ABC Science: GM cow produces allergy-free milk
New Zealand researchers have genetically engineered a cow to produce milk free of the protein that causes allergies in children.
The milk could also prove to be healthier than normal milk as it contains higher levels of the protein casein, which would result in higher calcium levels and improved cheese yields from the milk.
The development targets the 2 per cent to 3 per cent of infants in the developed world who are allergic to cows' milk proteins - used in the production of baby formulas - in the first year of life.
The researchers add that the success of their approach suggests it may also be used to alter other traits in livestock. ...
