Abstract
3 groups of 8 cows were fed during the dry period to achieve body condition scores of 1.5-2, 2.5-3 or 3.5-4 at calving; for 16 wk after calving all cows received the same complete diet. There was no difference between groups for peak milk yield (29 kg/day) or wk of peak (wk 6); lactation curves were also similar. It is concluded that fatter cows took longer to reach a lower peak intake because of their better body condition, and that more of their milk energy came from body fat.
