In 2011, using human cloning for the first time, human genes were introduced into more than 300 cows in China. Today, genetically modified animals graze on a pasture near Beijing. At first glance, they are no different from the usual "cows", they are black and white, Holstein races, but in reality they are experimental objects, the result of the activities of dreamers-scientists.
The first step in the effort to produce milk with human properties, but produced by animals, was made in 2011. All this to create an alternative to breastfeeding and modified milk. The scientists dream is to produce milk as perfect as possible, close to human composition.
What has been achieved in this topic so far? It turns out quite a lot. The introduction of "new milk" is already planned. Within 4 years, "human milk" produced by cows is expected to appear on the market. Before this happens, volunteers will be tested soon enough to check the effects of the milk on themselves.
Why are attempts to refine a new drink that, according to the creators, has 80% human properties right now, are repeated in China? Well, because here the rules for the production of genetically modified food are not as restrictive as in the European Union.
What do Chinese Moms Look About? They have divided opinions. Many do not believe the new Chinese "invention." Like modified milk. It was in China in 2008 that hundreds of thousands of Chinese babies became poisoned by a poison melamine melanoma, and six of them died of it.
In addition to Chinese studies, Argentine studies are ongoing. Also in Argentina, cows producing milk with human proteins are cloned ...
Human proteins in cow's milk
What did the scientists from China do?
Until now, the following ingredients characteristic for mother's milk have been introduced into cow's milk: lysozyme - cationic protein that protects against bacterial infections during the first days of life, lactoferrin, which corresponds to the increase in the number of cells of the immune system in children and alpha-lactalbumin - a nutrient that does not cause allergies in mother's milk.
Scientists already know that milk with human properties provided by genetically modified cows is more pronounced in taste, according to them is also sweeter and tastier. It can also be beneficial to animals due to its antibacterial properties - they argue.
Good idea or not?
The authors of the experiment, including Professor Li, the main coordinator of the work, do not wonder if his actions are ethical. Indicates that 1.5 billion people are not eating anywhere in the world. That is why he sees his duty in developing science and technology.
At one forum, the idea of producing human milk by genetically modified cows was considered terrifying: "A cow gives human milk, a guy thinks she is a woman, oscypek must have an EU sticker, and the banana has a proper fold. Dolphins are so cute, they want to marry one of them, they are a mammal. Who will forbid me? "
The controversy is also fueled by the fact that 42 "modified" calves were born, but only 26 of these animals survived. Ten died shortly after birth, mostly due to gastrointestinal diseases, and another six died within six months of birth.

There are ongoing protests in Europe against the introduction of new milk. Opponents argue that testing for a new drink should be done on a larger scale, just like when a new drug is introduced.
And what do you think about it?
