Water is the most important nutrient and the least costly nutrient for lactating dairy cows. Dairy cows need 4-5 pounds of water to make 1 pound of milk.
It is important to provide water in each paddock when cattle are on pasture. This investment in labor and cost may pay for itself quicker than almost any other management practice on the farm, says J. Craig Williams, Penn State extension educator.
In the latest issue of Penn State's Dairy Digest newsletter, Williams takes a look at this topic. In particular, he discusses the following points:
- Dairy cattle water needs
- How to determine tub and pipe size with flow rates
- Water pipe sizing
- Does it cost or pay?
