AN263: Importance of Milk Feeding Pre-weaning to Dairy Calves

Figure 1. Caloric and protein needs for calves of different body weights to maintain their weight. Calculated based on the metabolizable energy (megacalories per day) and digestible protein (grams per day) using NRC (2001) and Davis and Drackley (1999). Arrows indicate that for a 100-lb calf, the caloric need for maintenance of body weight is 2.1 Mcal/day, which is equivalent to 1 gallon containing 1 pound of reconstituted milk replacer powder.
