Preparing cows for heat stress with proper nutrition and feeding practices can improve their body’s response and may help your herd be more successful this summer.
Heat stress occurs when an animal generates and absorbs more heat than it can dissipate through respiration, sweating or active cooling. Rumination generates large amounts of heat, so when a cow is hot, her first response is typically to eat less feed.
Transition cows get a lot of attention as the transition period brings significant challenges. For dairy cows, the transition period is typically the last three weeks of gestation and the first three weeks of lactation, during which cows undergo a variety of metabolic and immunological changes that increase their susceptibility to metabolic disorders and infectious diseases.
