Each 1st feeding of TMR was fed to a clean bunk as bunks were cleared of all residual feed, which was weighed daily by pen, immediately prior to the 1st feeding. Weights for each load of TMR fed were recorded on record sheets at the time of feeding and used together with daily refusals to calculate DM intake per cow/pen. The “TMR tracker” system (Digi-Star LLC, Fort Atkinson, WI, USA) kept a record of the actual ingredient profiles of each batch of TMR mixed.
