The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Wilkerson

Department of Animal Science: Dissertations, Theses, and Student Research

Distillers grains (DG) contribute to cattle sarcoplasmic reticulum (SR) membrane instability by increasing poly-unsaturated fatty acid (PUFA) content in the SR membrane, possibly resulting in early postmortem calcium (Ca) leakage and improved tenderness. Mitochondria are relatively easy to isolate intact and provide the opportunity to study Ca in an SR model. The objective of this research was to determine the influence of diet and oxidation on Ca release from mitochondria. Cattle (n = 48) were fed a corn-based finishing diet with or without deoiled, dried DG (50% DM basis). Steaks from each strip loin were aged for 2, 8, …

Three replications of deli-style ham treatments were manufactured in a 3 x 4 factorial arrangement of salt concentration (0.7%, 1.4%, or 2.1%, meat block basis) and nitrite concentration and source (0 ppm, 100 ppm or 200 ppm sodium nitrite, SN, or 100 ppm sodium nitrite equivalent from pre-converted celery juice powder, CP; Veg Stable 506, Florida Food Products). Salt concentration, water activity, cook yield, and texture profile analysis (TPA) were measured on w 0. Color, pH, residual nitrite, and aerobic and …

Development Of Terminal And Maternal Economic Selection Indices In Beefmaster Cattle, Kathleen Pearl Ochsner

Department of Animal Science: Dissertations, Theses, and Student Research

In the design of economic selection indices, the relative importance of traits in the breeding objective is reflected by their relative economic weighting. The objective of this study was to develop two economic selection indices for Beefmaster cattle: one for a terminal production system and one for a maternal production system. The terminal index was developed assuming bulls are mated to mature cows with all resulting progeny harvested. The maternal index was developed assuming bulls are mated to a combination of heifers and mature cows, with resulting progeny retained as replacements or sold at weaning.

Impact Of Finishing Diets With De-Oiled Distillers Grains Or Antioxidant Containing Supplement On Beef Shelf Life, Katherine I. Domenech-Pérez

Department of Animal Science: Dissertations, Theses, and Student Research

In its entirety this dissertation intended to address the impact of feeding several forms of de-oiled corn distillers grains plus solubles and the effect of supplementing OmniGen-AF as a potential antioxidant source for extending beef shelf life. In study one we learned that despite the de-oiling process, greater inclusion levels (65%, DM basis) of de-oiled wet distillers grains plus solubles (WDGS) causes an increase in polyunsaturated fatty acids (PUFA) similar to the levels obtained with full-fat WDGS. Lower inclusion levels (35 and 50%, DM basis) of de-oiled WDGS have intermediate PUFA content in comparison to 65% de-oiled WDGS, full-fat WDGS …

Genetic Parameters For Docility, Weaning Weight, Yearling Weight And Intramuscular Fat Percentage In Hereford Cattle, José A. Torres-Vazquez

Department of Animal Science: Dissertations, Theses, and Student Research

Temperament in cattle can be described as the reactivity or fear response to human handling, and it is important to beef cattle producers not only from a human safety but also due to potential correlations with other economically traits. Before a docility selection metric can be added to a genetic evaluation, any potential antagonisms with economically relevant traits should be quantified. The objective was to estimate genetic parameters, including genetic correlations, for chute score (CS), weaning weight (WW), yearling weight (YW), and intramuscular fat percentage (IMF) in Hereford cattle. Single-trait and bivariate animal models were used to estimate heritabilities and …

Beef Systems Management Strategies: Calving Date Selection, Estrus Synchronization, And Post-Weaning Management, Benjamin T. Tibbitts

Department of Animal Science: Dissertations, Theses, and Student Research

The objective of an invited review and four experiments was to evaluate production implications and economic efficiencies of beef systems strategies involving calving date selection, utilization of reproductive technology, and post-weaning management of heifers and steers. The invited review in chapter II considers factors that influence a producer’s decision on when to calve beef females. The calving date decision impacts the entire beef production cycle and must take into account any environmental conditions, available resources, and cite specific advantages and/or disadvantages. Understanding the importance of varying physiological state and nutrient demands associated with lactation and gestation is critical to optimizing …

