Cattle Summer Welfare: Heat, Flies, and Pasture Management

Summer presents a cluster of welfare challenges for cattle including heat stress, fly burden, and pasture management issues that require proactive management to maintain good welfare.

Key Facts

Cattle at over 25C with high humidity experience heat stress affecting health and production
Cows naturally seek shade and will stand in water to thermoregulate
Black and dark-coloured cattle absorb more solar radiation and have higher heat stress risk
Fly burden peaks in July-August causing significant irritation and disease transmission
Pasture condition affects foot health, nutrition, and parasite burden in summer
Poaching of gateways and water points causes lameness if not managed

Welfare Considerations

Summer welfare challenges for cattle combine physiological stress from heat with constant irritation from biting flies and the physical hazards of poached gateways and overcrowded shade areas. Each of these factors causes genuine suffering measurable through behaviour and physiology. A proactive summer management plan addressing shade, fly control, water availability, and pasture rotation prevents welfare harm before it occurs.

What You Can Do

Ensure adequate shade provision for all cattle during summer
Provide multiple clean water access points to prevent competition and encourage drinking
Implement an integrated fly control programme before peak fly season
Rotate gateways and water points to prevent poaching and lameness
Monitor body condition score monthly to detect nutritional issues
Consult your vet about timing of anthelmintic treatments for summer pasture parasites
