Keep em lean…
SUMMER calving cows must be stocked very tightly on swards that resemble a golf course to stop them becoming too fat.
That is the advice of Scottish Agricultural College senior dairying speicialist Dr David Roberts. He warns that cows turned out to grass at 8-10cm will eat too much and become fat.
"Keep cows stocked tightly with virtually no grass in front of them," he says. His target sward height is about 2-3cm.
"Grass growth will be more than adequate, even though it wont look like it," he adds. For more on dry cow management, see page 40.