Intrauterine Growth-Restricted Sheep Fetuses Exhibit Smaller Hindlimb Muscle Fibers And Lower Proportions Of Insulin-Sensitive Type I Fibers Near Term, Dustin T. Yates, Caitlin N. Cadaret, Kristin A. Beede, Hannah E. Riley, Antoni R. Macko, Miranda J. Anderson, Leticia E. Camacho, Sean W. Limesand

Department of Animal Science: Faculty Publications

Intrauterine growthrestricted sheep fetuses exhibit smaller hindlimb muscle fibers and lower proportions of insulin-sensitive Type I fibers near term. Am J Physiol Regul Integr Comp Physiol 310: R1020–R1029, 2016. First published April 6, 2016; doi:10.1152/ajpregu.00528.2015.—Intrauterine growth restriction (IUGR) reduces muscle mass and insulin sensitivity in offspring. Insulin sensitivity varies among muscle fiber types, with Type I fibers being most sensitive. Differences in fibertype ratios are associated with insulin resistance in adults, and thus we hypothesized that near-term IUGR sheep fetuses exhibit reduced size and proportions of Type I fibers. Placental insufficiency-induced IUGR fetuses were 54% smaller (P < 0.05) than controls and exhibited hypoxemia and hypoglycemia, which contributed to 6.9- fold greater (P < 0.05) plasma norepinephrine and 53% lower (P < 0.05) plasma insulin concentrations. IUGR semitendinosus muscles contained less (P < 0.05) myosin heavy chain-I protein (MyHC-I) and proportionally fewer (P < 0.05) Type I and Type I/IIa fibers than controls, but MyHC-II protein concentrations, Type II fibers, and Type IIx fibers were not different. IUGR biceps femoris muscles exhibited similar albeit less dramatic differences in fiber type proportions. Type I and IIa fibers are more responsive to adrenergic and insulin regulation than Type IIx and may be more profoundly impaired by the high catecholamines and low insulin in our IUGR fetuses, leading to their proportional reduction. In both muscles, fibers of each type were uniformly smaller (P < 0.05) in IUGR fetuses than controls, which indicates that fiber hypertrophy is not dependent on type but rather on other factors such as myoblast differentiation or protein synthesis. Together, our findings show that IUGR fetal muscles develop smaller fibers and have proportionally fewer Type I fibers, which is indicative of developmental adaptations that may help explain the link between IUGR and adulthood insulin resistance

Adrenal Demedullation And Oxygen Supplementation Independently Increase Glucose-Stimulated Insulin Concentrations In Fetal Sheep With Intrauterine Growth Restriction, Antoni R. Macko, Dustin T. Yates, Xiaochuan Chen, Leslie A. Shelton, Amy C. Kelly, Melissa A. Davis, Leticia E. Camacho, Miranda J. Anderson, Sean W. Limesand

Department of Animal Science: Faculty Publications

In pregnancies complicated by placental insufficiency and intrauterine growth restriction (IUGR), fetal glucose and oxygen concentrations are reduced, whereas plasma norepinephrine and epinephrine concentrations are elevated throughout the final third of gestation. Here we study the effects of chronic hypoxemia and hypercatecholaminemia on β-cell function in fetal sheep with placental insufficiency-induced IUGR that is produced by maternal hyperthermia. IUGR and control fetuses underwent a sham (intact) or bilateral adrenal demedullation (AD) surgical procedure at 0.65 gestation. As expected, AD-IUGR fetuses had lower norepinephrine concentrations than intact-IUGR fetuses despite being hypoxemic and hypoglycemic. Placental insufficiency reduced fetal weights, but the severity …

