The objectives of this experiment were to compare N fluxes of Optigen, a slowrelease NPN source, with urea; whether pelleting affects Optigen N release; and N source effects on ruminal fiber digestibility. Dietary crude protein treatments were soybean meal (SBM), ruminally dosed Optigen (OD), Optigen incorporated into a concentrate pellet (OP), or ruminally dosed urea (UD). Diets were 50% forage (oat hay; 5.5% CP, 66% NDF) and 50% pelleted concentrate feed. Dietary CP was higher for OD and UD diets than for SBM and OP (12.6 v 11.2%; P \u3c 0.01). Diets were fed to ruminally fistulated steers (BW 387 ± 28.9 kg) in a 4x4 Latin square designed experiment. Concentreate was fed and pulse doses of NPN occurred at 0800.
