Stilbestrol implants for steer calves on a wintering, grazing, and fattening program; the value of Aureomycin during the wintering and fattening periods

Abstract

The Hereford steer calves used in this experiment were assigned to experimental lots randomly according to weight. They originated near Paducah, Texas, and graded USDA Good as feeders. All received the same basic ration from December 1, 1958, to April 28, 1959. They were grazed on bluestem pasture from April 28, 1959, to July 24, 1959, and were self-fed grain on grass from July 24 to November 14, 1959.
