Research progress on demand and dietary supply levels of protein in pigs at different growth stages
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.
