Researchers from the Siberian Branch of the Russian Academy of Sciences have found that breeding Yakut cows could provide a valuable source of omega-3 fatty acids in the population's diet. These fatty acids are recommended for preventing cardiovascular diseases. The study showed that Yakut cows have a unique composition of fatty acids in their meat and liver, making them a valuable source of omega-3 PUFAs and potentially reducing pressure on aquatic ecosystems for obtaining these acids.
