Description
In 7 trials, 200 SLB or SRB heifers taken in from pasture at least 3 weeks before calving were fed on a diet consisting of hay, lucerne silage and pressed beet pulp or hay and grass silage, plus oats, barley, beet feed and soyabean and rapeseed meals from 3 weeks before to 12 or 16 weeks after calving. Feeding programmes, plane of nutrition and experimental conditions varied among and within trials. Health assessment focused on hoof status after paring and (1 trial) blood values. Milk yield was about the same with medium or high concentrate intake in early lactation. With low concentrate supply before calving and high after calving some feed refusal occurred. On a concentrate-free diet before and after calving milk yield was low. Milk yield was higher and foot sole haemorrhaging commoner on concrete than on rubber matting. Yield and haemorrhaging also appeared to be linked in another trial. With higher concentrate intake insulin was increased at calving
