Contagious Ecthyma In A Rocky Mountain Bighorn Sheep From Utah, David J. Wilson, Leslie Mcfarlane Jan 2012

Contagious Ecthyma In A Rocky Mountain Bighorn Sheep From Utah, David J. Wilson, Leslie Mcfarlane

Human–Wildlife Interactions

In December 2008, near Flaming Gorge Reservoir in northeastern Utah, a 2 ½-year-old male Rocky Mountain bighorn sheep (Ovis canadensis canadensis) was reported in poor body condition with bloody lesions covering the muzzle area. The sheep was euthanized, and samples were submitted to the Utah Veterinary Diagnostic Laboratory in Logan, Utah. The gross and microscopic lesions confirmed the diagnosis of contagious ecthyma (CE). This is the first documented report of CE in bighorn sheep from Utah.


Lead From Spent Ammunition: A Source Of Exposure And Poisoning In Bald Eagles, Luis Cruz-Martinez, Patrick T. Redig, John Deen Jan 2012

Lead From Spent Ammunition: A Source Of Exposure And Poisoning In Bald Eagles, Luis Cruz-Martinez, Patrick T. Redig, John Deen

Human–Wildlife Interactions

Ongoing occurrence of elevated levels of lead in bald eagles (Haliaeetus leucocephalus) following the ban on lead shot for waterfowl hunting led us to hypothesize that spent lead from ammunition, which is present in field residues of white-tailed deer (Odocoileus virginianus), represented a source of lead exposure in eagles. We conducted a case-control study using data from 1,277 bald eagles admitted for rehabilitation from January 1996 through December 2009. A multivariate logistic regression model was used to predict the odds of elevated lead levels using admission date in relation to deer hunting season, recovery location in …


Nutrient Transport By Shrimp Hepatopancreas, Tamla A. Simmons Jan 2012

Nutrient Transport By Shrimp Hepatopancreas, Tamla A. Simmons

UNF Graduate Theses and Dissertations

Purified brush border membrane vesicles (BBMV) were isolated to characterize primary cellular transport mechanisms for white shrimp. The ultimate goal is to determine the effective components of a shrimp’s diet, thereby enhancing growth, as well as nutrient content. Juvenile shrimp are dependent on plant material as a food source. Potassium is a key component of plants, thus it may play a role in nutrient transport. In addition, divalent metals have been shown to act as co-transporters in several other organisms, thus they may serve as a transport mechanism for shrimp.

Fresh, live, white or brown shrimp were obtained, and from …

Serum Lysozyme Concentrations In Broilers Treated With Sel-Plex® And Sodium Selenite And Infected With Еimeria Tenella, Vetsislav Koinarski, Lilian K. Sotirov, Stefan Denev Jan 2012

Serum Lysozyme Concentrations In Broilers Treated With Sel-Plex® And Sodium Selenite And Infected With Еimeria Tenella, Vetsislav Koinarski, Lilian K. Sotirov, Stefan Denev

Turkish Journal of Veterinary & Animal Sciences

The aim of the present study was to elucidate the potential role of humoral factors of innate immunity in broilers infected with Eimeria tenella under the influence of inorganic and organic Se cations. It was found that the chickens treated with Sel-Plex® had higher serum lysozyme concentrations compared to those treated with sodium selenite in infected and noninfected groups. The authors consider that Sel-Plex® has a better expressed immunostimulating effect on serum lysozyme concentrations than sodium selenite.


Biotin Affects The Immune Response Of Piglets Inoculated With Porcine Circovirus Type 2, Chen Hong, Zhang Keying, Ding Xuemei, Chen Daiwen Jan 2012

Biotin Affects The Immune Response Of Piglets Inoculated With Porcine Circovirus Type 2, Chen Hong, Zhang Keying, Ding Xuemei, Chen Daiwen

Turkish Journal of Veterinary & Animal Sciences

Weanling crossbred pigs were used in a 5-week trial to evaluate the effects of biotin and porcine circovirus type 2 (PCV2) challenge on serum cytokine concentrations and humoral immunoresponse. Although not significant, there was a trend towards reduced interferon-\gamma concentration in the challenged pigs compared to the controls, especially at 14 and 21 days postinoculation (dpi). Biotin supplementation with 50 or 200 µg/kg biotin improved these levels, with higher doses producing an earlier and stronger response. Although the magnitude of the immune response was small and inconsistent, diet supplementation with 50 or 200 µg/kg biotin appeared to increase serum immunoglobulin …

