Skimmed milk, straight from cow

Scientists have bred cows that produce skimmed milk and hope to establish herds of the cattle in order to meet the demands of health-conscious consumers.

The milk is also high in omega-3 oils, claimed to improve brain power, and contains polyunsaturated fat. The saturated fats found in normal milk are linked to increased risk of heart disease. The cows, which have a particular genetic mutation, were bred from a single female discovered by researchers when they screened milk from millions of cattle in New Zealand.

Butter from these cows has the extra advantage of being spreadable straight from the fridge, like margarine.

Scientists at ViaLactia, the Auckland-based biotech firm behind the £55 million research, have named the cow Marge. Russell Snell, ViaLactia’s chief scientist, said: “Marge looks like an ordinary Friesian cow but has three key differences. She produces a normal level of protein in her milk but substantially less fat, and the fat she does produce has much more unsaturated fat. She also produces milk with very high levels of omega-3 oils.” Marge was discovered in 2001 when ViaLactia’s researchers bought her from her owner for £120 and moved her to a secret location. read more....
