In Dairy Cows Texas summers are a challenge to managing dairy cows. The combination of high temperature and humidity is especially stressful to the dairy cow. The result is decreased feed intake, milk production, milk fat percentage, and reproductive efficiency. I. Feeding During Heat Stress Water, feed and shade are critical in managing heat stress.
Water helps regulate temperature.
As the temperature rises above 75oF, respiration rate increases and sweating occurs. This increases water loss from the lungs and skin. Therefore, an adequate water supply is essential. It should be conveniently located, clean, cool and preferably under shade. Try providing a water supply in the holding area of the parlor, at the exit from the parlor, and near the shade and feed to improve cow comfort and performance.
