Abstract

The combined effects of high ambient air temperature, relative humidity, and solar radiation have profound effects on milk yield, growth, reproduction, and cow health. In the lactating cow, total body heat load is significantly escalated by an increase in metabolically-derived heat associated with milk production. Whenever heat gain is greater than heat loss body temperature rises, heat stress results and performance is proportionally reduced.
