Effects of ABVista yeast (S. cerevisiae) on apparent total tract nutrient digestibility of DM, OM, starch, CP, and EE in natural-program beef steers fed steam-flaked corn-based finishing diets. Except for starch (P = 0.55; SEM = 0.06; n = 12), all nutrients showed a quadratic increase (P < 0.01; SEM = 0.70; n = 12) for the LY treatment over CTL and HY treatments. Although the LY had greater apparent total tract nutrient digestibility than both HY and CTL, the HY treatment also had greater digestibility of all nutrients except for starch and EE vs. the CTL treatment (P < 0.01; SEM = 0.49; n = 12 pens per treatment).