Feeding Wet Distillers Grains Plus Solubles With And Without A Direct-Fed Microbial To Determine Performance, Carcass Characteristics, And Fecal Shedding Of Escherichia Coli O157:H7 In Feedlot Heifers, B. K. Wilson, B. P. Pulsipher, D. L. Step, M. E. Jacob, D. L. Vanoverbeke, C. J. Richards, T. G. Nagaraja, C. R. Krehbiel

Department of Animal Science: Faculty Publications

The inclusion of wet distillers grains plus solubles (WDGS) in feedlot diets has become a common practice in many regions of the United States due to the expanded production of byproducts and fluctuating corn prices related to ethanol production and other factors. In addition, societal concerns over the continued use of antimicrobials in agriculture production combined with an enhanced interest in disease and pathogen prevention in the food supply have led to an increased interest in use of direct-fed microbials (DFM) in growing and finishing cattle. Direct-fed microbials have been shown to improve ADG and feed efficiency, alter ruminal fermentation, …

Phenome-wide association is a novel reverse genetic strategy to analyze genome-tophenome relations in human clinical cohorts. Here we test this approach using a large murine population segregating for ~5 million sequence variants, and we compare our results to those extracted from a matched analysis of gene variants in a large human cohort. For the mouse cohort, we amassed a deep and broad open-access phenome consisting of ~4,500 metabolic, physiological, pharmacological and behavioural traits, and more than 90 independent expression quantitative trait locus (QTL), transcriptome, proteome, metagenome and metabolome data sets—by far the largest coherent phenome for any experimental cohort (www.genenetwork.org). …

Carcass Gain, Efficiency, And Profitability Of Steers At Extended Days On Feed, Robert G. Bondurant, Jim C. Macdonald, Galen E. Erickson Erickson, Kate Brooks, Rick N. Funston, Kelly Bruns

Nebraska Beef Cattle Reports

Steers were individually fed for 22 and 44 days longer than the industry average marketing point of 0.5” backfat to determine carcass- based gain, efficiency, and deposition changes throughout the feeding period (142, 163, and 184 days on feed). Premiums and discounts for yield grade, quality grade, and overweight carcasses were applied to determine profitability. Feeding steers for 22 and 44 days longer increased carcass weight, quality grade, and yield grade 4 and 5s. Steers fed 44 days longer had increased total revenue and profit per head despite a decrease in live gain and efficiency.

Site And Extent Of Digestion Of Finishing Diets Containing Syngenta Enhanced Feed Corn, Melissa L. Jolly- Breithaupt, Jana L. Harding, Jim C. Macdonald Donald, Galen E. Erickson, Matt K. Luebbe

Nebraska Beef Cattle Reports

Four ruminally and duodenally fistulated steers were utilized to evaluate the effects of Syngenta Enhanced Feed Corn™ containing an alpha amylase enzyme trait (SYT- EFC) compared to the isoline parental control corn without the alpha amylase enzyme trait (Negative Isoline) on site and extent of digestion in finishing diets. Cattle fed SYT- EFC dry rolled corn had numerically greater postruminal starch digestibility, excreted lower fecal starch, and had greater total tract starch digestibility compared to cattle fed Negative Isoline corn. These data would suggest that cattle are able to utilize more starch from corn containing the SYT- EFC trait, which …

Evaluation Of Different Byproduct Combinations Along With Treated Corn Stover On Growing Steer Performance, Kristen M. Ulmer, Curtis J. Bittner, F. Henry Hilscher Hilscher, Galen E. Erickson, James C. Macdonald

Nebraska Beef Cattle Reports

A growing study was conducted to determine the effects of maximizing the energy density of treated corn stover through feed component additions. Calves fed 46% brome hay diet with treated corn stover and varying amounts of solubles or glycerin had greater dry matter intake, but lower average daily gain compared to calves fed modified distillers grains. Calcium oxide treated corn stover treatments also had lower feed to gain and ending body weight than control calves fed distillers grains. Displacing protein as solubles or fat as glycerin in a treated corn stover feed did not provide the same feeding value as …

