Our objective was to determine the extent to which a stair-step compensatory nutrition regimen regulated the growth and subsequent lactation performance of developing beef heifers. Forty crossbred beef (Angus × Gelbvieh) heifer calves were assigned to either a control or stair-step compensatory nutr...
