We are transitioning into A2/A2 Genetics!
Unlike most dairies whose herds are bred for production, our herd was specifically bred for grazing. Our cows have a more natural lactation and produce less milk than your average dairy cow- about one-third of the milk on average. In a day, one of our girls will produce 35 pounds (or around 4 gallons) of milk. With less production than the average industry cow, every drop of milk is precious when it comes to nutrition, quality, and flavor. That is why we made the decision to transition into A2/A2 Genetics, making our high quality dairy products even better for you!
All proteins are long chains of amino acid. Beta casein is a chain 229 amino acids in length. Cows who produce this protein in their milk with a proline at number 67 re called A2 cows, and are older breeds of cows, such as Channel Breeds, (i.e. Jersey.) But some 5,000 years ago, a mutation-both natural & due to human intervention-occurred in this proline amino acid and began converting it to histidine. Cows that have this mutated beta-casein are called A1 cows, and include breeds like Holsteins, although it is possible through careful breeding and quality genetics to have Holsteins or Holstein Crosses produce A2/A2 milk.
We are currently testing our herd and finding that we already have many A2/A2 cows! Our last two testings came back at 70% and 75% A2/A2! When choosing sires for our dams, we are choosing high quality A2/A2 genetics from heritage and channel breeds of cows. When our ladies give birth to their calves, the heifers will grow and join in the herd, increasing our A2/A2 numbers until we are completely an A2/A2 herd!
