Dried Distillers Grains Supplementation Of Calves Grazing Corn Residue, Kristin H. Gustad, Terry J. Klopfenstein, Galen E. Erickson, Kyle J. Vander Pol, James C. Macdonald, Matthew A. Greenquist

Nebraska Beef Cattle Reports

Dried distillers grains (DDGS) were fed to weanling steer calves grazing nonirrigated corn residue to determine daily gain response and residue intake response to increasing levels of DDGS (from 1.5 to 6.5 lb/day in 1 lb increments). The DDGS was fed individually using Calan electronic gates. Daily gain increased from 0.9 (1.5 lb DDGS) to 1.8 (6.5 lb DDGS) lb/day . Forage intake decreased from 11.3 (1.5 lb DDGS) to 8.3 (6.5 lb DDGS) lb/day . Results provide information for selecting a DDGS supplementation level to achieve a target gain.

Effect Of Corn Hybrid And Processing Method On Site And Extent Of Nutrient Digestibility Using The Mobile Bag Technique, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne Fithian

Nebraska Beef Cattle Reports

The influence of corn hybrid and processing method onsite and extent of DM, starch, and protein digestibility was determined using the mobile bag technique. Samples consisted of three hybrids with known digestibility and feeding value processed as either dryrolled corn (DRC) or high-moisture corn (HMC). Ruminal and total tract nutrient digestibilities were greater for HMC compared to DRC. Differences among hybrids existed for all variables measured except ruminal starch digestibility and degradable intake protein. Undegradable intake protein (UIP) digestibility was greater for HMC compared to DRC (77.8 and 73.7%, respectively). However, UIP was lower for HMC than DRC. Differences among …

Influence Of Corn Hybrid And Processing Method On Digestibility And Ruminal Fermentation, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne Fithian

Nebraska Beef Cattle Reports

Three hybrids with different kernel traits and feeding value were selected from a previous study to determine effects of corn hybrid and processing method (high-moisture corn (HMC), or dry-rolled corn DRC)) on nutrient digestibility and ruminal fermentation. DMI, intake rate, and total time spent eating were greater for HMC than DRC. Changes in ruminal pH and pH variance were also greater for HMC compared to DRC. Total-tract nutrient digestibility was influenced by processing method and hybrid. Nutrient digestibilities were greatest for hybrid 1, and greater for HMC compared to DRC. There was a hybrid by processing method interaction for molar …

Influence Of Corn Hybrid On Kernel Traits, Flint W. Harrelson, Galen E. Erickson, Terry J. Klopfenstein, Lenis Alton Nelson, David S. Jackson

Nebraska Beef Cattle Reports

Sixty commercially available corn hybrids were used to identify kernel traits that may be used as an indicator of feeding value to cattle. Three separate tests were conducted and 12 traits were evaluated for each hybrid. Most production traits were negatively correlated or not correlated to physical traits making them less indicative of cattle performance compared to some lab techniques. Based on the dry matter disappearance in the rumen, a harder kernel will be more efficiently digested. An approximately 10% change in dry matter disappearance is shown between the most and least digestible hybrid. Physical kernel traits can be helpful …

Influence Of Corn Hybrid, Kernel Traits, And Dry Rolling Or Steam Flaking On Digestibility, Flint W. Harrelson, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian, Patrick M. Clark, David S. Jackson

Nebraska Beef Cattle Reports

Seventy-two commercially available corn hybrids were used to quantify the existing range in kernel characteristics shown to correlate with improved feeding value to cattle. Twelve hybrids were steam flaked at two different bulk densities. Hybrids were tested for kernel size, hardness, in situ digestibility, and starch use. For dry rolled corn, a 27% difference in dry matter disappearance was found across hybrids. For flaking, a 6% to 29% improvement over dry rolled corn was observed. An 8% to 36% advantage for flaking in starch digestibility was also found. The results of this trial suggest there can be an interaction between …

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

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

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

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

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

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

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

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

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

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

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

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 …

Summary Of Manure Amounts, Characteristics, And Nitrogen Mass Balance For Open Feedlot Pens In Summer Compared To Winter, William F. Kissinger, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Data from 18 experiments (244 pen means) over a 10-year period were summarized in order to make a long term comparison between seasons dealing with nutrient mass balance studies and characteristics and amount of manure from open feedlot pens. The amount of manure DM increased from 10.6 lb to 20.0 lb/head finished/day from summer (May to September) to winter (November to May). Quantities of OM, ash, and N (lb/head finished/day) increased from 2.5 lb OM, 8.1 lb ash, and 0.13 lb N to 4.8 lb OM, 15.2 lb ash, and 0.22 lb N/ head finished/day from summer to winter, respectively. …

Kantian Meadows: A Just Nursing Home Grounded In The Categorical Imperative, Faith Bjalobok

Electronic Theses and Dissertations

This dissertation examines the structures of contemporary nursing homes and argues that the structure is conducive to the objectification (treatment of a human being as a non-person) of nursing home residents. In order to eliminate the potential for objectification, this project employs the Kantian categorical imperative as its theoretical framework. Based on that framework Kantian Meadows is created as an example of a just nursing home.
