Thursday Industry Insight: Heat Stress in Cattle
Cheyenne Young – KRIRM Graduate Student
Heat stress is more than just mild discomfort. As temperatures rise, so does the risk of heat stress for cattle. It can seriously affect herd health and significantly impact production and profitability.
Cattle are less effective at sweating, making it harder for them to cool down compared to humans. They start experiencing heat stress earlier, particularly in humid environments. As their body temperatures increase, producers often see reduced feed intake, which results in lower weight gain. Additionally, heat stress can lead to decreased milk production in mother cows and impair fertility.
Signs of Heat Stress in Cattle
• Panting
• Drooling
• Reduced feed intake
• Crowding water sources
• Standing (instead of lying down)
In some extreme cases, heat stress can lead to death. At risk animals may have of a higher body condition score (BCS), darker hides, and lack access to clean water and shade.
Prevention is Key
To prevent heat stress, provide adequate shade and fresh, cool water. Avoid handling the herd during the hottest parts of the day and schedule feedings during cooler times.
Producers have a responsibility to be proactive. We should recognize warning signs and monitor the weather to protect the wellbeing of our animals.
Heat stress not only affects the animals but also impacts operational profitability. Be vigilant and prioritize the health of your herd this coming summer.
