Effect Of Corn Processing In Finishing Diets Containing Wet Distillers Grains On Feedlot Performance And Carcass Characteristics Of Finishing Steers, Kyle J. Vander Pol, Galen E. Erickson, Matthew A. Greenquist, Terry J. Klopfenstein, Thomas Robb
Nebraska Beef Cattle Reports
An experiment evaluated the effects of six corn processing methods in feedlot diets containing 30% (DM basis) wet distillers grains plus solubles (WDGS). Treatments consisted of whole corn, dry-rolled corn, a dry-rolled/ high-moisture corn mix, high-moisture corn, steam flaked corn, and fine ground corn. The ADG was highest for steers receiving dry-rolled corn, high-moisture corn, or a 50:50 blend of dry-rolled and high-moisture corn. Feed conversion was best for steers receiving high-moisture corn. Interestingly, cattle fed finely ground corn or steam-flaked corn did not gain or convert as well as expected. Results indicate that there is a performance advantage obtained …
Effect Of Dietary Inclusion Of Wet Distillers Grains On Feedlot Performance Of Finishing Cattle And Energy Value Relative To Corn, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Thomas Robb
Effect Of Dietary Inclusion Of Wet Distillers Grains On Feedlot Performance Of Finishing Cattle And Energy Value Relative To Corn, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Thomas Robb
Nebraska Beef Cattle Reports
An experiment evaluated the effects of six dietary inclusions of wet distillers grain plus solubles (WDGS) on feedlot performance and carcass characteristics of yearling steers, and also evaluated the energy value of WDGS relative to corn. Treatments consisted of 0, 10, 20, 30, 40, and 50% (DM basis) dietary inclusion of WDGS. Final BW, DMI, and ADG increased quadratically, while feed: gain decreased quadratically as WDGS inclusion increased from 0 to 50% of DM. No differences in carcass characteristics were observed among treatments. Energy value of WDGS relative to corn was above 100% for all inclusion levels and decreased (178 …

Evaluation Of A Low Protein Distillers By-Product For Finishing Cattle, Virgil R. Bremer, Galen E. Erickson, Terry J. Klopfenstein, Kyle J. Vander Pol, Matthew A. Greenquist, Matthew L. Gibson
Nebraska Beef Cattle Reports
An experiment was conducted to evaluate the effect of level of a low protein distillers by-product, Dakota Bran Cake (DBRAN), on feedlot performance and carcass characteristics of yearling steers. Diets contained 0, 15, 30, 45% DBRAN, or 30% dried distillers grains plus solubles (DDGS), replacing corn (DM basis). Final BW, ADG, and F:G improved linearly and daily DMI had a quadratic positive response as level of DBRAN in the diet increased. With the exception of HCW, there were no significant differences for carcass characteristics. The DBRAN had feeding performance similar to DDGS at the same inclusion level. Feeding DBRAN in …

Effect Of Min-Ad Ruminal Buffer And Roughage Level On Ruminal Metabolism And Extent Of Digestion In Steers, Grant I. Crawford, Terry J. Klopfenstein, Galen E. Erickson, Clint Krehbiel, Greg Nunnery
Nebraska Beef Cattle Reports
Six ruminally and duodenally cannulated steers were used in a metabolism experiment to determine effects of adding a ruminal buffer to diets containing increasing levels of roughage. Steers were fed high-concentrate diets containing 4.5, 9.0, or 13.5% alfalfa hay with or without 1.0% MIN-AD ruminal buffer. There were no differences observed in feed intake, ruminal metabolism, or total tract digestibility due to MIN-AD inclusion in the diet. Average pH increased and time below pH 5.6 and pH 5.3 decreased with increasing alfalfa level. Total tract digestibility decreased with increasing alfalfa level. Addition of MIN-AD to high-concentrate diets did not produce …
Sodium Chloride And Soybeans In Feedlot Diets, Sheryl L. Colgan, Terry L. Mader
Sodium Chloride And Soybeans In Feedlot Diets, Sheryl L. Colgan, Terry L. Mader
Nebraska Beef Cattle Reports
Two trials were conducted to evaluate feeding sodium chloride salt (NaCl) and soybeans to feedlot cattle in summer and winter seasons. The treatments were 1) control; 2) 1% added salt; 3) 5% added whole soybeans; and 4) the combination of 1% added salt and 5% added whole soybeans. Added salt had a tendency to decrease dry matter intake and increase water intake. Additional salt and soybeans elevated tympanic temperatures. Treatment did not have an effect on performance, carcass quality grade, or dressing percentage.

