Abstract

Feeding dairy calves a higher plane of nutrition (PON) through either greater quantities of milk solids or fluid volume has become increasingly common on commercial operations. Administering more nutrient-dense milk rations may compromise the functionality and environment of the abomasum, potentially resulting in clinical abomasal pathologies. The objectives of this experiment were to determine the effects of PON on the abomasal environment in healthy Holstein calves.
