By-products can be used as alternatives to the feed ingredients normally used in dairy diets.

In the August 2012 California Dairy Newsletter, Alejandro Castillo with the University of California Cooperative Extension- Merced County discusses the main nutritional concerns of using by-products, including:

  • Possible mycotoxin contamination
  • Mineral content
  • Excess dietary fat content
  • High moisture level feeds
  • Excess or deficit of fiber
  • Palatability
  • Crude protein content
  • Animal performance
