Cattle Performance

Abstract An experiment was conducted to evaluate the effect of grain type and wet distillers grains inclusion on finishing cattle performance and carcass characteristics. Yearling steers (n = 320; initial BW = 325 ± 23 kg) were utilized in a 2 x 2 factorial arrangement, with the first factor as grain type at either 100% dry-rolled corn or a 50:50 blend of dry-rolled wheat and dry-rolled corn, and the second factor as wet distillers grains plus solubles (WDGS) inclusion at 12 or 30% of diet DM. There were no interactions between grain type and WDGS inclusion levels (P ≥ 0.21), contrary to our hypothesis that 50:50 wheat blend would improve performance with increased WDGS. There were no differences in DMI, ADG, or G:F (P ≥ 0.29) between 100% DRC or 50:50 blend of DRC and wheat. There was no difference in HCW between grain types (P = 0.84), but LM area was greater (P = 0.02) for steers fed a 50:50 blend of DRC and wheat. There were no differences in 12th rib fat or USDA marbling score between grain types (P ≥ 0.15), but increased LM area in steers fed the blended diet led to improved calculated yield grade (P = 0.04). Increasing WDGS in the diet increased carcass-adjusted final BW (P = 0.03) and improved carcass-adjusted ADG and G:F by 3.8% (P ≤ 0.05). Feeding 30% WDGS increased HCW by 10.9 kg (P = 0.03) and increased 12th rib fat (P = 0.02) compared to feeding 12% WDGS. There were no differences in LM area, USDA marbling score, or calculated YG between WDGS inclusions. These data suggest that increasing WDGS in the diet improves performance regardless of grain type and depending on price, wheat can replace up to 50% of the grain portion of the diet without affecting performance.

Urea Inclusion

Abstract Crossbred beef steers (n = 384) were utilized to evaluate the effects of adding urea to a dry rolled corn based finishing diet containing low inclusions of wet distillers grains plus solubles (WDGS). Treatments were set up as a 2 × 4 factorial arrangement with factors consisting of WDGS inclusion at either 12 or 20% of diet dry matter (DM) and urea inclusion at either 0, 0.4, 0.8, 1.2% of diet DM. Cattle were blocked and stratified by initial body weight (BW) and assigned randomly to treatment. The heavy block of cattle were harvested after 160 d on feed (DOF) and the middle and light blocks of cattle were harvested after 179 DOF. The model include the fixed effects of weight block, WDGS inclusion, urea inclusion, and their interactions. There were no significant interactions (P > 0.12) observed between WDGS inclusion and urea inclusion in the diet; therefore, only main effects are discussed. Increasing inclusion of WDGS improved (P < 0.04) carcass adjusted ADG and G:F. Dry matter intake was reduced (P = 0.04) with increasing WDGS inclusions. Fat thickness was increased (P = 0.04) with increased WDGS inclusion; however, no other carcass characteristics were significantly affected by WDGS inclusion. Cubic effects of urea inclusion were observed (P < 0.05) for HCW, final BW, ADG, and DMI on a carcass adjusted and live BW basis; however, cubic effects with increasing urea inclusion are of minimal biological relevance. There were no linear or quadratic responses (P > 0.11) for increasing urea inclusion in the diet for performance measurements or carcass characteristics. Increasing WDGS inclusion in the diet improved performance. Added urea in the diet had minimal impact on performance, regardless of wet distillers grains plus solubles inclusion.
