What is different about the milk produced by AgResearchs transgenic animals compared to milk from ordinary animals?
Milk from some of the transgenic herd contains a human protein that does not exist in milk from ordinary dairy cows. This protein is present because of genetic modification prior to the breeding of the first animals in AgResearchs transgenic herd. Research has demonstrated that the modification that produces the proteins is retained through successive generations, and that the protein could be extracted, purified and used to produce pharmaceuticals to combat disease in humans.
