Comparing Different Drying Methods For Distillers Grains And Its Effects On Feedlot Cattle Performance, Brandon L. Nuttelman, William A. Griffin, Galen Erickson Erickson, Terry Klopfenstein

Nebraska Beef Cattle Reports

An experiment was conducted to evaluate the effect of drying distillers grains plus solubles on cattle performance. The control diet contained no distillers grains. The six additional diets contained 35% distillers grains that were 1) wet distillers grains plus solubles (WDGS), 2) dried distillers grains plus solubles (DDGS), 3) dried distillers grains plus wet solubles at time of feeding (DDG + Solubles), 4) dried distillers grains plus solubles plus water (DDGS + H₂O), 5) modified distillers grains with solubles added prior to drier (MDGSPre), and 6) modified distillers grains with solubles added after the drier (MDGSPost). Cattle fed …

Effect Of Feeding More Than 70% Wet Distillers Grains Plus Solubles On Feedlot Cattle Performance, Amy R. Rich, Galen Erickson, Terry Klopfenstein Klopfenstein, Matt K. Luebbe, Joshua R. Benton, William A. Griffin, Darrell Mark

Nebraska Beef Cattle Reports

A finishing trial evaluated effects of feeding greater than 70% wet distillers grains plus solubles (WDGS) on feedlot cattle performance. The WDGS was fed at 40, 70, 77, and 85% of diet dry matter (DM), while roughage levels ranged from 5 to 25% across treatments. Larger ADG and G:F were observed with 40% WDGS and 5% roughage. Higher levels of WDGS were successfully fed with levels of roughage above 8% but the diets were less profitable than the 40% WDGS diet.

Supplementing Modified Wet Distillers Grains With Solubles To Long Yearling Steers Grazing Native Range, Kelsey M. Rolfe, William A. Griffin, Terry Klopfenstein Klopfenstein, Galen Erickson, Dennis Bauer

Nebraska Beef Cattle Reports

Modified wet distillers grains with solubles (MDGS) were supplemented on the ground to yearling steers with access to native range during summer grazing. Supplemented steers had greater ADG than non-supplemented steers, and were heavier entering the feedlot. Supplemented steers also required 24 fewer days in the feedlot to reach a constant end point, compared to non-supplemented steers. Energy calculations suggest 1.0 lb of MDGS replaced 0.65 lb of summer range.

Effects Of Sulfur Concentration In Distillers Grains With Solubles In Finishing Cattle Diets, Jhones O. Sarturi, Galen Erickson, Terry Klopfenstein Klopfenstein, Judson Vasconcelos, Joshua R. Benton, William A. Griffin

Nebraska Beef Cattle Reports

Effect of dietary sulfur on beef cattle fed diets containing wet or dry distillers grains with solubles (DGS) was evaluated. Sulfur concentration in DGS was either 0.82 or 1.16%. Steers (n = 120; IBW = 761 ± 75 lb) were individually fed ad libitum. Intake decreased when wet and dry 1.16% S DGS were fed. Gain decreased as wet DGS that was 1.16% S increased in the diet to 40%. Feeding wet DGS improved F:G, regardless of sulfur content. Fat thickness and HCW decreased as wet and dry 1.16% S DGS increased in the diet. High sulfur DGS reduced DMI …

Effects Of The Synthetic Antioxidants On Shelf Life Of M. Psoas Major And M. Triceps Brachii Muscles From Beef Fed Wet Distillers Grains, Lasika S. Senaratne, Chris Calkins, Judson Vasconcelos Vasconcelos, Amilton S. De Mello, M. A. Andersen, Stephanie A. Furman, Siroj Pokharel

Nebraska Beef Cattle Reports

Feedlot finishing steers (n = 483) were randomly allotted to four dry-rolled corn based diets containing 0 or 30% wet distillers grains with or without the synthetic antioxidants supplementation (ethoxyquin and tertiary butyl hydroquinone in AGRADO®PLUS). This study intended to minimize detrimental effects of feeding wet distillers grains on color and lipidoxidation of beef tenderloin and clod heart muscles during retail display by feeding a synthetic antioxidant mixture. Feeding AGRADO®PLUS significantly reduced meat discoloration and lipid oxidation.

Nebraska Beef Cattle Reports

Crossbred steers (n = 483) were fed dry-rolled corn based finishing dietscontaining 0 or 30% wet distillers grains with the synthetic antioxidants, ethoxyquin and tertiary butyl hydroquinone (AGRADO®PLUS). Synthetic antioxidants reduced lipid and color deterioration of strip steaks at the end of the retail display period under high or atmosphericoxygen packaging conditions.

Digestibility Of Crop Residues After Chemical Treatment And Anaerobic Storage, Adam L. Shreck, Crystal D. Buckner, Galen Erickson Erickson, Terry Klopfenstein, Michael J. Cecava

Nebraska Beef Cattle Reports

Two experiments were conducted to evaluate factors affecting crop residue digestibility. Corn stover, corn cobs, and wheat straw were alkaline treated at low (35%) or high (50%) moisture and then anaerobically stored at 30 °C or 40 °C. Chemical treatment increased in vitro DM digestibility of all residues by 14 to 21 percentage units (35% to 62% improvement). Samples stored at 50% DM and 40oC were most digestible. Cobs were inherently more digestible than straw or corn stalks. Percentage of total improvement in DM digestibility by optimizing DM, ambient temperature, and chemical treatment was: stalks, 43%; wheat straw, 38%;, and …

Influencing Steer Performance Through Maternal Nutrition, Adam F. Summers, Kenneth H. Ramsay, Jim Teichert Teichert, T. L. Meyer, Rick N. Funston

