The A2 Beta-Casein has been getting a lot of attention lately, especially in the dairy industry. GeneSeek defines it as follows:

The solids found in cow’s milk are composed of fat, protein, lactose and minerals. Beta-casein is one of six milk proteins and is produced by the CSN2 gene. Twelve genetic variants of CSN2 are known which cause changes of certain amino acids in the beta-casein protein and alter its properties. These variants can be classified into two groups (A1 and A2) which code for different amino acids at one specific site in the gene. Milk containing A2 beta-casein is considered to have health benefits for nursing calves and for human consumption.

More simply, the A2 beta-casein is a milk protein that contributes to the nutritional value of the milk. An A2/A2 cow can theoretically raise a bigger calf on less milk than an A1/A2 or A1/A1 cow. This may be one reason our moderate-sized, low-input PCC cows can raise big calves without being heavy milkers. This may be the next big Game Changer in this business!

Why haven’t we heard about this from other bull studs and bull producers? To be blunt, they are not interested in efficient, moderate-sized, low-maintenance cattle. As farmers and ranchers, we need to be looking for every advantage we can get to increase our profitability. The A2 beta-casein is just that, another edge. You can take it or leave it.

We have reason to believe a high percentage of PCC cattle are A2/A2. We have tested all of the PCC AI sires and are in the process of testing our sale bulls for A2/A2. Stay tuned as we share the results over the next couple of weeks. This is leadership in action!
