The Thai Journal of Veterinary Medicine

Elephant endotheliotropic herpesviruses (EEHVs) can cause fatal hemorrhagic disease in elephants, especially young captive Asian elephants (Elephas maximus). Currently, seven EEHV types have been reported. In this study, EEHVs were examined in whole-blood samples derived from 56 captive Asian elephants from eight provinces in Thailand by nested PCR using primers specific to the viral DNA polymerase gene in an attempt to monitor EEHV elephant cases. After EEHV testing, one sample (1.78%) was positive and found to be closely related to EEHV4 with 99% amino acid identity. This sample was from a three-year-old female Asian elephant with no clinical signs. These …

School of Veterinary and Biomedical Sciences: Faculty Publications

Nonalcoholic steatohepatitis (NASH) patients have elevated plasma saturated free fatty acid levels. These toxic fatty acids can induce liver cell death and our recent results demonstrated that the biliary epithelium may be susceptible to lipotoxicity. Here, we explored the molecular mechanisms of cholangiocyte lipoapoptosis in cell culture and in an animal model of NASH. Treatment of cholangiocytes with palmitate (PA) showed increased caspase 3/7 activity and increased levels of cleaved poly (ADP-ribose) polymerase and cleaved caspase 3, demonstrating cholangiocyte lipoapoptosis. Interestingly, treatment with PA significantly increased the levels of microRNA miR-34a, a pro-apoptotic microRNA known to be elevated in NASH. …

A Blueprint To Evaluate One Health, Simon R. Rüegg, Barry J. Mcmahon, Barbara Häsler, Roberto Esposito, Helen O'Shea, Et Al Feb 2017

A Blueprint To Evaluate One Health, Simon R. Rüegg, Barry J. Mcmahon, Barbara Häsler, Roberto Esposito, Helen O'Shea, Et Al

Department of Biological Sciences Publications

One Health (OH) positions health professionals as agents for change and provides a platform to manage determinants of health that are often not comprehensively captured in medicine or public health alone. However, due to the organization of societies and disciplines, and the sectoral allocation of resources, the development of transdisciplinary approaches requires effort and perseverance. Therefore, there is a need to provide evidence on the added value of OH for governments, researchers, funding bodies, and stakeholders. This paper outlines a conceptual framework of what OH approaches can encompass and the added values they can provide. The framework was developed during …

Detection Of Strongylus Vulgaris In Equine Faecal Samples By Real-Time Pcr And Larval Culture – Method Comparison And Occurrence Assessment, A. Kaspar, K. Pfister, Martin K. Nielsen, C. Silaghi, H. Fink, M. C. Scheuerle

Veterinary Science Faculty Publications

Background: Strongylus vulgaris has become a rare parasite in Germany during the past 50 years due to the practice of frequent prophylactic anthelmintic therapy. To date, the emerging development of resistance in Cyathostominae and Parascaris spp. to numerous equine anthelmintics has changed deworming management and the frequency of anthelmintic usage. In this regard, reliable detection of parasitic infections, especially of the highly pathogenic S. vulgaris is essential. In the current study, two diagnostic methods for the detection of infections with S. vulgaris were compared and information on the occurrence of this parasite in German horses was gained. For this purpose, …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background Taenia solium inflicts substantial neurologic disease and economic losses on rural communities in many developing nations. Ring-strategy is a control intervention that targets treatment of humans and pigs among clusters of households (rings) that surround pigs heavily infected with cysticerci. These pigs are typically identified by examining the animal's tongue for cysts. However, as prevalence decreases in intervened communities, more sensitive methods may be needed to identify these animals and to maintain control pressure. The purpose of this study was to evaluate ultrasonography as an alternative method to detect pigs heavily infected with T. solium cysts. Methodology/Principal Findings We …

Physiological And Behavioural Evaluation Of Common Anaesthesia Practices In The Rainbow Trout, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Lynne U. Sneddon Jan 2017

