Young dairy calves have a relatively low percentage of body fat and therefore require a diet with high amounts of energy early in life.

Calf milk replacer

To provide the higher levels of energy required for growth, the amount of calf milk replacer fed per day or the energy density of the CMR fed will have to be increased.

One option is to increase lactose levels, but this results in an increase of osmolality, which can be detrimental to the calf. LifeStart research has shown that calves fed according to LifeStart principles are better prepared to handle fat. Trials in which calves were fed an energised calf milk replacer (CMR) with increased amounts of fat have shown similar growth rates but better faecal scores and a lower incidence of dairrhoea for calves fed ECM compared to calves fed a traditional CMR.

Calf starter

Trials with en energised calf starter (ECS) containing extruded pellets with fat have resulted in additional weight gains.