Effect Of Winter Distillers Grains Supplementation Level On Spayed Heifer Performance, Robert G. Bondurant, Brandon L. Nuttelman, Curtis J. Bittner Bittner, James C. Macdonald, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The effects of winter level of supplementation were evaluated using spayed heifers grazing winter corn residue followed by brome grass and native range grazing periods and finished on a common diet. Distillers grains were supplemented during winter corn residue grazing at 3, 5, and 7 lb per heifer daily. Gain during the winter phase increased while summer phase decreased with increasing level of winter supplementation. Th ere were no differences in feedlot performance for either year across treatments. In year 2, HCW increased from 820 to 848 and 855 lb as heifers were supplemented 3, 5, or 7 lb distillers …

Effect Of Crude Glycerin Concentration On Forage Digestion Parameters In Beef Calves, Robert G. Bondurant, Jana L. Harding, Melissa L. Jolly- Breithaupt Breithaupt, James C. Macdonald, Andrea R. Mccain, Samodha C. Fernando

Nebraska Beef Cattle Reports

Seven ruminally and duodenally cannulated steers were used to evaluate effects of increasing concentrations of crude glycerin on digestion in high forage diets. As glycerin inclusion increased, DM, OM, and NDF intake decreased. Neither DM nor OM digestibility were affected by glycerin inclusion. While dietary NDF digestibility decreased as glycerin increased, glycerin inclusion had no effect on rate or extent of in situ NDF digestibility estimates. As glycerin inclusion increased, propionate and butyrate VFA proportions increased while acetate decreased. Decreases in acetate to propionate ratio with increasing concentrations of crude glycerin may improve F:G in forage- based diets.

Producer Concerns And Perceptions Regarding The Effect Of Methane On Cattle Production And The Environment, Bradley M. Boyd, Amanda Burken, Lisa Franzen- Castle Castle, Karla Jenkins, Richard J. Rasby, Matt K. Luebbe, Rick Stowell, Samodha C. Fernando, Galen E. Erickson

Nebraska Beef Cattle Reports

Knowledge of producer concerns and perceptions on methane production from cattle and its impact on the environment is unknown. Therefore, the objectives of this survey were to determine what producers know about methane production by cattle and to determine if different age groups, regions of Nebraska, and production size/ type affects producer opinions on enteric methane production and climate change. Producers felt that methane production has little impact on animal performance but were not very confident in their knowledge. Most producers received information related to animal agriculture from veterinarians; therefore, veterinarians should continue to be a major target for extension …

Effects Of Feeding Omnigen- Af® On Immune Function, Performance, And Carcass Characteristics During The Feeding Period, Joe O. Buntyn, Sara E. Sieren, Curtis J. Bittner Bittner, Dirk Burken, Galen E. Erickson, Nicole C. Burdick Sanchez, Jeff A. Carroll, Steven J. Jones, Ty B. Schmidt, Keven C. Dehann, Troy J. Wistuba

Nebraska Beef Cattle Reports

OmniGen- AF (Phibro Animal Health, Quincy, IL) was fed to steers to evaluate the effects on the metabolic and immune response during an immune challenge, as well as feedlot performance. Th e inclusion of OmniGen- AF for either the first 28 d or the entire feeding period) did not impact feedlot performance or carcass characteristics. However, within a subset of cattle receiving an immune challenge (the endotoxin lipopolysaacharide; LPS), OmniGen- AF supplementation did alter the metabolic and immune profile of steers. These results suggest that feeding of OmniGen- AF may enhance the metabolic and immune response if cattle are challenged …

Evaluation Of The Relative Contribution Of Protein In Distillers Grains In Finishing Diets On Animal Performance, Zachary E. Carlson, Galen E. Erickson, James C. Macdonald Donald, Matt K. Luebbe

