Extract

The objectives of the experiment were:

  1. 1. To assess the suitability of antigen-free soya protein concentrate (SPC) and whey products as major ingredients and the sole protein source in milk substitute diets for calves.

  2. 2. To compare the effects of inclusion rates of 0, 350 and 700 g protein from SPC/kg dietary protein.

  3. 3. To investigate the suitability of introducing these diets to calves at 2 or at 16 days of age.

A fat-filled whey based milk substitute (diet WP1) was compared with similar diets in which SPC provided 350 g/kg protein (diet SK1J or 700 g/kg protein (diet SK2). Thirty-six Friesian bull calves were given one of these three diets reconstituted in water (1 powder:6 water w/w), offered at 38°C by bucket to appetite in two feeds daily, either at 2 days of age or after a 14-day period in which they were given a skim-based milk substitute (diet WP4).
