They were able to keep the cows on pasture until Dec 18th when snow was at 25 cm. They pulled the cows in when they started to lose weight. A while ago, I read in Grass-fed Cattles by Julius Ruechel that even if cow's condition deteriorates a bit through winter, they will bounce back quickly on Spring's grass.
