Description

An infographic describing the effects of heat stress on the estrous behaviour of female dairy cows and ways to minimize them. This infographic includes general effects of heat stress, what normal estrous behaviour looks like, what estrous behaviour looks like while experiencing heat stress, and various methods that can be used by farmers to prevent heat stress and increase reproductive success.
