Anti-Müllerian Hormone In Stallions And Mares: Physiological Variations, Clinical Applications, And Molecular Aspects, Anthony N.J. Claes Jan 2014

Anti-Müllerian Hormone In Stallions And Mares: Physiological Variations, Clinical Applications, And Molecular Aspects, Anthony N.J. Claes

Theses and Dissertations--Veterinary Science

Anti-Müllerian hormone (AMH) is a homodimeric glycoprotein that is best known for its role in regression of the Müllerian duct in the male fetus. Accumulating evidence indicates that AMH also has an important role during different physiological processes after birth. In contrast to other species, relatively little is known about AMH in the horse. In chapter one, developmental and seasonal changes in serum AMH concentrations in male horses were determined, and the use of AMH for determination of retained cryptorchid testes was established. In chapter two, the interrelationship between plasma AMH concentrations, antral follicle counts (AFC), and age in mares …

Role Of Viral And Host Factors In Influenza Virus Mediated Inhibition Of Interleukin-23, Ashish Tiwari Jan 2014

Role Of Viral And Host Factors In Influenza Virus Mediated Inhibition Of Interleukin-23, Ashish Tiwari

Theses and Dissertations--Veterinary Science

Influenza virus is one of the major respiratory pathogens of humans as well as animals, including equines. There is an increasing evidence that bacterial infections are the most common cause of the death during influenza. In horses also, secondary bacterial pneumonia can lead to death, and surviving horses may take up to six months for the complete recovery resulting in heavy economic loss to the equine industry. Interleukin (IL)-23 mediated innate immune response has been shown to protect the host from various respiratory bacterial infections. However, studies to investigate the role of host and viral factors in the regulation of …

Examination Of The Snsag Surface Antigen Gene Family In Sarcocystis Neurona, Ablesh Gautam Jan 2014

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 …

Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao Jan 2014

Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao

LSU Master's Theses

Lidocaine, an amide local anesthetic agent, is commonly used in mammals, including humans. There is a general assumption that birds are more sensitive to lidocaine than mammals. Relatively low doses of lidocaine have been suggested to cause toxic effects in birds. While this information appears to be anecdotal, it has been perpetuated in the literature. The overall objective of this thesis research was to determine the tolerance and safety of intravenous lidocaine in broiler chickens. To assess the cardiovascular effects of lidocaine, relative changes on heart rate and mean blood pressure were calculated. Clinically significant cardiovascular effects were defined as …

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.

Effect Of Feeding De-Oiled Wet Distillers Grains Plus Solubles On Beef Oxidation And Tenderness, Katherine I. Domenech, Kim A. Varnold, Michelle E. Semler, Michael D. Chao, Tommi F. Jones, Galen E. Erickson, Chris R. Calkins

Nebraska Beef Cattle Reports

Cattle fed a de-oiled wet distiller’s grains plus solubles (WDGS) diet were compared to cattle fed corn or traditional (full-fat) WDGS diets to determine effects on discoloration, oxidation, and tenderness of beef aged for seven and 21 days. At seven days of aging, dietary treatment had no effect on discoloration. At 21 days of aging, beef from cattle fed de-oiled WDGS had less oxidation than the corn control and several of the full-fat WDGS treatments. Although tenderness increased with aging and retail display, dietary treatment had no effect on tenderness. These findings suggest that these dietary treatments, followed by a …

Wanniarachchi, Brandon L. Nuttelman Nuttelman, Cody J. Schneider, Terry J. Klopfenstein, Galen E. Erickson, Samodha C. Fernando Jan 2014

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 Jan 2014

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.

Turkish Journal of Veterinary & Animal Sciences

To determine sequence characteristics and phylogenetic relationships of the nonstructural (NS) gene, the NS genes of 9 avian influenza (AI) viruses were sequenced and compared with other Iranian AI H9N2 viruses available in GenBank. The similarity among the earliest Iranian H9N2 isolate (A/chicken/Iran/ZMT-101/1998) and recent (2007–2011) studied isolates was low (94%). Some of the studied viruses revealed substitutions in RNA-binding and effector domains as well as antigenic regions of the NS protein. Recently studied isolates have a high similarity (97.4%-98.7%) with some Pakistani isolates (like A/chicken/Sawabi/NARC-2434/2006) in the NS gene. In the phylogenetic analysis, recently studied isolates composed a cluster …

Evaluating The Effects Of Chitosan, Plant Oils, And Different Diets On Rumen Metabolism And Protozoan Population In Sheep, Monika Wencelova, Zora Varadyova, Katarina Mihalikova, Svetlana Kisidayova, Dusan Jalc Jan 2014

Evaluating The Effects Of Chitosan, Plant Oils, And Different Diets On Rumen Metabolism And Protozoan Population In Sheep, Monika Wencelova, Zora Varadyova, Katarina Mihalikova, Svetlana Kisidayova, Dusan Jalc

Turkish Journal of Veterinary & Animal Sciences

Chitosan (CH) has been shown to be a promising natural antimicrobial agent. This study examined the effects on rumen metabolism when providing diets containing high forage (HFD), low forage (LFD), and maize silage (MSD) to a 24-h batch culture in which the diets were not supplemented (control) or were supplemented with CH (100 mg/L), sunflower oil (SF, 35.0 g/kg dry matter), rapeseed oil (RP, 35.0 g/kg dry matter), or SF and RF with chitosan combinations (SFCH and RPCH). Dry matter digestibility in the batch culture was influenced by CH and was decreased in HFD compared with the control (P < 0.01). Decreasing total number of protozoa and the number of Entodinium spp. was evident, especially in LFD and MSD, with all additives. RPCH had a predominantly adverse effect on Dasytricha ruminantium in MSD. Interactions of the diets × additives in the majority of rumen ciliate populations were detected. The concentrations of trans-vaccenic acid and conjugated linoleic acid (c9, t11-CLA) were unchanged by chitosan. However, the combination of SF and RF with chitosan (SFCH and RPCH) positively affected fatty acid profiles, which might be related to differences in diets, SF or RP composition, and different microbial activity in the batch cultures.
