Nebraska Beef Cattle Reports
A finishing study evaluated the effects of adding 10, 20 or 30% CaO treated cornstalks to diets containing either 20 or 40% (DM basis) modified distillersgrains (MDGS). Steers fed a diet containing 40% MDGS responded quadratically with 10 and 20% (DM basis) treated residue having equal and better F:G than feeding 30% treated stalks. However, cattle fed 20% MDGS did not respond as well to treated cornstalks with 10% treated stalks having the lowest F:G, but poorer than the control diet with 5% stalks and 20% MDGS.

Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass-type was the major contributor in determining the biochemical composition of L. dorsi steaks, with warm-season grasses causing increased concentrations of moisture and zinc and decreased concentrations of magnesium. Aging 28 days instead of 7 days increased pH and caused an increased concentration of carbohydrates, and non-heme and heme iron in B. femoris steaks. Diet, especially grass type, during grazing, can alter the end …

Transitioning Cattle From Ramp® To A Finishing Diet On Feedlot Performance And Feed Intake Variance, Cody J. Schneider, Brandon L. Nuttelman, Dirk B. Burken Burken, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Individually fed cattle were adapted to high grain diets with a traditional grain adaptation program or one of two RAMP® adaptation programs. RAMP programs adapted cattle to a finishing diet gradually over 28 days in four steps or directly without an adaptation. Feed intake variance among d was greater for traditionally adapted cattle compared to either RAMP program, but DMI was not different during the adaptation period. Over the 138-day period, feedlot performance and carcass traits were not affected by adaptation treatment. Cattle fed RAMP for 10 days can be transitioned to a finishing ration containing 47.5% Sweet Bran …
Using Enspira™ To Improve Fiber Digestion, Jana L. Harding, Galen E. Erickson, James C. Macdonald Donald
Using Enspira™ To Improve Fiber Digestion, Jana L. Harding, Galen E. Erickson, James C. Macdonald Donald
Nebraska Beef Cattle Reports
Two experiments evaluated the effectof treating various feedstuffs with an enzyme(Enspira) on digestibility. Twelve feeds commonly fed to beef cattle were treated with four levels of the enzyme(0, 0.25, 0.50, or 0.75 lb of enzyme per ton of DM). Enzyme treatment increased in vitro DMD of high moisture corn (HMC), wet distillers grains plus solubles (WDGS), corn bran, and husks. There was a quadratic increasein gas production for corn leaves, as well as a linear increase in gas production for corn bran treated with increasing levels of Enspira. Treating feeds with the commercial enzyme Enspiraimproved in vitro digestibility of feeds …
Effect Of Feeding De-Oiled Wet Distillers Grains Plus Solubles On Beef Oxidation And Tenderness, Katherine I. Domenech, Kim A. Varnold, Michelle E. Semler, Michael D. Chao, Tommi F. Jones, Galen E. Erickson, Chris R. Calkins

Nebraska Beef Cattle Reports
Cattle fed a de-oiled wet distiller’s grains plus solubles (WDGS) diet were compared to cattle fed corn or traditional (full-fat) WDGS diets to determine effects on discoloration, oxidation, and tenderness of beef aged for seven and 21 days. At seven days of aging, dietary treatment had no effect on discoloration. At 21 days of aging, beef from cattle fed de-oiled WDGS had less oxidation than the corn control and several of the full-fat WDGS treatments. Although tenderness increased with aging and retail display, dietary treatment had no effect on tenderness. These findings suggest that these dietary treatments, followed by a …

Effects Of Feeding Distillers Grains In A Yearling Beef System On Meat Quality, Kelby M. Sudbeck, Kimberly A. Varnold, James C. Macdonald Donald, Chris R. Calkins, Galen E. Erickson
Nebraska Beef Cattle Reports
Distillers grains use while wintering on cornstalks during summer grazing and during the finishing period was evaluated to determine the effects of lifetime exposure to distillers grains on meat characteristics. Finishing diets with distillers grains increased discoloration in steaks following six days of retail display for steaks aged seven days, and after four days of retail display for steaks aged 21 days. Supplementation during summer grazing increased discoloration when cattle were not finished using distillers grains. There were no differences in oxidative rancidity among dietary treatments. Supplementing with distillers grains prior to finishing was not additive in impacting the color …

