Unbelievable: A cow produces special milk for allergic

In the first two years of life, about 3 in 100 children suffer from milk protein allergy. While it made ​​the diagnosis, they stopped drinking cow's milk and powdered milk were prepared pacifier.

New Zealand researchers looking at the difficulties of not drinking this natural product they intended to produce a milk cow that does not contain the protein responsible for the allergy. They did not try to turn the milk, but made ​​a radical genetic modification of cows.

Based on cloning procedures they created the cow Daisy. It is the first that is genetically modified and produces a free beta-laktoglobuline the milk proteins that cause allergy in children. Change scientists cow cells by injecting a molecule that blocks the production of beta-laktoglobulines. Subsequently, the cell nucleus was introduced in an egg which had been removed the previous core. This was transplantua egg in the uterus of a cow.

However, scientists say the experiment is in its infancy and should still work given that hundreds transplanted egg was created only cow Daisy.
