Abstract

Dietary physically effective neutral detergent fiber (peNDF) is critical in maintaining rumen function, decreasing the risk of metabolic disorders and preventing the decrease of performance of dairy cows. Rumen degradable starch (RDS) content is related to the type and processing method of grain, as well as the passage rate of digesta from the reticulo-rumen. In order to provide a theoretical guidance for production, balance between dietary peNDF and RDS and its effects on rumen fluid pH and performance of dairy cows are reviewed in this paper.

Key words： physically effective neutral detergent fiber; rumen degradable starch; rumen pH; performance