Effects Of Field Pea Level And Processing In Finishing Diets, Erin M. Fendrick, Ivan G. Rush, David D. Baltensperger, Dennis R. Brink, Galen E. Erickson
Nebraska Beef Cattle Reports
Cattle were fed coarse rolled or whole field peas in a finishing diet to determine impact on finishing performance. The peas were included in the diet DM at 0%, 15%, and 30%. There were no significant differences in ADG, F:G, or carcass characteristics among processing methods or field pea level. DMI was significantly different due to level and not processing of peas. The DMI increased as the field peas inclusion increased to 30% the diet DM Field peas can be fed whole and replace corn in the diet up to 30%.
Vaccination For Escherichia Coli O157:H7 In Market Ready Feedlot Cattle, Robert Peterson, David R. Smith, Rodney A. Moxley, Terry J. Klopfenstein, Galen E. Erickson, Susan Hinkley
Vaccination For Escherichia Coli O157:H7 In Market Ready Feedlot Cattle, Robert Peterson, David R. Smith, Rodney A. Moxley, Terry J. Klopfenstein, Galen E. Erickson, Susan Hinkley
Nebraska Beef Cattle Reports
A clinical trial was conducted during the summer of 2004 to evaluate the effects of vaccinating cattle against Escherichia coli on the probability of detecting E. coli O157:H7 in feces and colonization at the terminal rectum. The probability for vaccinated or nonvaccinated cattle to shed E. coli O157:H7 in feces was not significantly different. However, the probability for steers to be colonized by E. coli O157:H7 in the terminal rectum was greatly reduced for vaccinated (0.3%) compared with nonvaccinated (20.0%) steers. We concluded that the vaccine was effective at reducing colonization of E. coli O157:H7 at the terminal rectum of …
Large-Scale Clinical Trial To Evaluate An Experimental Escherichia Coli Vaccine, Robert E. Peterson, David R. Smith, Rodney A. Moxley, Terry J. Klopfenstein, Susan Hinkley, Galen E. Erickson
Large-Scale Clinical Trial To Evaluate An Experimental Escherichia Coli Vaccine, Robert E. Peterson, David R. Smith, Rodney A. Moxley, Terry J. Klopfenstein, Susan Hinkley, Galen E. Erickson
Nebraska Beef Cattle Reports
A clinical trial was conducted within 19 Nebraska feedlots to evaluate effects of an E. coli vaccine on the probability to detect E. coli O157:H7 on ROPES or for cattle to be colonized by E. coli O157:H7 at the terminal rectum. Vaccinated pens of cattle were less likely to test ROPE-positive than nonvaccinated pens of cattle and a lower probability for E. coli O157:H7 colonization among vaccinated cattle compared with nonvaccinated cattle was observed. The vaccine was effective at reducing E. coli O157:H7 in the feedlot pen environment and colonization at the terminal rectum of cattle.
Effect Of Optaflexx Dosage And Duration Of Feeding Prior To Slaughter On Feed Conversion And Carcass Characteristics, Grant I. Crawford, Galen E. Erickson, Kyle J. Vander Pol, Matthew A. Greenquist, Jeffrey Folmer, Mike Van Koevering
Effect Of Optaflexx Dosage And Duration Of Feeding Prior To Slaughter On Feed Conversion And Carcass Characteristics, Grant I. Crawford, Galen E. Erickson, Kyle J. Vander Pol, Matthew A. Greenquist, Jeffrey Folmer, Mike Van Koevering
Nebraska Beef Cattle Reports
Finishing steer calves were fed 0, 100, or 200 mg/head/day of Optaflexx for the final 28, 35, or 42 days of the finishing period. Steers were started on Optaflexx treatment at one-week intervals and marketed as a single group. Feeding Optaflexx to feedlot steers increased ADG, improved F:G, and increased carcass weight. Feeding 200 mg/head/day of Optaflexx improved feed conversion by 8.1% without impacting carcass characteristics. Feeding Optaflexx at 200 mg/head/d for 28 to 42 days appears beneficial when compared with feeding diets without Optaflexx.
Nitrogen Mass Balance And Cattle Performance Of Steers Fed Clinoptilolite Zeolite Clay, Dawn M. Sherwood, Galen E. Erickson, Terry J. Klopfenstein
Nitrogen Mass Balance And Cattle Performance Of Steers Fed Clinoptilolite Zeolite Clay, Dawn M. Sherwood, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A winter and a summer nitrogen mass balance experiment were conducted to analyze effects of feeding clinoptilolite zeolite clay to steers. No differences were found in steer ADG, F/G or carcass characteristics. Nitrogen mass balance and volatilization were not affected by a 1.2% addition of clinoptilolite in feedlot diets. These experiments indicate clinoptilolite zeolite clay does not have a large enough cation exchange potential to be effective in reducing N volatilization in open feedlot pens.
Factors Affecting Nitrogen Losses As Measured Using Forced-Air Wind Tunnels And Nitrogen Mass Balance, Dawn M. Sherwood, Galen E. Erickson, Terry J. Klopfenstein, Dennis D. Schulte, Richard R. Stowell
Factors Affecting Nitrogen Losses As Measured Using Forced-Air Wind Tunnels And Nitrogen Mass Balance, Dawn M. Sherwood, Galen E. Erickson, Terry J. Klopfenstein, Dennis D. Schulte, Richard R. Stowell
Nebraska Beef Cattle Reports
Two experiments using wind tunnels were conducted in conjunction with a N mass balance to evaluate the effect of clinoptilolite zeolite clay on ammonia (NH3) losses. Ammonia losses were measured using the wind tunnels during the last six weeks of each feeding period and compared to losses calculated using a N mass balance. Nitrogen loss, pH, surface DM and N contents, and soil and surface temperatures were assessed as possible contributing factors. There were no differences in NH3 volatilization due to dietary treatments. N loss was influenced by date, % DM, surface N and soil temperature. As …
Economics Of Manure Phosphorus Distribution From Beef Feeding Operations, William F. Kissinger, Galen E. Erickson, Richard K. Koelsch, Raymond E. Massey
Economics Of Manure Phosphorus Distribution From Beef Feeding Operations, William F. Kissinger, Galen E. Erickson, Richard K. Koelsch, Raymond E. Massey
Nebraska Beef Cattle Reports
An economic model was developed to evaluate cost and value of manure distribution. A 2,500 head feedlot was used as a case study to calculate excretion amounts from cattle fed diets with a range of phosphorus. Diet P and subsequent costs of distributing that manure were used to analyze the corresponding costs of manure P distribution, in addition to determining the required acres needed to be in compliance with a nutrient management plan (NMP) based on use of manure P by the crops grown. The model illustrated when animals are fed diets of increasing P concentration, total distribution cost increased, …

