| 摘 要： | 核苷酸已逐渐被看做是一种条件营养素。对于处于快速生长期的肉仔鸡、肉鸭、断奶仔猪等幼龄动物,应该保证饲料中含有足够的核苷酸。本文分别从饲料业重点关注的提高日增重,缩短饲养周期;增强消化功能,降低饲料能量蛋白需求;减少腹脂沉积,提高屠体价值;提高健康程度,降低死淘率;以及增强甜菜碱对蛋氨酸的替代作用等五项生产性能指标出发,初步综述和探讨了补充外源核苷酸的使用效果和对应的作用机理。旨在对增强饲料科学研究人员和从业者对核苷酸添加剂的认识,起到抛砖引玉的作用。

| Abstract: | Nueleotide has been regarded as a conditional essential nutrient. For the hruiler chickens, ducks, and weaning piglets, young animals in the period of rapid growth should ensure sufficient nucleotides in feed. Effeets of nueleotide additive on production performance indexes are foeus on in feed industry. The five effects are to improve the daily weight gain and shorten the feeding period, to enhance the digestive function and lrduee feed energy and protein requirements, to reduee the abdominal fat deposition and improve the carcass value, to improve the health level and reduce mortality, and to enhance the substitulion effeet of hetaine on methionine. The using effect and corresponding ,nechanisms of added exogenous nucleotides are preliminary reviewed, in order to enhance the understanding of the feed science researchers and practitioners on nueleotide additive. |
