In a more recent investigation (Lunt et al., 2005; Chung et al., 2007), a group of steers was fed a corn-based finishing diet to achieve a growth rate of 1.36 kg/d for 8 mo (short-fed, corn-fed), or were fed a hay-based diet supplemented with the same finishing ration to achieve a growth rate of 0.9 kg/d for 12 mo, with a targeted final BW of approximately 525 kg (short-fed, hay-fed).
