Researchers created the animal using a technique that gives precise control over which genes are active within it.

A genetically modified cow whose milk lacks a substance that causes allergic reactions in people has been created by scientists in New Zealand.
In their first year of life, two or three in every hundred infants are allergic to a whey protein in milk called BLG. The researchers engineered the cow, called Daisy, to produce milk that doesn't contain the protein.