Valuing Feedyard Management Education, Experience, And Expertise, Rik R. Smith, Darrell R. Mark
Nebraska Beef Cattle Reports
This study uses a mail survey to determine the value Nebraska feedyard operators place on education, experience, and area of expertise in new assistant manager hires. Using conjoint analysis, calculations are made that estimate the marginal value of moving from one level of these attributes to another. Results show that operators preferred higher levels of education and experience. However, relevant experience was preferred over formal education. As an area of expertise, animal health was valued highest by operators of feedyards in all size categories for new assistant managers. Personnel management was valued lowest. Results suggest prospective assistant managers can maximize …
Alternative Enhancement Strategies For Beef Muscles, Donald A. Moss, Chris R. Calkins
Alternative Enhancement Strategies For Beef Muscles, Donald A. Moss, Chris R. Calkins
Nebraska Beef Cattle Reports
USDA Select grade semitendinosus (eye of round) muscles from 12 cattle were used for controls (non-enhanced); salt and phosphate enhanced; water enhanced, or enhanced by addition of 10% of a solution containing 1, 3, or 5% sodium citrate to evaluate the effect of citrate on meat tenderness. Shear force and trained taste panel ratings were not different, (P > 0.05) between controls and citrate-treated muscles. Less than half of the enhancement solution was retained by the muscle. Perhaps the high connective tissue content of the semitendinosus or poor retention of the enhancement solution contributed to these results, which are in conflict …
Flavor Relationships Among Muscles Of The Beef Chuck And Round, Jessica Meisinger, Chris R. Calkins
Flavor Relationships Among Muscles Of The Beef Chuck And Round, Jessica Meisinger, Chris R. Calkins
Nebraska Beef Cattle Reports
Flavor relationships among muscles and causes of liver-like off-flavor of six muscles from each of 30 beef carcasses were evaluated by a trained sensory panel. The infraspinatus (flat iron) was lowest in sour, metallic, and oxidized flavors and highest in fatty flavor. The vastus lateralis (knuckle side) had the most intense off-flavor and was among the highest for sour and oxidized. Heme iron concentration and pH were lowly related to off-flavor. Of 18 muscles from three carcasses, 16 were high in liver-like off-flavor. These data suggest liver-like off-flavor is related to something that impacts the entire animal.
Statistics Used In The Nebraska Beef Report And Their Purpose
Statistics Used In The Nebraska Beef Report And Their Purpose
Nebraska Beef Cattle Reports
The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore, he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of …

