Researchers at the Krasnodar Center for Animal Science and Veterinary Science, operating under the Russian Ministry of Education and Science, have developed a herd of cows whose milk does not provoke adverse reactions in the gastrointestinal tract. They have also created a highly sensitive testing system to quickly identify milk that could cause such reactions. The Ministry shared these developments with socialbites.ca.

Milk contains the beneficial protein β-casein, which can occur in two main variants: A1 and A2. The two forms differ by only a single amino acid. The A1 form has been linked to inflammatory responses in the body, while the A2 form is generally better tolerated and absorbed. The World Health Organization notes that about 30 percent of the global population may experience adverse gastrointestinal reactions to milk and dairy products containing A1. In contrast, milk that contains only the A2 variant is typically well absorbed and can contribute positively to digestion and comfort. (Citation: World Health Organization)
The ratio of A1 to A2 β-casein in milk is determined by the cow’s genotype. Through the new technology, a herd has been produced that yields milk composed solely of the A2 form, which is easier to digest for many people. This development has enabled the Krasnodar Territory to start producing A2-type dairy products, including yogurt, sour cream, cheese, and cottage cheese with a higher concentration of casein.

The milk type can be identified quickly with the newly developed testing system. The approach is straightforward and cost-effective, enhancing the feasibility of adopting A2 milk broadly. (Citation: Krasnodar Center for Animal Science and Veterinary Science)
It is noted that determining a cow’s genotype costs around 600 rubles. The testing and genetic assessment can be conducted in most veterinary laboratories equipped with basic instruments such as a centrifuge, a thermal cycler, and an electrophoresis setup. This information was provided by the Ministry of Education and Science through socialbites.ca. (Citation: Ministry of Education and Science)
Earlier statements from some sources claimed the existence of brands offering sour cream without dairy fat. These claims are acknowledged here to reflect past discussions and do not reflect current technology or product composition in this program. (Citation: Industry Reports)
