Spray Cooling Effects - Brochure

Hot summer weather can be rough on cows. If temperatures over 80 F persist for long periods of time, death can occur. At the very least, temperatures over 75 F will decrease the feed efficiency and weight gain of cows. Milking cows are of particular concern in such heat because heat stress can reduce their milk production, lower birth weight, and reduce the growth of young cows. Extreme heat stress can cause reproduction problems, and even death.
