Summary

1. Four British Friesian steers were reared to a live weight of 340 kg as pre-ruminant animals, by the use of milk substitutes based on liquid skim milk, spray-dried whey powder and an ultra-high-fat (68%) milk powder.

2. Except for one case of hypomagnesaemia, the steers remained healthy. Live-weight gain/day, age at slaughter and feed conversion ratio were 1·23 kg, 253 days and 2·31 kg dry matter/kg weight gain respectively.

3. No marked development of the rumen had occurred; gut fill in relation to fasted live weight was 3·4% and killing-out percentage was 61·2.
