Supplementing beef calves grazing cool-season annual grass with warm- or cool-season grass hay (0.4% liveweight), differing in cell wall content, depressed weight gain more by heifers than steers. Adding supplemental corn (0.8% liveweight) to hay only improved gain by heifers, though gain was not greater than controls for either gender. Key words: Cattle, beef, supplements, pasture, corn, hay
