Cattlemen's Day, 1983; Report of progress (Kansas State University. Agricultural Experiment Station); 427; Beef; Lutalyse®; Heifers; Dressing percentage
Lutalyse aborted 86.7% of heifers 40 to 100 days pregnant. Of four heifers tested at 101 to 150 days pregnant, all aborted. Open heifers gained faster (P<.05) than heifers that either were aborted or pregnant at slaughter. Those pregnant at slaughter had lower (P<.05) dressing percentages than either open or aborted heifers.
