Heat Stress in Dairy Cattle
When temperatures rise, dairy cattle often reduce feed intake and spend more energy coping with heat. That can quickly affect milk yield, rumen function, fertility and overall comfort.
Practical management starts with water availability, shade and airflow, while nutrition should be reviewed for changes in intake, mineral balance and ration density. Feeding times can also be adjusted so more of the daily ration is consumed during cooler periods.
What to focus on
For farms in hot climates, the objective is not one isolated intervention. It is a coordinated approach that combines environment, water, feeding management and a ration designed around the animal’s changing intake and metabolic needs. Regular monitoring of intake, milk production, manure consistency and body condition can help identify problems early.