Nebraska Beef Cattle Reports
Granulosa cell expression of VEGFAisoforms in dominant bovine follicles was evaluated. Collection of granulosa cells via follicle aspiration revealed altered expression of the proangiogenic VEGFA_164 isoform but not the antiangiogenic VEGFA_164B isoform prior to and after the LH surge. Expression of VEGFA_164 declines as both the LH surge and ovulation approaches. In addition, VEGFA_164 and VEGFA_164B expression prior to the LH surge was positively correlated with FSHR and CYP19A1 expression, suggesting that VEGFA expression may be regulated by FSH. These data indicate differential expression of VEGFA isoforms may be an important feature of bovine dominant follicle development.
Effect Of Pubertal Status And Number Of Estrous Cycles Prior To The Breeding Season On Pregnancy Rate In Beef Heifers, Rebecca A. Vraspir, Adam F. Summers, Andrew J. Roberts Roberts, Rick N. Funston
Effect Of Pubertal Status And Number Of Estrous Cycles Prior To The Breeding Season On Pregnancy Rate In Beef Heifers, Rebecca A. Vraspir, Adam F. Summers, Andrew J. Roberts Roberts, Rick N. Funston
Nebraska Beef Cattle Reports
Three experiments were conducted to evaluate whether pubertal status and number of estrous cycles prior to breeding influences pregnancy rate in beef heifers. Pubertal heifers were heavier and older at the start of breeding and had greater AI and overall pregnancy rate than non-pubertal heifers. Second season pregnancy rate was greater for heifers reaching puberty prior to first breeding and for heifers having ≥ 2 estrouscycles prior to breeding compared with non-pubertal heifers. Pregnancy rate was greater for heifers achieving puberty prior to breeding; however, earlier onset of puberty did not significantly improve first pregnancy rates.

Impact Of Supplemental Protein Source On Pregnant Beef Heifers, Adam F. Summers, T. L. Meyer, Michael F. Kirby Kirby, Jim R. Teichert, Rick N. Funston
Nebraska Beef Cattle Reports
Crossbred, AI-pregnant heifers were fed in a Calan Broadbent individual feeding system for 110 days beginning at approximately day 142 of gestation. Heifers were offered ad libitum grass hay and no supplement, hay plus distillers based supplement, or hay plus dried corn gluten based supplement. Supplements were isocaloric, isonitrogenous, and equal in lipid content but differed in rumen undegradable protein. Protein supplementation increased DMI and ADG in pregnant heifers; however, calf birth BW and subsequent pregnancy rates were similar.

Preconception Distillers Grains Supplementation Improves Mature Beef Cow Return To Estrous, Adam F. Summers, Daniel M. Larson, Andrea S. Cupp Cupp
Nebraska Beef Cattle Reports
For three years, cows and first-calf heifers were supplemented two levels of RUP prior to breeding to determine the effect of RUP on reproductive efficiency and performance. Cows resumed estrous after being supplemented 30 days with distillers grains, but pregnancy rate was not different. First-calf heifer performance and reproductive efficiency was similar regardless of protein supplement offered. Protein supplements offered in this study did not impact cow BW, milk production, or progeny performance. More cows supplemented with distillers grains prior to the breeding season resumedluteal activity prior to breeding; however, pregnancy rates were similar.

Feeding Elevated Levels Of Corn Silage And Mdgs In Finishing Diets, Dirk B. Burken, Brandon L. Nuttelman, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
A finishing experiment evaluatedsubstitution of corn silage and modified distillers grains with solubles (MDGS) in place of corn. The treatment arrangementwas a 2 X 2 + 1 factorial with 15 or 45% corn silage and 20 or 40% MDGS plus a control containing 5% cornstalks and 40% MDGS. There were interactions between corn silage and MDGS for carcass adjusted performance. As corn silage inclusion was increased in the diet, F:G increased when fed with 20% MDGS, however there was no difference when fed with 40% MDGS.

