Research Progress on Digestive Kinetics Characteristics of Macronutrients in Monogastric Animals
At present,the precision feeding technology represented by the digital model has gradually become one of the mainstream technologies in animal husbandry.The digestive kinetics characteristics of diet and raw materials can reflect the potential of feed nutrition value multidimensional and quantitatively to a certain extent,and can be used to reveal the relationship between the nutrient composition of feed and the endogenous rational changes of animal digestive tract during digestion,and provide dynamic parameters for the establishment of precise feeding models.The purpose of this paper is to analyze the factors affecting the digestive characteristics and digestive kinetics of macronutrients.By reviewing the research progress of macronutrient enzymatic reaction kinetics,chyme transport kinetics,chyme fermentation kinetics and digestible nutrient absorption kinetics,the focus of current research on digestive kinetics of monogastric animals and the problems to be solved are ex-pounded.The application prospect of this method in the research of precision feeding of single stomach animals in the future was prospected,in order to provide reference for the realization of precision nutrition regulation and production performance prediction in the field of single stomach animal production.[Chinese Journal of Animal Nutrition,2024,36(7):4094-4102]