Physiological And Behavioural Evaluation Of Common Anaesthesia Practices In The Rainbow Trout, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a widely-used model species with relevance to both aquaculture and natural ecosystems. This study sought to establish the relative acute impact of commonly used anaesthetics on rainbow trout when used for anaesthesia or euthanasia by exploring their effects on aversion behaviour and stress physiology. Five widely used anaesthetics were investigated at two concentrations reflective of common laboratory practises: MS-222, benzocaine, 2-phenoxyethanol, …

Israel : Translocation Of Rabies, Sarah Baker Jan 2017

Israel : Translocation Of Rabies, Sarah Baker

Global Public Health

Israel is now faced with a steady growing public health threat as canine rabies has reemerged in the northern region of Israel. While the steady increase in cases is of notable alarm, moreover the close contact most often shared between dog and human populations is of much more concern from a public health prospective. Rabies is a vaccine-preventable disease. Vaccinating dogs has proven to be the most cost-effective strategy for preventing rabies in people. Additionally, education on bite prevention and rabid animal behaviors for both children and adults is an essential extension of the long term rabies vaccination program that …

Relationship Between Dietary Total Digestible Nutrients And Digestible Organic Matter In Beef Cattle Finishing And Growing Diets With Or Without Distillers Grains, Hannah C. Hamilton, Jana L. Gramkow, Jim C. Macdonald Donald, Galen E. Erickson, Andrea K. Watson, Terry J. Klopfenstein Jan 2017

Relationship Between Dietary Total Digestible Nutrients And Digestible Organic Matter In Beef Cattle Finishing And Growing Diets With Or Without Distillers Grains, Hannah C. Hamilton, Jana L. Gramkow, Jim C. Macdonald Donald, Galen E. Erickson, Andrea K. Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The relationship between organic matter digestibility and total digestible nutrients is unestablished for diets containing distillers grains. Three cattle digestion studies were used to evaluate the relationship between total digestible nutrients and digestible organic matter. Results suggest digestible organic matter is consistent relative to total digestible nutrients content for traditional, corn based diets. In finishing and growing diets containing distillers grains additional digestible energy supplied by distillers grains is not accounted for when evaluating only digestible organic matter. Measuring digestible energy content of diets used in digestion trials is essential.

Effect Of Salt Reduction On The Quality And Shelf Life Characteristics Of Deli-Style Roast Beef, Chad G. Bower, Regan E. Stanley, Samodha Fernando Fernando, Gary A. Sullivan Jan 2017

Effect Of Salt Reduction On The Quality And Shelf Life Characteristics Of Deli-Style Roast Beef, Chad G. Bower, Regan E. Stanley, Samodha Fernando Fernando, Gary A. Sullivan

Nebraska Beef Cattle Reports

Concerns with excessive sodium intake have led to increased pressure on meat processors to reduce added salt in meat products. Quality characteristics and microbial growth were evaluated on deli- style roast beef slices formulated to contain varying concentrations of added salt. Salt concentration had no effect on microbial community composition, however increasing salt slowed microbial growth over time. Increasing salt increased cooking yield and decreased water activity. Salt reduction negatively impacts the texture, yield, and shelf life of deli- style roast beef, however salt concentrations within this range do not significantly alter spoilage flora community composition.

Organic Acids And Applications Used For Reduction Of E. Coli On Beef Shoulder Clods Used For Ground Beef, Kelly A. Mccarty, Gary A. Sullivan, Dennis E. Burson Burson Jan 2017

Organic Acids And Applications Used For Reduction Of E. Coli On Beef Shoulder Clods Used For Ground Beef, Kelly A. Mccarty, Gary A. Sullivan, Dennis E. Burson Burson

Nebraska Beef Cattle Reports

Small processors normally grind beef shoulder clods for ground beef that have not been previously tested for shiga toxin-producing E. coli. Three antimicrobial solutions were applied using three application methods to beef sub-primals to evaluate the effectiveness of reducing E. coli and the effects on quality attributes. Antimicrobials effectively reduced Rifampicin resistant E. coli. However, none of the treatments changed color attributes or total plate counts compared to a control. These results suggest that an appropriate antimicrobial solution and application method can be selected for use by small meat processors without affecting quality attributes.