Use Of A Pelleted Corn Residue Complete Feed In Receiving Diets, Sarah J. Peterson, Brandon L. Nuttelman, Dirk B. Burken Burken, James C. Macdonald, Matt K. Luebbe, Galen E. Erickson
Nebraska Beef Cattle Reports
The effects of feeding a complete pelleted feed to newly received steer calves (585 ± 4 lb; n = 1318 ) was compared to a control ration consisting of 32% (DM basis) wet or modified distillers grains, 32% alfalfa hay, 32% dry-rolled corn, and 4% supplement. The pelleted complete feed consisted of 35% corn residue and a blend of grain byproducts and minerals. Feeding the complete pelleted feed increased DMI but decreased ADG, thereby reducing feed efficiency. The pelleted feed numerically reduced morbidity. Feeding a complete pellet consisting of corn residue appears to be a viable option for receiving calves …

Effect Of Irrigation Allocation On Perennial Grass Production And Quality, Gary W. Hergert, Karla H. Jenkins, James Margheim Margheim, Alex Pavlista, Rex Nielsen, Murali Darapuneni
Nebraska Beef Cattle Reports
Cool-season grass mixtures and warm-season grass mixtures were evaluated in 2010, 2011, and 2012 under varying irrigation levels to determine dry matter yield, CP, and TDN for beef cattle in the Nebraska Panhandle. As a generalization, when seasonal precipitation was average, irrigation levels over 10 inches resulted in no significant increase in either grass production or quality. Cool-season grasses produced more dry matter yield and maintained greater CP and TDN than warm-season grasses. In all three years, a mixture of wheatgrasses had greater forage yield than an orchardgrass monoculture or a mixture dominated by bromegrasses. In 2010 and 2011, treatments …
Effect Of Natural Antioxidant Concentration On Lipid Oxidation Of Ready-To-Eat Ground Beef Links From Cattle Fed Distillers Grains In Different Phases Of Production, Brandy D. Cleveland, Joe O.

Effect Of Natural Antioxidant Concentration On Lipid Oxidation Of Ready-To-Eat Ground Beef Links From Cattle Fed Distillers Grains In Different Phases Of Production, Brandy D. Cleveland, Joe O. Buntyn, Amy L. Redfield Redfield, James C. Macdonald, Galen E. Erickson, Tommi F. Jones, Ty B. Schmidt, Gary A. Sullivan
Nebraska Beef Cattle Reports
Shelf life of cooked ground beef links with no, low, or high concentrations of a blend of natural plant extract antioxidant were compared to evaluate lipid oxidation over time. When no antioxidants were added, samples stored nine days or beyond were more oxidized than the samples with the addition of an antioxidant. No differences in lipid oxidation were observed between 0.13% and 0.20% antioxidant concentrations during similar days of refrigerated storage days. Therefore, the addition of natural antioxidants were effective at reducing oxidative rancidity, regardless the concentration of antioxidant.

