Extract

Previously reported results (Wicks et al., 2005) indicated growth rates from birth to day 28 increased when level of milk replacer feeding was increased from 600 to 1200 g/d, but that there was no increase when milk crude protein content replacer was increased from 230 to 300 g/kg (Wicks et al., 2005). Calf starter concentrate intake decreased with increasing milk replacer feeding and calves offered 1200 g milk powder/d at concentrations of 120 g powder/l water did not consume their whole allocation of milk replacer. The objective of the current study was to establish the optimum level of inclusion of milk replacer and to evaluate the effect of an intermediate protein concentration i.e. between 230 and 300 g/kg.