The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Kunze, Nicolas J. Herrera, Katherine I. Domenech-Perez Perez, Michael D. Chao, Chris R. Calkins Jan 2017

The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Kunze, Nicolas J. Herrera, Katherine I. Domenech-Perez Perez, Michael D. Chao, Chris R. Calkins

Nebraska Beef Cattle Reports

Feeding dried distillers grains (DG) may influence calcium flux postmortem by disrupting the stability of the sarcoplasmic reticulum (SR) membrane, thus leading to a higher post- rigor calcium leakage, resulting in greater activation of calpains and improved tenderness. Mitochondria provide the opportunity to study calcium flux in a controlled, tightly defined environment as a model system for the SR. Cattle were finished on diets containing either 0% DG or 50% DG. Feeding DG increased proportions of PUFA in the SR and mitochondrial membrane. Oxidized mitochondria retained less calcium than non- oxidized mitochondria. Mitochondria from cattle finished on corn tended to …

Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacqueline A. Musgrave Musgrave, L. A. Stalker, Mitchell B. Stephenson Jan 2017

Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacqueline A. Musgrave Musgrave, L. A. Stalker, Mitchell B. Stephenson

Nebraska Beef Cattle Reports

Differences in forage quality (crude protein and energy) were analyzed between esophageally fistulated diets, analysis of fecal samples with Nutrition Balance Analyzer (NUTBAL) analysis, and analysis of handclipped forage samples. On upland range sites, hand- clipped samples provided forage quality estimates that were closer to esophageally fistulated diets than samples analyzed with the NUTBAL analysis. Aft er one year of data collection, it appears that there may be some inconstancies with the NUTBAL analysis for estimates on rangeland forage quality in the Nebraska Sandhills. More data is needed to verify these results; however, making management supplementations decisions solely on the …

Summer Cocktail Forage Research In The Panhandle Of Nebraska, Karla H. Jenkins, Cody Creech, Robert Higgins Higgins, Josh Buttle

Nebraska Beef Cattle Reports

Four annual forage mixtures containing brown mid- rib sorghum sudangrass or German foxtail millet, cowpeas or soybeans, and forage collards were compared to the sorghum sudangrass or millet as monocultures in the Nebraska High Plains on dryland acres to determine the tonnage, crude protein, and digestibility available for beef cattle. Th e forage mixtures and the millet resulted in greater crude protein than the sorghum sudangrass. Total digestible nutrients of the mixers were similar. Sorghum sudangrass resulted in the most tonnage. These forage options could have been hayed or windrow grazed in the fall and would have likely resulted in …

Impact Of Inoculum Source For In Vitro And In Situ Digestion Procedures Performed On Corn Residue And Grass Samples, Hannah C. Hamilton, Jana L. Harding, Jim C. Macdonald Donald, Terry J. Klopfenstein Jan 2017

Impact Of Inoculum Source For In Vitro And In Situ Digestion Procedures Performed On Corn Residue And Grass Samples, Hannah C. Hamilton, Jana L. Harding, Jim C. Macdonald Donald, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A study was conducted to assess the effects of inoculum source at time of incubation on neutral detergent fiber digestibility, dry matter digestibility, and organic matter digestibility of corn residue samples. Digestibility of neutral detergent fiber was greater for both grass and corn residue when inoculum source came from steers consuming a high corn residue diet. Digestibility of dry matter and organic matter were not different between grass and corn residue. It is not necessary to maintain two sets of donors for in vitro or in situ procedures involving corn residue. However, donor diet affects neutral detergent fiber digestibility estimates …

Evaluation Of Plant- Waxes To Estimate Forage Intake In Grazing Cattle, Hannah C. Hamilton, Jerry D. Volesky, Robert M. Lewis Lewis Jan 2017

