反刍动物碳水化合物代谢利用机制及消化道健康的系统营养调控研究进展

Research Advances in System-Nutritional Regulation on Mechanism of Carbohydrates Metabolism and Gastrointestinal Health of Ruminants

碳水化合物是反刍动物体内的主要能量来源,在维持动物生长发育、机体代谢和生产性能等方面发挥关键作用。饲粮中碳水化合物结构是否合理对能量利用效率、动物生产性能和消化道健康有重要影响。本文系统分析和综述了反刍动物饲粮中碳水化合物的利用机制及其对消化道健康的影响的最新研究进展,并提出系统营养调控技术措施,为提高饲粮碳水化合物的利用效率和动物消化道健康营养调控决策提供参考。

Carbohydrate is the main source of energy in ruminants and plays a key role in maintaining growth,metabolism and production performance of animals.The dietary composition which related reasonable carbohydrates supply have important impacts on energy efficiency of animal production performance and the digestive tract health.In this paper,the mechanism of dietary carbohydrate utilization and its influence on digestive tract health in ruminants were systematically analyzed and summarized,and the technical measures of systematic nutrition regulation were put forward to provide references for improving the utilization efficiency of dietary carbohydrate and regulating gut healthy nutrition in animals.
