July 2026 – Managing Heat Stress

Heat stress can be a major challenge with decreasing conception rates, chance of pregnancy loss, weight and performance loss, not to mention we simply don’t want our cattle to be uncomfortable. Bull fertility can also be affected. Remember, a suckler cow is under pressure trying to feed herself and her calf.

Here are a few key things to remember during the hot weather.

Here are a few key things to remember during the hot weather.

Cattle can intake 1.5 to 2 times their normal requirements for water during this time. Check your water sources, ensure there’s adequate access and availability for cattle.

Try to move cattle to fields with more shade/shelter. Can any housing be offered as shade alongside a field currently being grazed?

If you are moving stock try to wait until cooler times of the day, early morning or late evening. Avoid transporting animals where possible. The heat and wind from transport can dehydrate animals quickly.

Cattle need to be checked more frequently in hot weather. Look for signs of

• Panting
• Loss of appetite
• Dullness/Lethargy
• Huddling
• Reduced feed and water intake
• High body temperature
• In severe cases, collapse or death

Heavier cattle struggle with the heat more than lighter stock. Darker haired cattle suffer more also.

If you suspect an animal may be affected with heat stress, it’s vital to act quickly. Bring them calmly to shade, give them access to water, hose them down and call your vet if needed.

Flies are irritants, causing cattle to huddle which in turn increases their body temperature. Consider using Fly Control Tags, sprays or garlic licks.

Avoid working in peak heat hours, use suncream and keep hydrated.
