Abstract This study examined the effects of altering ruminal fermentable carbohydrate (RFC) supply by feeding different amounts of corn and wheat in finishing cattle diets containing 15% corn dried distillers grains [DDGS; dry matter (DM) basis] on ruminal fermentation characteristics and nitrogen (N) utilization. Six ruminally-cannulated crossbred heifers were used in a replicated 3 × 3 Latin square design with 28 d periods. Dietary treatments were either corn (73% of diet DM; CON), 53:20 corn:wheat blend (20W) or 33:40 corn:wheat blend (40W) as the major fermentable carbohydrate source. Diets were isonitrogenous (12% CP; DM basis). Feed intake was measured daily. Indwelling pH logger were used to measure ruminal pH (d 22 to 28) and ruminal fluid was collected from d 26 to 28 to determine fermentation characteristics, as were feces and urine to measure N excretion. Data was analyzed using PROC MIXED in SAS. Dry matter and N intake tended to be lower (P ≤ 0.07) for heifers fed the 40W compared to the CON and 20W diets. There was no diet effect (P = 0.15) on total VFA concentration; however, the duration and area for pH < 5.5 tended to be longer (P = 0.07) and greater (P = 0.096), respectively, for heifers fed the 20W and 40W compared to the CON diet. There was no diet effect (P ≥ 0.44) on ruminal ammonia concentration and total urine N excretion (g and % of N intake). However, urine urea N (UUN) excretion as a percentage of total urine N tended to be lower (P = 0.05) in heifers fed the 20W and 40W compared to the CON diet. In summary, although altering RFC supply by feeding increasing amounts of wheat resulted in a decrease in UUN excretion, it also caused a decrease in ruminal pH that possibly compromised DM intake.

The objective of this experiment was to determine the effects of grain type (rolled corn vs. rolled barley) and oil concentration of dried corn distillers grains plus solubles (DDGS; moderate = 7.9% vs. low = 4.5% ether extract) on site of digestion. Seven ruminally and duodenally cannulated Holstein steers (716 ± 8.9 kg) were used in a 4 × 7 Youden square with experimental periods of 24 d. True ruminal organic matter (OM) and crude protein (CP) digestibility (% of intake) as well as intestinal (% of entering duodenum) and total tract starch digestibility was greater (P ≤ 0.03) in steers fed diets containing barley than in steers fed diets containing corn. Ruminal disappearance and ruminal, intestinal, and total tract OM, CP, and starch digestibility were not influenced (P ≥ 0.11) by feeding diets containing DDGS with differing oil concentration. Total tract lipid digestibility (%) was greater (P < 0.001) in steers fed diets containing moderate-oil DDGS than low-oil DDGS. These data indicate that including a low-oil DDGS, as compared with a moderate-oil DDGS, in finishing diets containing rolled corn or rolled barley does not influence intake or site of digestion of nonlipid components.

Abstract A 112 d finishing study was conducted to evaluate the effects of feeding dried distillers grains plus solubles (DDGS) from the MSC-Fiber stream of the FluidQuip post-fermentation fiber separation process compared to conventional DDGS. Yearling crossbred steers (n = 240, initial BW = 463 ± 35kg) were blocked by initial BW, stratified by BW, and assigned randomly to pen (n = 30; 8 steers/pen). Treatments were arranged as a 2×2 + 1 factorial with DDGS type (MSC DDGS [MSC]; Conventional DDGS [CONV]) and inclusion level (20 or 40% diet DM) as the factors. All treatments were compared to a corn-based control (CON). DDGS replaced a 60:40 blend of high-moisture corn and dry-rolled corn. All diets contained 7.5% alfalfa hay and supplement. Data were analyzed as a randomized block design with pen as experimental unit and block as fixed effect. Increasing concentrations of CONV or MSC resulted in a linear increase in DMI (P &lt; 0.01). Steers fed 40% MSC had the greatest DMI (P &lt; 0.01) while CON steers had the least (P &lt; 0.02). Daily gains for MSC steers linearly increased (P = 0.03), while CONV steers showed a tendency for a quadratic response to ADG (P=0.08). Feed efficiency of CONV steers increased quadratically (P = 0.04) and tended to decrease linearly (P = 0.09) for steers fed MSC. Efficiency was greatest for 20% CONV but not different (P &gt; 0.16) than CON, or 20% MSC. Steers fed 40% MSC or 40% CONV were not different in feed efficiency. Inclusion of MSC DDGS resulted in linear increases in DMI and ADG over CON, but decreased feed efficiency by 1.0 and 5.3% resulting in MSC DDGS having a relative feeding value of 95.0 and 86.7% of corn at 20 and 40% DM, respectively.