Effects Of Supplementing Dried Distillers Grains To Steers Grazing Summer Sandhill Range, Sarah Morris, James C. Macdonald, Terry J. Klopfenstein, Don C. Adams, Rex Davis, James R. Teichert
Nebraska Beef Cattle Reports
Yearling steers continuously grazed summer native Sandhill range, with supplementation of varying levels of dried distillers grains with solubles (DDGS): 0.26, 0.51, 0.77, and 1.03% BW. Forage intakes were predicted using an equation based on TDN. Forage intakes linearly decreased as level of DDGS increased. Average daily gain linearly increased as level of DDGS increased. Steers were finished and slaughtered. No significant differences were found in feedlot performance or carcass data. Economical analyses were conducted and suggest supplementing DDGS is profitable. Increased gain from supplementing yearling steers DDGS while grazing summer range did not affect feedlot performance and can be …

A System For Wintering Beef Heifers Using Dried Distillers Grains, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A two-year experiment compared two systems for wintering pregnant heifers. The standard system used by the ranch served as the control (CON) and the treatment system (TRT) included a dried distillers grains based supplement. Heifers in the TRT system were heavier and had greater body condition score at end of supplementation. Calving difficulty, percentage of live calves weaned and subsequent pregnancy rate were similar between systems. Calves born to heifers in the TRT system were heavier at birth and weaning. The TRT system cost $10.47/heifer less than the CON system and resulted in equivalent or improved heifer and calf growth …
Feeding Melengestrol Acetate To Bulls Prior To And At Puberty Alters Body Weight, And Hormone Concentration, April Tefler, Ryann Mcfee, Rebecca C. Bott, Joseph Schulz, Debra T. Clopton, Jeffrey W. Bergman, Karl V. Moline, Kathy Hanford, Andrea S. Cupp
Feeding Melengestrol Acetate To Bulls Prior To And At Puberty Alters Body Weight, And Hormone Concentration, April Tefler, Ryann Mcfee, Rebecca C. Bott, Joseph Schulz, Debra T. Clopton, Jeffrey W. Bergman, Karl V. Moline, Kathy Hanford, Andrea S. Cupp
Nebraska Beef Cattle Reports
Melengestrol acetate (MGA), which is commonly used in the beef industry to manipulate ovarian activity of females, was fed to bulls at two times during development, prepubertal (5.5 to 7.5 months) and peri-pubertal (6.5 to 9.5 months), to determine effects on testes size, scrotal circumference, body weight, and/or hormone production. We can conclude that feeding bulls MGA during the prepubertal and peri-pubertal time can alter body weight and testosterone production.
Digestibility Of Undegradable Intake Protein Of Feedstuffs, Joshua R. Benton, James C. Macdonald, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams
Digestibility Of Undegradable Intake Protein Of Feedstuffs, Joshua R. Benton, James C. Macdonald, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams
Nebraska Beef Cattle Reports
Digestibility of undegradable intake protein of subirrigated meadows, upland native range, smooth bromegrass, and other feedstuffs used in several growing trials was measured using the mobile nylon bag technique. In general, as the grazing season progressed, undegradable intake protein (UIP) digestibility of grazed forages decreased. Also, UIP digestibility was highly variable among feedstuffs. Compared to the constant 80% digestibility of UIP used by the 1996 Beef NRC, grazed and harvested forages tend to have much lower UIP digestibility values while the supplemental protein sources evaluated tend to have higher UIP digestibility values.

Economic Optimum Use Of Wet Distillers Grains In Feedlots, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Darrell R. Mark
Nebraska Beef Cattle Reports
An economic analysis was conducted using feedlot performance, current feed ingredient prices, trucking, and cost of feeding inputs to determine economics of feeding wet distillers grains plus solubles (WDGS) at five dietary inclusions. The analysis also incorporated positive corn basis into the model. Cattle returns are greatest when incorporated WDGS is fed at 30 to 40% of DM at feedlots located between 0 and 60 miles from the plant. As distance of the feedlot increases from 60 to 100 miles from the plant, optimum inclusion is between 20 and 30% of dietary DM. Either a 5 or 10 cent positive …
Growth Promoting Agents And Season Effects On Blood Metabolite And Body Temperature Measures, Terry L. Mader, Wanda Kreikemeier
Growth Promoting Agents And Season Effects On Blood Metabolite And Body Temperature Measures, Terry L. Mader, Wanda Kreikemeier
Nebraska Beef Cattle Reports
To assess growth promoting agents efficacy among seasons, triiodothyronine, thyroxine, blood metabolites, and tympanic temperature were measured in summer and winter studies. Within each season, pens of heifers were assigned to one of six growth promotant treatments. Season by growth promotant treatment interactions (P < 0.05) indicated that the combination of estrogen and trenbolone acetate increased triiodothyronine in the winter, whereas trenbolone acetate alone decreased both triiodothyronine and thyroxine in the winter. Maximum tympanic temperature was greater (P < 0.01) in the summer than in the winter, while minimum tympanic temperature was lowered (P < 0.01) in the summer. Changes in blood metabolite levels resulting from the use of growth promotants do not appear to substantially influence seasonal changes in body temperature.

