苏氨酸在养猪生产中的应用研究

Study on the application of Threonine in the pig breeding

苏氨酸是猪营养需要的必需氨基酸,尤其是添加合成赖氨酸配制低蛋白日粮时,猪日粮中的苏氨酸就成为第一限制性氨基酸,可进一步改善饲料的氨基酸平衡和降低饲料的配方成本。本文综述了苏氨酸在养猪生产中的生理作用、免疫功能、缺乏症、营养需要量和应用效果。

Threonine is one of the essential amino acids for breeding pigs,especially when the diets are formulated with low protein by adding L-lysine. Threonine in pig's diet will be the first restricted amino acid,it can improve the amino acid balance in feed and reduce the feed cost. The physiological functions,immunity,deficiency disease,nutrition requirement and effect of Threonine were summarised in this article.
