2. Three spray-dried powders were prepared after heating skimmed milk for 30 min at 60 deg (LT), 73.9 deg (MT) or 85 deg C (HT). Each was reconstituted to 2 concentrations of dietary fat and given to 5 or 6 calves for 26 days after purchase at about 1 week of age. Calves given the HT skimmed milk had significantly (p<0.05) higher incidence of diarrhoea and slower rate of gain over 19 days on test than those on the MT and LT milks.
