Dairy Cow Heat Stress: Nutrition and Feed Additive Support
Heat stress can reduce feed intake, alter rumen activity, affect reproduction and lower milk performance. A practical response starts with shade, ventilation, clean water and feeding management.
Nutrition priorities in hot weather
Keep fresh feed available, reduce feed heating, protect forage quality and provide easy access to cool water. Rations may need review for energy density, fiber, minerals and electrolyte balance. Changes should be made with a qualified nutritionist.
How additives may help
Vitamin and mineral products, electrolyte support, rumen conditioners and targeted energy products may fit into a heat-stress plan. Their value depends on the existing ration and the severity of the challenge. Additives cannot replace cooling and water management.
What to monitor
- Feed and water intake.
- Milk yield and milk components.
- Rumination and manure consistency.
- Body condition and reproduction indicators.