Effect Of Feeding Distillers Grains And Supplementing With Dietary Antioxidants On Ground Beef Color During Retail Display, Brandy D. Cleveland, Chad G. Bower, Amy L. Redfield Redfield, Gary A. Sullivan
Nebraska Beef Cattle Reports
Ground beef patties from cattle fed corn-based diets with no wet distillers grains (control), wet distillers grains (WDGS), WDGS + 1000 IU/head/day vitamin E, WDGS + 150 ppm/head/day, Ethoxyquin/TBHQ (Agrado Plus, Novus International, St. Louis, Mo.), or WDGS + 500 IU/head/day vitamin E + 150 ppm/head/day Ethoxyquin/TBHQ during the finishing phase were compared to analyze color stability during retail display. As display time increased, patties from all dietary treatments had greater discoloration and became darker, less red, and more yellow. Therefore, beef patties discolored during retail display, but the rate and degree of discoloration were unaffected by diet or antioxidant …
Transitioning Cattle From Ramp® To A Finishing Diet On Feed Intake And Ruminal Ph, Cody J. Schneider, Adam L. Shreck, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson
Transitioning Cattle From Ramp® To A Finishing Diet On Feed Intake And Ruminal Ph, Cody J. Schneider, Adam L. Shreck, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
A metabolism trial was conducted where steers were adapted to high grain diets using a traditional approach or one of two RAMP® adaptation programs. RAMP programs adapted cattle to a finishing diet either gradually over 28 days in four steps or switched to a finishing ration without steps. Feed intake and ruminal pH were monitored continuously throughout the trial. Cattle on the 4-STEP treatment spent more time eating compared to other treatments but total feed consumption was similar among treatments. Ruminal pH was greater for cattle on RAMP adaptation programs when compared to traditional grain adaptation. Cattle fed RAMP …
Economics Of Distillers Grains Supplementation In A Forage System With Spayed Heifers, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider, Galen Erickson, J. D. Volesky
Economics Of Distillers Grains Supplementation In A Forage System With Spayed Heifers, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider, Galen Erickson, J. D. Volesky
Nebraska Beef Cattle Reports
In a two-year study, spayed heifer calves were backgrounded on cornstalks with 2 lb or 5 lb wet distillers grains with solubles supplemented daily. During the summer, heifers grazed native range and received no summer supplementation or were supplemented with modified distillers grains with solubles at 0.6% BW daily. Heifers were finished on a common regimen, and an economic scenario was applied to each phase of production and overall. Supplementing more in winter increased profit, but summer supplementation did not impact overall profitability. Numerically, heifers not supplemented during the summer were more profitable than supplemented heifers.
Effect Of Winter Supplementation Level On Yearling System Profit Across Economic Scenarios, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider
Effect Of Winter Supplementation Level On Yearling System Profit Across Economic Scenarios, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider
Nebraska Beef Cattle Reports
Calves backgrounded in a forage–based, yearling system at a greater ADG maintained a performance advantage through finishing. High-level supplemented cattle gained an additional 0.18 lb daily during finishing and produced an additional 81 lb of saleable live weight compared to cattle backgrounded at a low-supplementation level. Across four economic scenarios with varying corn and distillers prices, high-level supplemented cattle returned $55.54 more than cattle fed a low level of supplementation during the winter backgrounding phase. Corn price would have to exceed $11.70/bu for high supplementation level to no longer be profitable.

Energy Value Of De-Oiled Modified Distillers Grains Plus Solubles In A Forage-Based Diet, Meredith L. Bremer, Andrea K. Watson, Dirk B. Burken Burken, James C. Macdonald, Galen E. Erickson
Nebraska Beef Cattle Reports
Sixty individually fed steers were used to determine the effects of feeding de-oiled modified distillers grains plus solubles (MDGS) on steer performance in an 84-day forage-based growing study. De-oiled MDGS did not significantly alter performance when compared to normal MDGS if fed at the same concentration in growing diets. Inclusion of either de-oiled or normal MDGS at 40% of the diet resulted in improved ending BW, DMI, ADG, and F:G as compared to inclusion of 20% MDGS in the diet.

Effects Of Calf Age At Weaning On Cow And Calf Performance And Efficiency In A Drylot/Confinement Production System, Jason M. Warner, Karla H. Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
An ongoing study evaluated the effectsof calf age at weaning on cow and calf performance and reproduction in a confinement production system. Early-weaning improved cow BW at normal weaning. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake was not different between early-weaned cows and calves compared with normal-weaned pairs. Feed requirements and energy utilization were equal between early- and normal-weaned pairs when fed a distillers grains and crop residue based diet.

Effects Of Winter Supplementation On Cow Performance And Post-Weaning Management On Steer And Heifer Progeny In A Late Spring Calving System, John D. Harms, Rick N. Funston, L. Aaron Stalker Stalker, Jacqueline A. Musgrave, Andrew F. Applegarth, Adam F. Summers
Nebraska Beef Cattle Reports
The objective of this experiment was to evaluate the effects of winter supplementation while grazing dormant Sandhills winter range or meadow on cow performance and the effects of post-weaning management on steer and heifer progeny. Winter treatment had no effect on cow BCS or BW at precalving, prebreeding, and weaning. Steers and heifers fed hay gained more BW during winter treatment compared to those grazing meadow, but post-weaning management had no subsequent effects on steer or heifer progeny.

Use Of Treated Corn Residues In Growing Diets, Sarah J. Peterson, Dirk B. Burken, James C. Macdonald Donald, Galen E. Erickson
Nebraska Beef Cattle Reports
A growing study compared the effectsof pelleting corn residue and treating with calcium oxide or calcium hydroxide. All diets contained 60% corn residue, 36% distillers products, and 4% supplement (DM basis). Steers consuming pelleted diets had increased DMI, greater ending BW, but poorer F:G compared to non-pelleted treatments. Diets containing the chemically treated corn stover had increased ADG and lower F:G compared to the non-treated diets. While both pelleting and chemical treatment with CaO increased DMI, and ADG, only the use of CaO improved feed efficiency.

Nebraska Beef Cattle Reports
A total of 336 steers were fed one of seven finishing diets: a corn-based control, 35%, 50%, or 65% inclusion of wet distillers grains plus solubles (WDGS), either traditional (full-fat) or de-oiled. At harvest, 15 low USDA Choice carcasses within each dietary treatment (n = 105) were selected to evaluate the effect of diet on the fatty acid profile of strip loin steaks aged seven days. Feeding WDGS increased the amount of polyunsaturated fatty acids (PUFA) in comparison to a corn based diet. Feeding de-oiled WDGS resulted in less PUFA’s than the full-fat WDGS diets. It seems that the removal …

Effects Of Dietary Change On Viral-Bacterial Interactions In The Rumen Of Cattle, Christopher L. Anderson, Melissa L. Jolly, Adam L. Shreck Shreck, Galen E. Erickson, Terry J. Klopfenstein, Samodha C. Fernando
Nebraska Beef Cattle Reports
This ongoing study investigates the impact of diet and bacteriophage activity on the structuring of rumen microbial community composition and diversity. Fistulated cattle were acclimated to a given diet for 21 days before samples were collected and subsequently enriched for viral particles with tangential flow filtration. Taxonomic identification, abundance, and functional attributes were assigned to both bacterial and viral communities. Principle coordinate analysis of the bacterial communities revealed significant clustering based on diet. While diet drives the structuring of rumen bacterial communities, bacteriophages may maintain high, constant bacterial diversity.

Effect Of Micro-Aid® Supplementation On Nitrogen Losses From Manure, Andrea K. Watson, Galen E. Erickson, Terry J. Klopfenstein Klopfenstein, Mike J. Rincker
Nebraska Beef Cattle Reports
A 2x2 factorial designed experiment was used to study the effects of Micro-Aid and time on OM and N losses from manure, in a simulated feedlot pen setting. Manure was collected from cattle on a common diet, except for the addition of 1 g Micro-Aid /steer daily. Losses of OM were greater at 60 d than 30 d, and greater for control than Micro-Aid. Nitrogen losses at d 30 were similar between treatments but control pans had greater N losses at d 60. Feeding Micro-Aid to cattle may inhibit N volatilization from manure, enhancing the fertilizer value of manure.

Nebraska Beef Cattle Reports
Crossbred steers (n = 64) grazed warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Finishing cattle on WDGS, especially after beingsupplemented with WDGS, caused declinesin flavor desirability scores of L. dorsi steaks. Conversely, grass type was more influential in B. femoris steaks with warm-season grasses generating lower consumer panel scores. Scores were not different from each other when supplementation was provided. It is recommended that producers provide WDGS supplementation and finish on an all-corn diet in order to create the …
