Chronophysiology as an evolutionary multiscience has enabled ruminants to better cope with the changing environment from the mother nature towards modernity. With the recent discoveries on timing of feeding orchestrating circadian and postprandial nutrient intake and metabolic rhythms, time has already come to contemplate chronophysiology as a foundation of voluntary feed intake (VFI) regulation in dairy ruminants as workable models for humans.
Chronophysiology has been a key missing interscience in realistic modeling and understanding of VFI regulation in high-producing ruminants. The shortcoming gains increasing thoughts given that accurate and reliable nutrient intake predictions are essential to consistent meeting of nutrient requirements and, thus, to profitable human food production. With the recent chronophysiological discoveries on dairy farm management strategies, time has already come to realize that evolutionary circadian rhythms in grazing, chewing, rumen kinetics, and peripheral substrate assimilation can help develop innovative strategies to improve VFI prediction accuracy and dairy ruminant efficiency and health
