Skimmed milk, straight from the cow
Scientists have bred cows that produce skimmed milk and hope to establish herds of cattle meet the needs of consumers concerned about their health.
Milk is also rich in omega-3 fatty acids are said to improve brain power, and contains polyunsaturated fatty acids. Saturated fats are found in normal milk are linked to increased risk of heart disease. Cows, which have a mutation particular gene, were raised by a single female found by investigators when milk detection million cattle in New Zealand.
Butter these cows has spread further advantage of the fridge, like margarine.
ViaLactia scientists, the biotechnology company based in Auckland after £ 55 million research, have called the cow Marge. Russell Snell, ViaLactia chief scientist, said: "Marge looks like an ordinary Friesian cow but has three major differences. Produces a normal level of protein in her milk but substantially less fat and fat, there is a lot more unsaturated fat. It also produces milk with very high levels of omega-3 fatty acids. "
Marge was discovered in 2001 when researchers ViaLactia its owner bought for £ 120 and moved to a secret location.
The key question was whether her calves would inherit her traits. "You have to generate daughters and then have to carry a calf and deliver the milk," said Snell. At the time of Eureka was when he found his daughters produce milk like their mother. "The company says the first commercial herd could be in 2011. A brief Wilks ViaLactia is due to be published this week in the journal Chemistry and Industry, a journal of the Society of Chemical Industry. A work formal investigation of a peer-reviewed journal will continue. Sunday Times, London
The genes of cows bred for skimmed milk has not yet nailed
After raising cows that produce skimmed milk, ViaLactia scientists, the biotechnology company based in Auckland behind the research hope that the male offspring of the cow are the same genes as their daughters. "To have a progeny of bulls is going on Marge's face would be the Holy Grail. We will play hundreds of thousands of cows and Marge, "said Snell.
The Scientists are still trying to identify the genes that determine the characteristics Marge unique. Klaus Lehnert, 43, vice-Snell said: "We hope to find them. We are good at finding the genes. Then we can use DNA testing to see if an animal has the property, rather than relying on data from experiments. "
Milk was once universally regarded as a drink health, With heavy promotion by the government. Generations of children have grown up with slogans like "Drink a pint milka days." were care-free supplies school-age children and pregnant women. When questions started being raised about the fat content of milk, milk marketing in the past Office to try to sell the milk so sexy, targeting housewives with slogans like: "Is your man enough?"
Government health campaigns press and low-fat diets and sales of whole milk, butterfat containing 3.5, representing only 25 milk sales. In contrast, sales of semi-skimmed milk, containing 1.7 fat and skim milk, which has 0.1 fat account for 75 sales. Animals in New Zealand means they have less of a fat in their milk.
"The focus of New Zealand's exciting because people tend to avoid whole milk and go for semi-skimmed milk and skimmed milk. If whole milk can be done to contain fats saturated, which are good for you, people can go back to whole milk, Ed Komorowski, technical director of Dairy UK, said.
Dr Susan Jebb, head of the Unit Medical Research Council Human Nutrition, said that milk could contribute to the nation's health. "Dairy products make a contribution significantly to our consumption of saturated fat, which is 30 more than the recommended. A milk containing less fat and better type of fat, it would be much healthier. Tom Brooksbank, Norton & Brooksbank, one of the major breeding auctioneers UK companies and consultants, these animals can produce milk may be at a premium.
