A University of California-Davis study finds that byproduct feeds are a major part of California dairy rations, with more than 70 distinct byproducts used on farms. The 2019 survey found 97% of milk cows in the San Joaquin Valley were on dairies feeding byproducts.
Heavy reliance on byproduct feeds means dairy demand for these ingredients stays structurally strong, supporting byproduct values in California. The analysis is background rather than a new price-moving event.
