Level of protein for heifer calve wintered on bluestem pasture

Abstract

The 66 heifers used were good-to-choice Herefords purchased near Fort Davis, Texas, assigned to treatments on a random weight basis. The heifers were rotated between pastures to minimize any difference due to pastures during the first winter grazing period and the summer grazing period. Dicalcium phosphate was fed to standardize phosphorus intake between groups during the first winter grazing period.
