摘要
在养猪生产中,随着窝产仔数提高,仔猪初生重和均匀度降低,从而影响仔猪后期的生长发育。目前对仔猪初生重和均匀度调控的主要方式是营养调控,本文综述了仔猪初生重和均匀度的影响因素及调控机理,特别关注了氨基酸、蛋白质和能量等在调控仔猪初生重和均匀度的作用效果及其相关机理,以期为提高猪生产效率提供依据。
In pig industry,with the increase of litter size,the birth weight and within-litter variation of piglet decrease,consequently influence on the growth and development of piglets after birth.At present,the main way to regulate the birth weight and within-litter variation of piglets is nutrients.This paper reviews the effects of nutrients,especially amino acids,protein and energy,on birth weight and within-litter variation and their mechanism in piglets,in order to provide a basis to improve pig productive efficiency.
