Genetically Engineered Cow Produces Anti-Allergy Milk
Nowadays mothers are breastfeeding less, yet many children are allergic to a protein found in cow's milk. Researchers in New Zealand have successfully engineered a cow whose milk contains fewer of these proteins.
"In developed countries, 2-3 percent of infants are allergic to cows' milk proteins in the ﬁrst year of life," the researchers said in a paper published in the Proceedings of the National Academy of Sciences.
Anower Jabed and colleagues at the New Zealand government-run AgResearch company said their genetically modified cow produced milk with a 96 percent reduction in the protein beta-lactoglobulin (BLG), a component known to cause allergic reactions.
