Jersey cows
Synonyms for A2A2 milk
The Jersey cow is distinguished by a naturally higher frequency of the A2 gene compared to other dairy breeds. This gene allows for the exclusive production of A2 beta-casein, a protein associated, according to several American and Australian studies, and numerous testimonies, with easier digestion for those suffering from lactose intolerance. Studies have shown that A2 beta-casein is less likely to release the BCM-7 peptide during normal enzymatic digestion. The latter is often associated with various disorders, such as lactose intolerance, digestive problems, cardiovascular disease, and type 1 diabetes.
A1 and A2: the differences
In Canada, the majority of dairy herds are made up of Holstein cows, whose milk contains the A1 gene. This is reflected on grocery shelves, where the majority of dairy products are made from this milk. At Missiska, our dairy products are made exclusively from milk from the Jersey cows in our herd. Not only can we easily certify the traceability of our products, but our farm milk also retains the hallmark of its exceptional quality.
Learn more about A2 milk
Did you know? Milk contains several nutrients, including a key protein: beta-casein, which comes in different forms. The most common are types A1 and A2. Interestingly, type A2 beta-casein is the original protein in cattle. Research suggests that the A1 variant appeared as a result of a natural mutation thousands of years ago. Therefore, the ancestors of today's cows produced only type A2 milk.
Origin of A2 milk
Preliminary research conducted by American and Australian teams on A1 and A2 milk proteins shows that they behave differently during the digestive process, due to a variation in the amino acid chain. The studies showed that A2 beta-casein is less likely to release the BCM-7 peptide during normal enzymatic digestion. The latter is often associated with various disorders, such as lactose intolerance, digestive problems, cardiovascular disease, and type 1 diabetes.
A2A2 Cows
To produce exclusively A2A2 milk, a cow must inherit the A2 gene from both parents. The advantage of choosing milk from Jersey cows is that they predominantly exhibit the A2A2 genotype.
Choosing A2A2 milk means choosing a product closer to its natural origin, recognized for its digestibility and potential benefits.