Inhibition Of Methanogenesis In Rumen Fluid Cultures, Eric Behlke, Razvan Dumitru, Stephen Ragsdale, James M. Takacs, Jess L. Miner
Nebraska Beef Cattle Reports
We identified 32 compounds that inhibit 13 to 100% of the methane produced by in vitro cultures of rumen fluid and have the potential to inhibit enteric methanogenesis in ruminant animals. The compounds are analogous to a substrate in the methane biosynthesis pathway, and may inhibit methane production yet not affect other organisms in the rumen.
Livestock Risk Protection Insurance Vs. Futures Hedging: Basis Risk Implications, Rik R. Smith, Darrell R. Mark, Allen L. Prosch
Livestock Risk Protection Insurance Vs. Futures Hedging: Basis Risk Implications, Rik R. Smith, Darrell R. Mark, Allen L. Prosch
Nebraska Beef Cattle Reports
This study analyzes the benefit of Livestock Risk Protection (LRP) insurance to cattle producers in reducing basis risk. Nebraska producers insuring fed cattle with LRP realize a basis risk reduction of one-third to one-half compared to futures or options hedging. Nebraska feeder cattle producers using LRP experience only a slight reduction in basis risk. Reduced basis risk results in smaller errors when forecasting basis levels for future time periods. With more accurate basis forecasts, producers can better estimate net hedged selling prices and, consequently, future cash flows.

Nebraska Beef Cattle Reports
A commercial feedlot study determined manure nutrient flow in six feedlots using a corn and by-product based diet with an average P content of 0.39% (DM basis), and a range of 0.34 to 0.48%. Mass balances for N and P were conducted on each pen. The average feed nutrient intake was 0.52 lb N/head/day (64.0 + 7.6 lb/animal fed) and 0.09 lb P/head/day (10.9 + 2.2 lb/animal fed). Based upon averages from the 6,366 head of cattle, 11.5% of the feed nitrogen and 16.9% of the feed phosphorus were retained by the animal with the remaining nutrients excreted. The harvested …
The Influence Of Cooking Rate And Holding Time On Beef Flavor, Jennie M. James, Chris R. Calkins
The Influence Of Cooking Rate And Holding Time On Beef Flavor, Jennie M. James, Chris R. Calkins
Nebraska Beef Cattle Reports
Seven muscles from 10 beef carcasses were cooked quickly or slowly and held 0 or 1 hour to explore the influence of cooking rate and holding time on beef flavor. Off-flavor intensity was lowest when beef was cooked slowly (on a 300°F grill instead of a 480°F grill) and when it was held for 1 hour prior to sensory evaluation. The infraspinatus (flat iron) had the least intense off-flavor and the vastus intermedius (knuckle bottom) had the most intense off-flavor. Slow cooking or holding for 1 hour prior to consumption reduced the intensity of off-flavor in value cuts.
Wet Distillers Grains Plus Solubles Do Not Increase Liver-Like Off-Flavors In Cooked Beef, Blaine Jenschke, Jennie James, Kyle Vander Pol, Chris R. Calkins, Terry J. Klopfenstein
Wet Distillers Grains Plus Solubles Do Not Increase Liver-Like Off-Flavors In Cooked Beef, Blaine Jenschke, Jennie James, Kyle Vander Pol, Chris R. Calkins, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Crossbred steers fed with varying levels of wet distillers grains to test the incidence of liver-like off-flavors. USDA Choice steaks, when compared to USDA Select, had significantly higher trained sensory muscle fiber tenderness scores, less detectable connective tissue, higher juiciness scores, and more intense off-flavor ratings. USDA Choice steaks had a higher percentage of panelists denote liver-like and metallic off-flavors. Wet distillers grains did not significantly influence off-flavor indicating these by-products can be used to finish cattle without causing detrimental effects on the sensory profile.