Nebraska Beef Cattle Reports

A finishing study evaluated the relative contributions of protein from wet distillers grains plus solubles (WDGS) on feedlot performance and carcass characteristics. The protein portion of WDGS was mimicked by corn gluten meal (CGM). Increasing WDGS inclusion from 0 to 40% increased final body weight and gain, decreased intakes, and improved feed efficiency. When CGM was fed to equal protein concentration as WDGS, final body weight and gain increased, and feed efficiency improved. Adding solubles to CGM did not improve feed efficiency. Th e feeding value of CGM was similar to distillers grains, suggesting protein has a major role in …

Modifying Different Components Of Distillers Grains And The Impact On Feedlot Performance, Zachary E. Carlson, Curtis J. Bittner, Dirk Burken Burken, Galen E. Erickson, James C. Macdonald

Nebraska Beef Cattle Reports

A finishing study evaluated the effects of altering distillers grains composition on feedlot performance and carcass characteristics. Replacing dried distillers grains with isolated bran, solubles, and protein did not result in performance similar to commodity dried distillers grains. Exchanging bran for non- pelleted treated corn stover increased intake, reduced efficiency, and decreased 12th rib fat. Cattle fed pelleted treated corn stover had decreased intakes, but similar efficiency and gain as non- pelleted treated corn stover. As solubles increased and replaced protein, intakes increased quadratically and 12th rib fat linearly decreased however, all other performance and carcass characteristics were not different.

Effects Of Dietary Antioxidant Supplementation On Cattle Finished With 30% Wet Distillers Grains Plus Solubles On Fatty Acid Profiles And Display Life, Michael D. Chao, Katherine I. Domenech, Hope R. Voegele Voegele, Emery K. Kunze, Chris R. Calkins

Nebraska Beef Cattle Reports

Steers were finished on either 0% wet distillers grains plus solubles or 30% wet distillers grains plus solubles with four antioxidant treatments to evaluate the effects of finishing diets containing wet distillers grains plus solubles, vitamin E and Agrado Plus on beef fatty acid profiles, discoloration and lipid oxidation of retail- displayed beef. Th e inclusion of 30% wet distillers grains plus solubles increased total polyunsaturated fatty acids of beef, but did not promote discoloration or lipid oxidation compared to the 0% wet distillers grains plus solubles diet. In both diets, feeding vitamin E alone or vitamin E+ Agrado Plus …

Effect Of Feeding Distillers Grains And Supplementing With Dietary Antioxidants On Ground Beef Shelf Life And Fatty Acid Profile, Brandy D. Cleveland, Gary Sullivan

Nebraska Beef Cattle Reports

Ground beef from cattle fed corn- based diets with no wet distillers grains, wet distillers grains plus solubles, wet distillers grains + 1000 IU/hd/d vitamin E, wet distillers grains + 150 ppm/hd/d, Ethoxyquin/ TBHQ (Agrado Plus, Novus International, St. Louis, MO), or wet distillers grains + 500 IU/hd/d vitamin E + 150 ppm/hd/d Ethoxyquin/ TBHQ during the finishing phase were compared to analyze lipid oxidation and fatty acid composition. All ground beef lipid oxidation (raw or cooked) increased over time. Raw beef samples from cattle supplemented vitamin E sustained lower TBARS values than corn aft er 2 d of simulated …

Impact Of Feeding Distillers Grains Or Isolated Components In Distillers Grains On Feedlot Performance And Carcass Traits, Brianna B. Conroy, Matt K. Luebbe, Galen E. Erickson Erickson, Jim C. Macdonald, Jacob A. Hansen

Nebraska Beef Cattle Reports

Six treatments were evaluated to determine the contribution of individual components of distillers grains on finishing performance. Diets were formulated to isolate the contribution of solubles, protein, fat, and fiber compared to a diet containing 40% wet distillers grains or a corn- based control. Th ere was a significant improvement in both feedlot and carcass performance in steers fed the 40% wet distillers grains compared to dry- rolled- corn. Numeric differences between fat, fiber, and protein treatments were observed. However, none of the four component diets alone were able to explain the energy value associated with wet distillers grains.
