不同生长阶段猪的蛋白质需求及饲粮供给水平效应研究进展

Research progress on demand and dietary supply levels of proteinin pigs at different growth stages

不同生长阶段的猪均具有其独特的生理特点,因此,对饲粮蛋白质的需求也各不相同。而饲粮蛋白质水平的高低不仅影响猪的健康和生长,还与其饲料成本和利用率密切相关,在很大程度上决定着养猪场的经济效益。因此,本文从生产实际出发,在阐述不同生长阶段猪生理特点和蛋白质需求基础上,主要对近年来国内外有关各阶段猪饲粮蛋白质供给水平的研究和应用效果进行了综述,并在最后针对不同阶段猪给出较适宜的饲粮蛋白质配制建议,供养猪生产参考。

Pigs at different growth stages have unique physiological characteristics,therefore their demand for dietary protein varies.The level of dietary protein not only affects the health and growth of pigs,but also is closely related to the feed cost and utilization rate,which largely determines the economic benefits of pig farms.Therefore,starting from the actual production,this paper mainly reviewed the research and application effects of feed protein supply levels for pigs at different growth stages both domestically and internationally,based on elaborating the physiological characteristics and protein requirements of pigs at different growth stages.Finally,suitable feed protein formulation suggestions are provided for pigs at different stages,providing reference for pig production.
