸完全可以替代血将蛋白粉。在肉用仔鸡日粮中添加0．6％的核苷酸，可以提高肉鸡的日增重、提高饲料转化率，同时还可以改善鸡肉的着色，减少死淘率。

Nucleotides have a variety of physiological and biochemical function Dietary Nucleotides have an important effect on immune system, recovery ofl ntestinal mucous, protein metabolism,lipid metabolism. the addition of Nucleotides （2 -5% ） on weaning piglet feeds in replacement of blood plasma As far as final weight gain there was no differences between threatments, however, the threatment with Nucleotides a- chieved a much lower mortality rate. The present data suggests that Nucleotides can replace blood plasma in piglet diets, the addition of Nucleotides（0.6% ） on broiler feeds, Nucleotides can improve the daily weight gain, final weight gain and feed conversion, it also noticed an improvement pigmentation of chicks, which also corrobrate the general improvement on health status of broilers and have a much lower mortality rate.