Evaluation Of Plant- Waxes To Estimate Forage Intake In Grazing Cattle, Hannah C. Hamilton, Jerry D. Volesky, Robert M. Lewis Lewis

Nebraska Beef Cattle Reports

Although key to the efficiency of a cattle operation, feed intake is challenging to evaluate in a grazing setting. However, even within forage- based systems, plant- wax markers may be used to predict dietary choices and feed intake. Plant- waxes are a complex mixture of lipids found on the surface of plants. When sufficiently unique among plants, the composition of diets can be determined from the pattern of these compounds in the forages ingested. These markers were used to delineate the parts of the corn plant and, separately, 8 western rangeland grasses and legumes. Using plant waxes, the components of …

Nebraska Beef Cattle Reports

The impact of field peas as a grazing supplement and a component of finishing diets on performance and carcass characteristics was evaluated over two years. During grazing, cattle supplemented with field peas had a greater ending body weight and average daily gain than cattle that received no supplement. However, cattle supplemented with corn had greater average daily gain than both peas and control cattle. Overall, those cattle not supplemented during grazing compensated 53% and 88% when compared to those cattle supplemented corn and peas, respectively. Inclusion of field peas in grower supplement or finishing diets may be advantageous if appropriately …

Effects Of Field Pea Supplementation On Digestibility And Rumen Volatile Fatty Acid Concentration Of Diets Containing High And Low Quality Forages, Hannah L. Greenwell, Jana L. Gramkow, Melissa L. Jolly-Breithaupt Breithaupt, Jim C. Macdonald, Karla Jenkins

Nebraska Beef Cattle Reports

Five ruminally cannulated steers were used to evaluate the effects of supplementation (no supplement, field peas, or dry rolled corn; 0.43% BW) with high and low quality forages on diet digestibility and rumen volatile fatty acid concentrations. Th e inclusion of field peas increased dry matter intake and organic matter digestibility over dry rolled corn and unsupplemented steers. Propionate proportions were less for field peas and control treatments than dry rolled corn, while acetate proportions increased in field peas, and control treatments as compared to dry rolled corn. As a result, acetate to propionate ratio was reduced when dry rolled …

Effects Of Wintering System On Cow And Calf Performance In A Summer- Calving Intensive Production System, Shelby E. Gardine, Jason M. Warner, Curtis J. Bittner Bittner, Robert G. Bondurant, Karla Jenkins, Richard J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein Jan 2017

Effects Of Wintering System On Cow And Calf Performance In A Summer- Calving Intensive Production System, Shelby E. Gardine, Jason M. Warner, Curtis J. Bittner Bittner, Robert G. Bondurant, Karla Jenkins, Richard J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A study evaluated the effects of two wintering systems (cornstalk grazing and drylot feeding) on cow- calf performance in a summer- calving intensively managed cowherd at two locations. Grazing cow- calf pairs on cornstalks resulted in lower ending BW of cows and reduced ADG of calves when compared to drylot cow- calf pairs at weaning. A partial budget of incorporating winter cornstalk grazing into an intensive production system suggests that cows wintered on cornstalks were $136.85 more profitable when compared to cows wintered in the drylot.

Effects Of Modified Distillers Grains And Corn Ratios As Supplements In Diets Varying In Forage Quality On Performance Of Growing Beef Steers, Viviane B. Ferrari, Robert G. Bondurant, Galen E. Erickson Erickson, Terry J. Klopfenstein, Jim C. Macdonald

Nebraska Beef Cattle Reports

Distillers grains (DG) have been intensively used for beef production, but prices relative to corn vary such that it may be beneficial to displace a portion of DG with corn in certain circumstances. Four ratios of supplemental energy (40% of diet DM) from modified distillers grains and corn (100:0, 80:20, 60:40, and 40:60) were supplemented in one of 3 forage diets (56% of diet DM) and evaluated for performance. Forages were high (brome hay + sorghum silage) or low quality. Low quality forages were corn residue baled through conventional rake and bale, or by disengaging the spreader on the combine …
