Ethanol producers remove lipid from distillers grains (DG) for applications such as biodiesel production. The effects of the lipid removal on ruminal protein degradability and total-tract CP digestibility of DG are not known. Five ruminally and duodenally cannulated Angus-cross steers (BW = 434 ± 15 kg) were used to incubate in situ bags for determination of protein digestibility of low-lipid (5.54%) DG, medium-lipid (8.40%) DG, high-lipid (12.46%) DG, and cottonseed meal. Ingredients were weighed into individual in situ bags and incubated in the ventral sac of the rumen for 16 h. After ruminal incubation and simulated abomasal digestion, bags were …

A 2-yr study evaluated effects of feeding dried distillers grains (DDG) to yearlings grazing native range at greaterthan- recommended stocking rates on BW gain, grazed forage quality, and forage disappearance. Thirty-six paddocks were assigned randomly to 1 of 3 treatments: 1) control, stocked at a moderate stocking rate (1.48 animal unit months/ha in yr 1, 1.06 animal unit months/ha in yr 2) with no DDG; 2) double stocked, in which stocking rate was exactly twice the control with no DDG; and 3) double stocked with 2.27 kg/d (DM) of DDG per animal. Six paddocks per treatment replication were grazed in …
Fertilization And Supplementation Strategies For Steers Grazing Smooth Bromegrass Pastures, Andrea K. Watson
Fertilization And Supplementation Strategies For Steers Grazing Smooth Bromegrass Pastures, Andrea K. Watson
Department of Animal Science: Dissertations, Theses, and Student Research
Since 2004, fertilizer prices have doubled due to increases in energy prices for production and increased demand for N fertilizer due to high grain prices. This leads to questioning the cost effectiveness of increasing forage production with N fertilizer. At the same time, an increase in ethanol production creates an increase in the production of by-products of the ethanol industry, such as distillers grains. Distillers grains have been shown to be an excellent feed for ruminants both as a supplement while grazing and as part of a complete diet in the feedlot. Distillers grains provide protein, fat, and highly digestible …
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 = …
Effect Of Increasing Dietary Concentration Of Dried Distillers Grains Plus Solubles On Phosphorus Balance In Finishing Steers, Clint Benson, Cody Wright, Josh Mccarthick, Robbi Pritchard
Effect Of Increasing Dietary Concentration Of Dried Distillers Grains Plus Solubles On Phosphorus Balance In Finishing Steers, Clint Benson, Cody Wright, Josh Mccarthick, Robbi Pritchard
South Dakota Beef Report, 2006
Eight crossbred steers (initial BW = 972.2 ± 33.5 lb) were used in a replicated Latin square design to determine the effect of increasing dietary concentrations of dried distillers grains plus solubles (DDGS) on phosphorus (P) balance in finishing steers. The control (CON) diet contained 79% dry rolled corn (DRC), 10% cottonseed hulls, 6% soybean meal (SBM), and 5% mineral supplement (total diet P concentration = 0.26%). In each of the remaining three diets, all of the SBM and a portion of the DRC were removed and replaced with DDGS at 12%, 24%, and 36% of the diet (total diet …
Use Of Corn Co-Products In Soybean Hull-Based Feedlot Receiving Diets, Chad J. Mueller, Donald L. Boggs
Use Of Corn Co-Products In Soybean Hull-Based Feedlot Receiving Diets, Chad J. Mueller, Donald L. Boggs
South Dakota Beef Report, 2005
The use of different supplemental protein sources with soybean hulls in receiving cattle diets were evaluated using 200 Angus steer calves. Diets contained either corn and soybean meal (C-SBM), or soybean hulls with soybean meal (H-SBM), dried corn gluten feed (H-DCGF) or dried distillers grains plus solubles (H-DDGS). The replacement of corn (C-SBM) with soybean hulls (H-SBM) stimulated intake within the first 14 d of the receiving period and throughout the entire growing period (52 d). Supplementing soybean hulls with corn origin protein (COP) versus soybean meal did not result in any performance differences throughout the feeding period. Within the …

South Dakota Beef Report, 2005
A two-year study was conducted at the South Dakota State University Southeast Research Farm in Beresford, SD, to determine the effects of feeding supplemental dried distillers grains with solubles (DDGS) on the performance of mid-gestation and non-gestating, non-lactating beef cows. Ninety-six gestating beef cows (initial BW = 1276.4 ± 22.2; initial BCS = 4.7 ± 0.09) and 96 non-gestating, non-lactating beef cows (initial BW = 1214.0 ± 20.8; initial BCS = 5.4 ± 0.10) were used for year 1 and year 2, respectively. Cows were stratified by weight and allocated to one of 15 pens. Pens were then randomly assigned …

South Dakota Beef Report, 2005
Ninety-six crossbred heifers were used in an experiment to evaluate the effect of dried distillers grains plus solubles (DDGS), fed in the last trimester of gestation, on heifer performance and reproduction. Animals were blocked by previous heifer development strategy (Antelope Research Station range developed = ANT 1; Antelope Research Station dry lot developed = ANT 2; Cottonwood research station = CTW), stratified by expected calving date, body weight and body condition score, and randomly allotted to one of twelve pens. Each pen was randomly assigned to one of two treatments (6 pens/treatment; 4 pens per block). Treatments were 1) dried …
