There was an approximate 40 percent reduction in on-farm water use in 2014 compared to 1964. Improvements in milk equipment such as vacuum pumps and plate coolers were responsible for a large portion of the on-farm water use savings.
Approximately 40 percent of dairy feed ingredients in California come from byproducts of other agricultural and food production industries. As a result, approximately 40% of the feed needed to produce California milk—which represents about 20 percent of all U.S. milk—is being provided without additional water.
In addition, by implementing water saving crop rotation techniques, dairy farmers are providing critical wildlife habitat to species that depend on these croplands – including the tricolored blackbird – an endangered species now afforded sustainable habitat through these new techniques.
