During early gestation (for 16 weeks roughly from October to January) digestible energy (DE) is level just under 4.0 Mcal/d. DE climbs during February until it hits approximately 6.5 Mcal/d. During early lactation (8 weeks for March and April) DE stays level at 6.5 Mcal/d. In May DE drops drastically and stays level at 2.0 Mcal/d during the dry period (16 weeks from May to August). DE begins to climb during September and the cycle starts again.
