Abstract

Crossbred, AI-pregnant heifers were fed in a Calan Broadbent individual feeding system for 110 days beginning at approximately day 142 of gestation. Heifers were offered ad libitum grass hay and no supplement, hay plus distillers based supplement, or hay plus dried corn gluten based supplement. Supplements were isocaloric, isonitrogenous, and equal in lipid content but differed in rumen undegradable protein. Protein supplementation increased DMI and ADG in pregnant heifers; however, calf birth BW and subsequent pregnancy rates were similar.
