Milk replacer is formulated to balance major nutrients (protein, fat and carbohydrates) with an optimal fortification of vitamins and minerals. When designing any nutrition program, the calf’s health, size and age must be considered. Historically, citations in scientific literature have documented trials where calves have been fed diets low in energy, depriving them of much-needed nutrition. Recent work has rightfully demonstrated that increased nutrition in the calf for optimized growth leads to many positive outcomes, including better milk output in the first lactation.