Nebraska Beef Cattle Reports

Cows were fed a 28% CP cube at one of two supplement levels, high (HN) or low (LN), while grazing dormant winter range during late gestation to determine the effects of maternal supplementation level on male progeny performance and carcass characteristics. Steer initial BW did not differ between treatments; however, year 1 steers from cows fed higher supplement levels had greater final BW, HCW, marbling scores, and carcass value compared with steers from cows receiving lower supplement levels. Year 2 HN steers had greater proportions grading USDA quality grade modest or greater when compared to steers from both treatments in …

Marketing Source-Verified Beef To Restaurant Patrons, Kimberly A. Varnold, Chris Calkins, B. Lynn Gordon Gordon, Wendy I. Umberger

Nebraska Beef Cattle Reports

To determine consumer ordering behaviors in high-end restaurants and to see if consumers are interested in the origin of their beef, both an online survey and in-restaurant taste testing were conducted. About two-thirds of the participants in the in-restaurant taste testing ordered the steak with either the state or farm-of-origin description. Compared to a non-source verified steak, taste participants were willing to pay $4.74 more for the steak with the state-of-origin description, and $8.75 more for the steak with the farm-of-origin description. Almost all of the participants acknowledged the best beef comes from the Midwest, specifically naming Nebraska as a …

Replacement Of Grazed Forage With Wdgs And Poor Quality Hay Mixtures, Sandra Villasanti, L. Aaron Stalker, Terry Klopfenstein Klopfenstein, Walter H. Schacht, Jerry D. Volesky

Nebraska Beef Cattle Reports

A grazing study was conducted at the Gudmundsen Sandhills Laboratory, Whitman, Neb., to evaluate the effects of mixtures of wet distillers grains (WDGS) and straw or hay on grazed forage intake. There was no difference in ADG between the control and 70% hay/30% WDGS; however, steers supplemented with 60:40 blends of straw or hay with WDGS had higher ADG than the other two treatments. Range forage intake was decreased by 44% to 54% when steers were supplemented with the mixes. Feeding a mixture of WDGS and low-quality harvested-forage to cattle grazing rangeland may allow increasing stocking rate without decreasing animal …

Performance Of Growing Cattle Fed Corn Silage Or Grazing Corn Residue From Second Generation Insect-Protected (Mon 89034), Parental, Or Reference Corn Hybrids, Barry M. Weber, Brandon L. Nuttelman, William A. Griffin Griffin, Joshua R. Benton, Galen Erickson, Terry Klopfenstein

Nebraska Beef Cattle Reports

Effects of feeding second generation insect-protected transgenic corn (MON 89034) on growing steer performance was evaluated in two experiments. In Experiment 1, a corn silage-based diet was fed to growing steers in pens, and the transgenic test hybrid was compared to a non-transgenic parental hybrid and two commercially available reference hybrids. In Experiment 2, steers grazing corn residue of the transgenic test hybrid were compared to steers grazing a non-transgenic parental hybrid. In both experiments, growing performance was not affected by source of corn silage or residue.

Nutrient Composition Of Spoiled And Non-Spoiled Wet Byproducts Mixed And Stored With Straw, Jennifer R. Yelden, Crystal D. Buckner, Kelsey M. Rolfe Rolfe, Dana I. Christensen, Terry Klopfenstein, Galen Erickson

Nebraska Beef Cattle Reports

Wet corn byproducts were mixed with straw and stored in 55 gallon barrels for 56 days to simulate bunker storage. The spoilage process caused a decrease in fat content and an increase in pH, NDF, ash, and CP. Covering with plastic or distillers solubles reduced the amount of spoilage and the change in nutrient composition.

Utilizing Dried Distillers Grains With Solubles And Phytase To Alleviate Phosphorus Costs In Finishing Swine, Justin W. Bundy, Philip S. Miller, Roman Moreno, Thomas E. Burkey, Erin Hinkle, Huyen Tran

Nebraska Swine Reports

A total of 24 barrows (86.7 lb) were used over a 12-week experiment to evaluate the effects of utilizing dried distillers grains with solubles (DDGS) and phytase as alternatives to inorganic phosphorus (P) sources. Pigs were assigned to 1 of 4 dietary treatments. Treatments consisted of a common corn and soybean-meal fortified diet (CSB), a diet similar to CSB with phytase added in place of dicalcium-phosphate, a corn and soybean-meal diet with 20% DDGS, and a diet with 20% DDGS and phytase added in place of dicalcium-phosphate. Treatment did not affect (P > 0.10) pig performance for any of the growth …

Forty pigs (66.6 lb) were used in a 14-week 4-phase regime study conducted to evaluate the effect of feeding varying concentrations of DDGS to growing-finishing pigs formulated on a standardized ileal digestibility (SID) lysine (lys) basis, DDGS withdrawal at the last feeding phase, and ractopamine (RAC) supplementation 4 weeks prior to harvesting on carcass quality, and color stability and sensory characteristics of longissimus muscle (LM) of finishing pigs. Treatments consisted in 0, 15, or 40% dietary DDGS inclusion supplemented with or without RAC (4.5 ppm) 4 weeks prior harvesting. Final body weight, hot carcass weight, and dressing percentage were not …

Explanation Of Statistics Used In This Report

Nebraska Swine Reports

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effects we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an "equal" group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

At the end of an experiment, the experimenter must decide whether observed treatment differences are due to "real' effects of the treatments or to random differences due to the sample of pigs assigned …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson

Open Access Theses & Dissertations

The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …
