摘要 本文对奶牛中性洗涤纤维(NDF)和物理有效中性洗涤纤维(peNDF)营养调控进行了较全面的综述。日粮中NDF能够通过影响奶牛采食、咀嚼和反刍,调节瘤胃中有机酸、pH和微生物的数量等途径对瘤胃发酵进行调控;peNDF的营养调控作用也主要体现在奶牛的采食和消化过程中。日粮中适宜浓度的NDF和peNDF是维持奶牛健康和生产性能的重要因素。 Recent studies on nutritional regulation of neutral-detergent fiber(NDF) and physically effective neutral-detergent fiber(peNDF) on dairy cow are reviewed in the paper.The regulation of NDF on rumen fermentation of cow is by means of effect on food intake,chew and rumination and regulating organic acid,pH and microbial biomass;the regulation of peNDF is on the base of effect on food intake and digestion.Benefiting contents of both NDF and peNDF are key factors to maintain health and production performance of cow.
