Blue light from light-emitting diodes (LEDs) directed at a single eye elicits a dose-dependentsuppression of melatonin and affects milk production in dairy cows

摘要

Wearable head masks that direct blue light at a single eye can suppress melatonin (MT) secretion in dairycows. In pasture-based spring-calving multiparous dairy cows, this suppression in melatonin increases milk productionduring early lactation.
