摘　　要：反刍动物氮的利用率低,瘤胃内可溶性碳和可溶性氮平衡这一原理有助于解决这一问题。文章总结了可溶性碳和可溶性氮在瘤胃的代谢过程、评价可溶性碳/可溶性氮平衡的指标、可溶性碳/可溶性氮对反刍动物代谢影响以及调控可溶性碳/可溶性氮平衡措施,以期为提高反刍动物氮利用率提供参考依据。As known,ruminants have poor nitrogen efficiency.The balance between soluble carbohy⁃drates and soluble protein may help to improve nitrogen efficiency.This review outlines the metabolic process of soluble carbohydrates and soluble protein in the rumen,indicators to evaluate the balance be⁃tween soluble carbohydrates and soluble protein,the metabolic impact of balance of soluble carbon and soluble nitrogen in ruminants,and measures for regulating the balance of soluble carbon and solub pro⁃tein.
