What are milk proteins? Milk is composed of water, lactose, fat, proteins, and minerals. Beta Casein A2 and Kappa Casein are two of the six proteins found in cows' milk and are associated with digestibility and cheese yield.
The A2 variant of Beta Casein A2 is associated with increased digestibility for about 25% of the population. Anecdotal evidence and data from several small human studies indicate that about 1 in 4 people are sensitive to the A1 protein, and drinking milk or eating dairy products from A1/A1 or A1/A2 cows can cause digestive upsets. (Read my CowTales post, What is A2 Milk?, to learn more about Beta Casein A2.)
When bred with an A2/A2 bull, Shirley Rose's calves will have a 50% chance of being A2/A2 and a 50% chance of being A1/A2. When bred with an A1/A2 bull (like Showdown), her calves will have a 25% chance of being A2/A2, a 50% chance of being A1/A2, and a 25% chance of being A1/A1.
The A variant of Kappa Casein is associated with higher milk production; the B variant is associated with improved rennet coagulation properties and increased cheese yield and favoured by cheesemakers.
