Summary

A comparison was made of beef-type and dairy-type suckler cows in 17 herds by forming pairs when cows of both types calved within 7 days of each other in the same herd. Cows and calves were weighed within 14 days post partum and when turned out to grass. The calves were weighed again at weaning. Winter food intakes were recorded by weighing feeds on one day of each month. Sixtynine pairs of cows were formed and 23 different levels of winter food input to the cows were computed.

Calves out of dairy-type cows were significantly heavier at turn-out (8-4 kg) and at weaning (8-3 kg). These differences were greater at higher levels of winter food intake per cow.
