Modeling diurnal rumen metabolism dynamics in dairy cattle: An update to a mechanistic model representing eating behavior, rumen content, rumination, and acid-base balance

Discover how eating patterns drive the rumen’s daily rhythm.
This updated mechanistic model reveals how meal frequency and diet type drive fluctuations in rumen volume, acidity, and microbial activity. By integrating diurnal dynamics—rumination, particle breakdown, pH, and lactic acid metabolism—it offers a sharper, more realistic view of rumen function and its responses to different feeding behaviors.
