Milk is a great source of calcium and protein. The main proteins available in this milk are whey and casein. Casein is the largest group of proteins found in milk which makes up about 80% of the total protein content. Herds that carry dominant traits for favorable milk proteins, such as Kappa-Casein A2 Beta-Casein, are dramatically increasing value for breeding and human nutrition. Beta-casein is one of six milk proteins and is produced by the CSN2 gene.

Xcelris Labs offers genetic testing to identify variants within the A1 and A2 groups thus providing a more detailed resolution of the beta casein gene in cattle. Our test would enable breeders to develop a diverse product basket with premium pricing to cater health conscious customers.
