Abstract

A 33-day grain adaptation trial was conducted comparing wet corn gluten feed (WCGF; Sweet Bran®, Cargill) fed at decreasing levels (87.5% to 35%) to a traditional grain adaptation with decreasing forage (45% to 7.5%; CON) to test the effects on ruminal pH, dry matter intake (DMI) and in situ DM digestibility. Steers adapted by decreasing WCGF had greater DMI than CON (P < 0.01). During adaptation, DMI increased and ruminal pH decreased across both treatments. Steers adapted using WCGF had greater in situ DM digestion than steers adapted using CON. Diets containing WCGF had greater DM digestibility than diets containing forage, whether incubated in either CON or WCGF fed steers. Decreasing WCGF inclusion instead of forage is a viable method for adapting feedlot cattle to high-concentrate diets.
