Scientists are breeding cows that can produce skimmed milk and butter that is so soft it spreads straight from the fridge.

A team in New Zealand have identified a cow, named Marge, which naturally produces lower levels of saturated fat in her milk.

They believe her unusual characteristics could be bred into other herds so delivering low-fat milk that is healthy and tasty.

Not only could these cows produce “natural” skimmed milk but the low-fat content will create butter that does not become a solid brick when put in the fridge.
