Breeding cows for milk is useful for users' health

By genetic modification, Chinese scientists have successfully developed two new dairy breeds, one that can produce milk with less lactose and one that contains more Omega-3 fatty acids.

Geneticists in Inner Mongolia University have added a gene from the archaea (Archaea scientific name) to the embryo of the cow. This gene is able to break down lactose (the type of sugar found in dairy products) into more easily digested sugars, which can be used for people with lactose intolerance - often with diarrhea and pain. abdomen, bloating after using milk-containing food.

A total of 14 embryos have been formed and transplanted back into the womb of the cow. Of the five calves born in April, three had the gene needed to produce milk with less lactose. When they mature and give milk, experts will conduct tests to accurately assess their lactose content in milk. If convenient, low-lactose milk will be available in the market for at least 5 years.

Meanwhile, another research group from Inner Mongolia University said it has also created a genetically modified cow breed for milk containing high levels of Omega-3 fatty acids. This acid is a good nutrient for the cardiovascular and mental system, which is found only in oily fish such as tuna, tuna, star anise . The research is published in Springer's Transgenic Research magazine. (Virtue).
