Dairy cattle can be affected in many ways by various types of stressors in their lifetime. Some of these stressors include temperature, living conditions, feeding management and others (Villamediana, 2022). The stress can cause a cow to have a decreased milk production, changes in body weight, increased risk of infections, diseases, and others.

As summer heats up, water becomes more important for cattle. An animal’s body is comprised of 70% water and adequate water consumption is required to maximize performance. It’s no secret that withholding or restricting water can decrease feed intake and reduce gains. Yet many producers often forget to assess whether or not their animals have optimal access to high quality water. An animal’s water requirement is met through consumption of feed and drinking. Many feeds, such as silage and grasses, contain a large proportions of water that help cattle meet their water requirement. Additional requirements are met through drinking.

There is no question that heat stress can negatively impact animal performance. Exposure to heat stress reduces daily gains, milk production, and reproductive efficiency, though specific impacts on production varies depending on the magnitude and duration of heat exposure. Prolonged exposure to heat stress is much more detrimental than short-term heat stress and its effects linger long after temperatures drop back below the heat stress threshold.
