肉羊饲粮碳水化合物营养研究进展OA
Advances in Dietary Carbohydrate Nutrition in Meat Sheep
饲粮中碳水化合物的构成对肉羊的生产性能有着重要影响.目前,饲粮精粗比和非纤维性碳水化合物与中性洗涤纤维的比值(NFC/NDF)是反映饲粮碳水化合物构成的常见指标.饲粮中适宜的碳水化合物构成不仅可以提高肉羊生产性能,还可以调节瘤胃发酵过程,维持瘤胃微生态环境稳定,预防营养代谢病的发生.本文通过综述饲粮不同碳水化合物构成对肉羊瘤胃微生态、生产性能以及机体代谢和健康影响的研究进展,以期为肉羊生产中饲粮碳水化合物的应用提供参考.
The dietary carbohydrate composition plays a crucial role in the performance of meat sheep.At pres-ent,the dietary concentrate to forage ratio and the ratio of non-fiber carbohydrates to neutral detergent fiber(NFC/NDF)are common indicators reflecting the carbohydrate composition in diets.An appropriate dietary carbohydrate composition can not only improve the performance of meat sheep,but also regulate the rumen fer-mentation process,maintain the stability of the rumen microecological environment,and prevent the occurrence of nutritional metabolic diseases.This article reviewed the research progress on the effects of different dietary carbohydrate composition on the rumen microecology,performance,metabolism and health of meat sheep,with the aim of providing a reference for the application of dietary carbohydrates in meat sheep production.[Chinese Journal of Animal Nutrition,2026,38(5):3244-3256]
