Researchers in Russia have successfully cloned a cow that will produce lactose-free milk. The project was conducted at the Skolkovo Institute of Science and Technology with help of scientists at the Ernst Federal Livestock Science Center in Moscow. The researchers took the cow’s genes and removed the beta-lactoglobulin (the protein which makes people lactose-intolerant).
The cow was cloned back in the spring of 2020 but was kept with its mother for the first year. Now the plan is to impregnate a herd of cattle with the beta-lactoglobulin-free embryos in hopes of creating a generation of cows that would naturally produce lactose-free milk.
