我国地方猪能量需要研究进展

Research Progress on Energy Requirement of Chinese Indigenous Pigs

我国地方猪种质资源丰富,但由于地方猪生长速度缓慢、瘦肉率低,导致地方猪养殖未受到重视。由于缺乏对地方猪营养需要的认识,地方猪日粮设计一定程度上存在不合理的现象,限制了地方猪生长性能的发挥。日粮能量主要用于维持自身和生产的需要,适宜的日粮能量水平能使地方猪的生长性能和胴体性状得到最大发挥。然而,猪能量需要的研究主要集中在国外猪种上,而在我国地方猪上的研究较少。因此,文章综述了我国地方猪近几年能量需要的相关研究,以期为我国地方猪科学研究和精准饲养提供参考。

China has abundant indigenous pig breeds,little attention has paid to these breeds due to their slow growth rate and low lean meat percentage.The lack of nutrient requirement of indigenous pigs leads to the irrational design of dietary formulation,which limits the growth performance of indigenous pigs.Dietary energy is mainly used for meeting the requirement of maintenance and production,with ap⁃propriate energy level in diet can maximize the growth performance and carcass traits of indigenous pigs.However,the studies of energy requirement mainly focus on foreign pig breeds,there are less studies on Chinese indigenous pigs.Therefore,this paper reviews the recently research on energy requirement of Chinese indigenous pigs,so as to provide references for the scientific research and precision feeding of Chinese indigenous pigs.
