Seven hundred sixty-two crossbred steers were used in a feedlot trial to determine the effect of V-Max® on performance, carcass characteristics, and the incidence and severity of liver abscesses. Finishing diets included either V-max® or the combination of Rumensin® and Tylan®. Performance was not different between the two treatments; however, including V-max® in the diet resulted in an increased incidence and severity of liver abscesses. Numbers of steers with small abscesses were similar between treatments; however, moderate and severe liver abscesses were increased in steers fed V-Max® compared to steers fed the combination of Rumensin® and Tylan®.
