This study evaluated performance and diet digestibility of weaned calves fed starters with 2 types of corn processing and 2 levels of heat-treated soybean meal (SBM). The 4 starters used were whole corn (WC) with conventional SBM (CS; 25% of diet as-fed), WC with a 55:45 blend of CS and SoyPass® (LignoTech USA; SP), flaked corn (FC) with CS, and FC with SP. Starters were texturized (35% corn, 35% protein pellet, 27% whole oats, and 3% molasses) and formulated to be equal in CP (20%), starch (44%), and NDF (17%) on a DM basis. Calves were previously fed one milk replacer (26% CP, 18% fat on DM basis) at 0.66 kg DM for 39 d then 0.33 kg for 3 d and received the same starter treatments. Ninety-six male Holstein calves (77.6 kg initial BW) were grouped by previous starter treatment (4 calves/pen) and fed a 95% starter, 5% chopped grass hay diet (as-fed basis) for 56 d. Pen intake was measured daily and BW, hip width (HW), and body condition score (BCS) was measured every 28 d. From d 27–30, fecal samples were taken from the pen floor and composited by pen to estimate diet digestibility. Data were analyzed as a completely randomized design with pen as experimental unit and block as a random variable. No interactions of corn processing and heat-treated SBM were observed for performance or digestibility estimates. Overall, BCS change was less (P = 0.04) and HW change tended to be less (4.5 vs. 4.7 cm; P = 0.07) for calves fed FC vs. WC. Digestibility of starch was greater (97.8% vs. 95.4%; P = 0.01) and NDF digestibility was lesser (49.8% vs. 57.4%; P = 0.02) for calves fed FC vs. WC. Other digestibility measurements did not differ. In this study, increased corn processing moderately improved starch digestibility but reduced fiber digestibility substantially and did not increase growth or feed efficiency. Additionally, using bypass SBM did not improve performance or digestibility estimates. It does not appear that increasing grain processing or including more bypass protein results in better energy or protein utilization in calves under 4 mo of age but would increase feed costs.
