WELLINGTON, New Zealand (AP) - New Zealand scientists are breeding a herd of cows that produce lower-fat milk after the chance discovery of a natural gene mutation in one animal.
Milk from the cows is also high in health-boosting omega-3 fatty acids and makes butter that spreads as easily as margarine even when chilled, biotechnology company Vialactia said Monday.
Scientists discovered a cow, later named Marge by researchers, carrying the mutant gene in a dairy herd they were testing in 2001, Vialactia chief scientist Russell Snell said.