A total of 375 rainbow trout were distributed into 5 experimental groups with 3 replicates. At the end of the experiment, the fish that were fed diets containing …


Forage Systems For Finishing Steers In South Louisiana, Jose M. Rodriguez Jan 2012

Forage Systems For Finishing Steers In South Louisiana, Jose M. Rodriguez

LSU Master's Theses

Research has found conflicting results on animal performance and carcass traits associated with the use of forage as the primary feed source for finishing cattle. Consumer interest in forage-fed products has grown and little research has been done comparing performance of forage-fed animals and beef finished on different forages. Spring weaned calves (n=54; 257 ± 2.5 kg; 3/8 Gelbvieh, 3/8 Red Angus, and 1/4 Brahman) were used in the evaluation of three forage systems (S1, S2, and S3) on a 100% forage diet in two consecutive years (June 2009 and 2010). Steers were divided into 9 groups based on initial …


The Effect Of Frozen Storage On The Survival Of Probiotic Microorganisms Found In Traditional And Commercial Kefir, Keely Virginia O'Brien Jan 2012

The Effect Of Frozen Storage On The Survival Of Probiotic Microorganisms Found In Traditional And Commercial Kefir, Keely Virginia O'Brien

LSU Master's Theses

Kefir is a fermented milk traditionally made from a unique starter culture, which consists of numerous bacteria and yeast species bound together in an exopolysaccharide matrix produced by certain lactic acid bacteria. Many health benefits are associated with traditionally produced kefir; however, bulging and leaking packaging, caused by secondary yeast fermentation during storage, has limited large scale manufacture traditionally produced kefir. Commercial kefir products have been designed to reduce these effects by using a pure starter culture consisting of a mixture of bacteria and yeast species that give a flavor similar to traditional kefir, but some health benefits may be …


Development Of An Estradiol-Dopamine Anagonist Protocol For Inducing Ovulation In Seasonally Anovulatory Mares, Pamela Boliew Mitcham Jan 2012

Development Of An Estradiol-Dopamine Anagonist Protocol For Inducing Ovulation In Seasonally Anovulatory Mares, Pamela Boliew Mitcham

LSU Doctoral Dissertations

Five experiments were conducted to assess potential improvements in a protocol for inducing ovulation in seasonally anovulatory mares based upon estradiol pretreatment followed by dopamine antagonist injection. The first experiment compared various doses of estradiol cypionate (ECP) and domperidone (in biodegradable microparticles), as well as additions and deletions to the protocol. It was concluded that as little as 75 mg ECP and as little as 1.5 g of domperidone could be used with success, but that both components were required. In the second experiment, timing of the injection (1, 6, or 11 days apart) and ECP dose were assessed. It …

An Assessment Of Moose (Alces Alces Americana) And Moose Management In Connecticut, Andrew M. Labonte Dec 2011

An Assessment Of Moose (Alces Alces Americana) And Moose Management In Connecticut, Andrew M. Labonte

Master's Theses

Eastern moose (Alces alces americana) populations have been increasing in New England over the past decade. Moose populations have the potential to generate human conflict due to their size, speed, nocturnal behavior, and seasonal mobility. As problems associated with increasing moose populations become more common, the need to develop management strategies that are both effective and acceptable to stakeholders becomes increasingly important. The potential for moose to continue to expand in southern New England and the long-term impacts they may have on Connecticut residents, is unclear. The overall purpose of this study was to assess how suitable Connecticut …


Stable Isotope Diet Reconstruction Of Feral Horses (Equus Caballas) On The Sheldon National Wildlife Refuge, Nevada, Usa, Megan Kathleen Nordquist Dec 2011

Stable Isotope Diet Reconstruction Of Feral Horses (Equus Caballas) On The Sheldon National Wildlife Refuge, Nevada, Usa, Megan Kathleen Nordquist

Theses and Dissertations

Feral horse management has become a subject of significant controversy in the United States. This is because of differing opinions and minimal recent empirical data on feral horses. In recent years, numbers of feral horses have increased due to governmental horse removal restrictions (specifically the Wild Horse and Burro act of 1971). With increasing numbers of feral horses on rangelands, land managers are challenged with identifying the appropriate course of action for satisfying groups with differing opinions. The purpose of this study is to characterize diet consumption through the use of stable isotope dietary analysis (δ15N and δ13C). We did …


Geochemical Analysis Of Ancient Activities At Two Plazas In Cobá, Mexico, Eric G. Coronel Dec 2011

Geochemical Analysis Of Ancient Activities At Two Plazas In Cobá, Mexico, Eric G. Coronel

