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.

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 Jan 2014

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.

The Effects Of Diet And Cooler Aging On Consumer Panel Scores For Beef, Kimberly A. Varnold, Chris R. Calkins, Rhonda K. Miller Miller, Galen E. Erickson Jan 2014

The Effects Of Diet And Cooler Aging On Consumer Panel Scores For Beef, Kimberly A. Varnold, Chris R. Calkins, Rhonda K. Miller Miller, Galen E. Erickson

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 …

Grass Type, Grazing Supplementation, And Finishing Diets Affect Beef Fatty Acids, Kimberly A. Varnold, Chris R. Calkins, Brandon L. Nuttelman Nuttelman, Lasika S. Senaratne-Lenagala, Tommi F. Jones, Timothy P. Carr, Galen E. Erickson

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 fatty acid profile, especially in the neutral lipid layer. Warm-season grasses decreased concentrations of most fatty acids compared to cool-season grasses. The provision of WDGS as an energy supplement while grazing dissipated any differences caused by grass type.

Effect Of Distillers Grains Plus Solubles Supplementation On Grazing Cattle Performance, Tyler L. Hasenauer, Terry J. Klopfenstein, James C. Macdonald Donald, Cody J. Schneider, Dirk B. Burken

Nebraska Beef Cattle Reports

Yearlings rotationally grazing smooth bromegrass were individually supplemented modified distillers grains plus solubles (MDGS) at .05, 0.4, 0.6, and 0.8% BW. Gain increased quadratically as MDGS level increased. Maximal ADG (2.95 lb/d) was predicted when supplementing level of 0.48% of BW. Economic analysis compared 0, 2, and 5 lb (DM) MDGS supplementation. When cattle ownership was retained through the feeding period, MDGS supplementation was profitable. Supplementation at 2 lb (DM) was more profitable than 5 lb (DM) when MDGS is above $265.63/ton (DM) or 85% the price of $7.50 /bu corn.

Effects Of Grazing On Nebraska Sandhills Meadow Forage Nutrient Content, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, Karla H. Jenkins, Terry J. Klopfenstein Jan 2014

Effects Of Grazing On Nebraska Sandhills Meadow Forage Nutrient Content, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, Karla H. Jenkins, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Nebraska Sandhills subirrigated meadow pastures were utilized to measure the effects of grazing on forage nutrient content in summer pastures. Pre-grazed pastures had greater protein and in vitro dry matter digestibility levelsand lower neutral detergent fiber levels compared with post-grazed pastures early in the grazing season. By late July, post-grazed vs. pre-grazed pastures did not differ in in vitro dry matter digestibility and neutral detergent fiber levels. Observed results indicate the greatest differences in nutrient content between post-grazed and pre-grazed pastures occur early in the grazing season.

Examination Of The Snsag Surface Antigen Gene Family In Sarcocystis Neurona, Ablesh Gautam

Theses and Dissertations--Veterinary Science

Sarcocystis neurona is a protozoan parasite that causes the serious neurologic disease equine protozoal myeloencephalitis (EPM). The life cycle of S. neurona progresses through multiple developmental stages that differ morphologically and molecularly. The S. neurona merozoite surface is covered by multiple related proteins, which are orthologous to the surface antigen (SAG) gene family of Toxoplasma gondii. The SAG surface antigens in T. gondii and another related parasite Neospora caninum are life cycle stage-specific and seem necessary for parasite transmission and persistence of infection. The present research was conducted to explore the gene family of SnSAGs in S. …

Studies On Equine Placentitis, Igor Frederico Canisso Jan 2014

Studies On Equine Placentitis, Igor Frederico Canisso

Theses and Dissertations--Veterinary Science

Two types of placentitis were studied: ascending and nocardioform placentitis. Although the first diagnosis of nocardioform placentitis was made three decades ago, little is known about the disease, due to the lack of an experimental model. In attempt to develop a research model, Crossiela equi was inoculated through intrauterine, intravenous, intrapharyngeal, and oral routes, but none of the routes resulted in nocardioform placentitis. This may indicate that unidentified factors may play a role in disease pathogenesis and that simple presence of bacteria is not sufficient to induce nocardioform placentitis. The second and major component of this dissertation involved the identification …

Relationships Between Equine Management Practices And Intestinal Parasite Infection, Abigail Pagel Jan 2014

Relationships Between Equine Management Practices And Intestinal Parasite Infection, Abigail Pagel

Honors Projects

Parasitology is an important area of veterinary medicine, but the risk factors for high parasite loads are not well-understood. Equine intestinal parasites can cause extensive disease and death. In the current study, the relationship between equine intestinal parasite loads and adherence to veterinary guidelines for equine management practices was studied. Satisfactory adherence to guidelines regarding food, pasture, and flooding management was related to lower parasite loads. Adherence to guidelines regarding deworming, quarantine, bedding, and water did not appear to lower parasite loads. Still, adhering to these guidelines has been shown to improve equine welfare, even if they are not related …

Comparison Of Long-Term Progestin-Based Synchronization Protocols On Fixed-Time Ai Pregnancy Rate In Beef Heifers, Rebecca A. Vraspir, Adam F. Summers, Doug O'Hare Hare, Larry D. Rowden, Rick N. Funston

Nebraska Beef Cattle Reports

Yearling Angus heifers at a commercial ranch in the Nebraska Sandhills were randomly assigned to one of two progestin-based fixed-time AI protocols (MGA or 14-day CIDR) to compare pregnancy rates. Heifers had similar fixed-time AI pregnancy rates between MGA and 14-day CIDR. A similar proportion of MGA and 14-day CIDR heifers displayed a second estrus; however, heifers previously synchronized with MGA tended to have a greater second AI pregnancy rate. Overall pregnancy rate was similar between MGA and 14-day CIDR treatments. The MGA system was the more cost effective synchronization protocol in this study.

Differences In Fecal Bacterial Community Composition Between Beef Steers Which Are High-Shedders And Low-Shedders Of Shiga Toxin-Producing Escherichia Coli (Stec), Nirosh D. Aluthge, Yoshitha A. Wanniarachchi, Brandon L. Nuttelman Nuttelman, Cody J. Schneider, Terry J. Klopfenstein, Galen E. Erickson, Samodha C. Fernando

Nebraska Beef Cattle Reports

The community composition of the fecal microbiota was compared between beef steers which were high-shedders and low-shedders of Shiga toxin-producing Escherichia coli. Based on Shannon and Chao 1 diversity indices, the high-shedders had a more diverse fecal bacterial community than the low-shedding steers. Members of the genus Prevotella were observed as being more abundant in the low-shedders compared to the high-shedders, while Succinivibrio were more abundant in the high-shedders. Isolation of specific bacteria which are significantly more abundant in low-shedders may pave the way to developing direct-fed microbials which are effective in reducing STEC shedding among high-shedding beef steers.

Optimal Marketing Date Of Steers Depends On Marketing Strategy, James C. Macdonald, Cody J. Schneider, Kelsey M. Rolfe Rolfe, Stephen D. Kachman, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Seven research trials conducted over five years at the University of Nebraska–Lincoln were summarized to determine how animal performance changes through the finishing period on a live and carcass weight basis. Live weight, carcass weight, carcass ADG, and carcass feed efficiency all changed quadratically throughout the feeding period; live ADG and live feed efficiency declined linearly. During times of negative profit margins, optimal profitability for steers marketed on a live-basis occurred by selling early, whereas optimal profitability was achieved by feeding steers marketed on a carcass-basis longer.
