Two studies were conducted to evaluate field peas and wet or dry corn distillers grains with solubles (WDGS and DDGS, respectively) in finishing and growing diets. In Exp. 1, British crossbred steers (n = 352, initial BW 356 ± 27 kg) were used in a randomized block design with factors being 0 or 20% field peas and 0 or 30% WDGS in dry-rolled corn (DRC) based finishing diets (DM basis). There was an interaction (P < 0.01) for DMI and G:F. Feeding WDGS increased ADG (P < 0.01), whereas peas had no effect on ADG (P = 0.33). Including WDGS increased G:F in diets without peas (P < 0.01), but had no impact (P = 0.12) in diets containing peas. Peas increased G:F (P = 0.04) in diets without WDGS, but decreased G:F (P = 0.03) with WDGS. Feeding WDGS increased HCW (P < 0.01). In Exp. 2, Continental crossbred heifers (yr. 1; n = 108, initial BW 338 ± 14 kg) and British crossbred steers (yr. 2; n = 90, initial BW 321 ± 10 kg) were assigned randomly to 1 of 9 pastures. Treatments were supplementation with loose DDGS meal on the ground (GROUND), in a bunk (BUNK) or a 25% field peas, 75% DDGS cube on the ground (CUBE) at equal CP. Final BW and ADG were less (P < 0.01) for GROUND than for CUBE and BUNK, which were similar. These data indicate up to 50% DRC could be replaced by peas and WDGS, and peas are an acceptable binder for DDGS range cubes.
Effects Of Dried Distillers Grains And Equivalent Undegradable Intake Protein Or Ether Extract On Performance And Forage Intake Of Heifers Grazing Smooth Bromegrass Pastures, J. C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson, W. A. Griffin

Crossbred heifers (n = 120; BW = 368 kg, SD = 39 kg) were used to determine effects of dried distillers grains (DDG) and relative contributions of undegradable intake protein (UIP) and fat (ether extract, EE) in DDG on ADG and forage intake (FI). Heifers rotationally grazed six 3.5-ha, smooth bromegrass paddocks (IVDMD = 65.7%, CP = 20.8%, UIP = 2.17%, DM basis). Heifers were blocked by previous ADG and allotted to treatments in a 3 × 3 + 1 factorial design. Factors were source and level of supplementation. Supplements were as follows: 1) DDG (UIP = 15.8%, EE = …

The objective of this study was to determine if feeding carbohydrate supplements with faster degradation rates than corn to dairy cows grazing ryegrass would improve nitrogen capture, milk production, and components. Treatments were grain supplements based on: 1) corn (CORN), 2) barley and molasses (BM), or 3) citrus pulp and molasses (CM). For BM and CM, the diet composition was the same as that of CORN except that a portion of the corn was replaced with barley and molasses or citrus pulp and molasses, respectively, on a dry matter basis. Cows grazed ryegrass (Lolium multiflorum Lam.) pasture. Yield of …
