Researchers in New Zealand have discovered a cow that innately produces milk with a fat content of about 1 percent. Several of the cows’ daughters also possess the gene to produce low-fat milk. Now, through breeding, they are working to develop a herd of cows that will naturally produce low-fat milk. The researchers say the milk from these animals is also high in omega-3 oils, which is beneficial for heart health. However, it will be several years before the herd will be large enough to produce milk on a commercial basis.