Theses and Dissertations

Two plazas at Cobá, Mexico, may have been the place of market activity during the classic Maya period. The intense decomposition in the warm, moist soils of the Yucatan Peninsula precludes the identification of organic artifacts in archaeological contexts, but phosphorus and trace elements accumulation in soils may provide evidence of marketing activities. The spatial patterns of P and trace element concentrations were used to elucidate the types of ancient Maya activities that took place in those plazas. Phosphorus concentrations are highly correlated (p-value <0.01) with Fe, Mn, and Zn levels in both Plaza B and D. Although the soil geochemistry of Plaza B does not show a marketplace pattern in comparison with previous studies, the elemental concentrations and distributions within Plaza D join other lines of evidence to support the premise that marketplace activities took place at that location. Soil samples were analyzed using DTPA extraction, Mehlich II, Olsen, and Portable X-Ray Fluorescence (PXRF). Experiments were performed to study the suitability of PXRF for field studies. Aspects that were studied include granule size, soil moisture content, protective plastic films that could interfere with the X-Ray signal when placing the samples on top of the analyzer, and a comparison of certified soil standards to the PXRF elemental concentration readings. The results suggest that a field laboratory could be set up to air-dry and sieve soil samples to a minimum mesh size of #10 (> 2 mm).


Returns To The Introduction Of New Sorghum Cultivars Into The Dairy Industry Of El Salvador, Alexis H. Villacís, John H. Sanders Dec 2011

Returns To The Introduction Of New Sorghum Cultivars Into The Dairy Industry Of El Salvador, Alexis H. Villacís, John H. Sanders

INTSORMIL Presentations

The driver of agricultural development is the introduction of new technology. Sensitive sorghums have long been a critical component of hillside Central American agriculture providing a reserve or insurance policy when the principal staple of maize falters. The insensitive sorghums have been more recently introduced since the ‘70s for planting in the valleys in the second season. In the last thirty years the introduction of new insensitive cultivars has accelerated initially for poultry and in the previous two decades for dairy production. This growth has been facilitated by strategic investments in research by CENTA and the Ministry of Agriculture.

What Are The Effects Of Raw Vs. Pasteurized Milk Consumption On Growth Rate And Fertility In A Colony Of Mice?, Kari Sholing, Lindsay Ganong, Amy Olson Dec 2011

What Are The Effects Of Raw Vs. Pasteurized Milk Consumption On Growth Rate And Fertility In A Colony Of Mice?, Kari Sholing, Lindsay Ganong, Amy Olson

Nutrition Student Work

Interest in consuming unprocessed foods has led to assumptions that raw milk has health benefits over pasteurized milk. This study was designed to evaluate the belief that raw milk is nutritionally superior. Eighteen mice were randomly assigned to one of two groups: raw milk or pasteurized milk. Mice were grouped into breeding trios and given a fresh supply of milk every four hours between 7 a.m. and 11 p.m. for 55 days. Milk consumption was tracked at each feeding by measuring the amount of milk that was provided and the amount of milk that was left from the previous feeding. …


Factors Influencing Travel Order As Proxy For Leadership And Trade-Offs In Activity Budgets In Lactating And Nonlactating African Savanna Elephants, Malgorzata Wisniewska Dec 2011

Factors Influencing Travel Order As Proxy For Leadership And Trade-Offs In Activity Budgets In Lactating And Nonlactating African Savanna Elephants, Malgorzata Wisniewska

Masters Theses & Specialist Projects

Nutritional and energetic needs of female mammals depend upon size or reproductive investment and shape individual activity budgets and behavioral patterns. To maximize nutritional and energetic intake females may increase time allocated to foraging or access resources through risk-prone behaviors, represented as aggression or leadership. Conversely, to minimize nutritional and energetic spending females may engage in risk-averse activities such as resting or nonaggressive social interactions. Females with the highest needs should exhibit activities and behaviors that facilitate the greatest nutritional and energetic returns or highest metabolic savings. The propensity for risk-prone behaviors may be greater among older as well as …


Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller Dec 2011

Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller

Dairy Science

This paper aimed to achieve two different objectives. The first objective of this study was to identify and explain the genetic gain achieved in commercial beef cattle operations with the use of genomic predictions versus the use of visual appraisal and EPDs. The second goal of this paper was to develop a method to easily explain genomic predictions and their practical applications on commercial beef operations to a lay audience, specifically to ranchers. In order to accomplish these objectives, I evaluated three of the most common selection methods used by producers today. These included visual appraisal, expected progeny differences (EPDs), …
