Factors Affecting Digestion and Scientific Feeding Measurements of lactating Calves
The physiological characteristics of calves are complex,and their digestive system is not fully devel-oped,especially the functions of rumen,reticulum and valvular stomach are weak in the neonatal stage,mainly rel-ying on abomasum for digestion.The immune system has not been fully established,and the resistance to the exter-nal environment is weak.As the main source of nutrition in the early stage of calves,the quality and quantity of liquid feed have an important effect on the growth and health of calves among the factors affecting calf digestion.The composition and physical morphology of solid feed also significantly affect the digestion process of calves,and reasonable intake of solid feed is helpful to promote the development and function of the rumen in calves.This pa-per explores the digestive physiological characteristics of calves and its influencing factors,and put forward scientif-ic feeding strategies from two aspects of liquid feed and solid feed,in order to provide reference and guidance for scientific feeding of calves at the stage.
