Category: Cow breeds

The fat percentage in cow's milk varies significantly by breed, with a Holstein's milk typically containing about 3.7% fat, which is among the lowest of the major dairy breeds. This variation is a key factor for consumers interested in low-fat dairy products and for farmers aiming for specific milk compositions.

The majority of commercially available dairy milk in countries like the United States, Australia, and much of Europe contains both A1 and A2 beta-casein proteins. This mix is largely due to the widespread use of certain cow breeds, leaving many to wonder, "Which cow's milk is A1?" The answer lies in the genetic makeup of the dairy cattle itself.
