More Water = More Milk

Researchers at leading institutions, such as Michigan State University, have proven that water is a critical component for dairy farmers for three main reasons.

1. Milk Content

Milk is comprised of 87% water. Because of the high water content, the amount of milk a cow produces is directly related to the amount of water in her body. Therefore the more water a cow consumes, the more milk she will be able to produce as indicated by the white angled line in the graph below.



2. Feed Habits

Milk production is also directly related to a cow’s nutritional intake and absorption, which is directly related to how much water she consumes. If she is drinking maximum amounts of water, she will eat more as indicated by the green line in the graph above, thus producing more milk with increased butterfat content.


3. Animal Health

The overall health of a cow subsequently affects her milk production. When water is impure, even small amounts of contaminated water can compromise animal health. And when a cow is struggling with illness, her milk production decreases.
