Experimental Evaluation Of Cooling Effectiveness And Water Conservation In A Poultry House Using Flow Blurring® Atomizers, Rafael M. Rodriguez

USF Tampa Graduate Theses and Dissertations

Increases in population as well as economic improvements in developing countries are generating a larger demand for animal protein products. Current animal growth processes inherently, require the use of water in many forms throughout the growth cycle. Water is the most important natural resource on earth to sustain life, and in many developing countries is a scarce resource that must be used wisely. Studies have revealed that poultry growth can take place with less water consumption, when compared with other sources of animal protein (e.g., cattle, pork). In this research, an evaporative Flow Blurring^® cooling system was considered as …

Development Of A Wild Infant Woolly Monkey Social Interactions, Time Allocation And Behavior Of A Wild Lagothrix Lagotricha Poeppigii Infant And Her Mother, Saba Zewdie

Independent Study Project (ISP) Collection

The lowland woolly monkey (Lagothrix lagotricha poeppigii), like all species of woolly monkey, is extremely threatened due to anthropologic activities such as deforestation, petroleum drilling and commercial hunting across their habitat. Due to their low reproductive rate and low reproductive success in captivity, the captive population is decreasing every year as habitat loss increases. In late February of 2017 an infant female was born on the island of Sumak Allpa, a monkey rehabilitation organization and reserve in the western Ecuadorian Amazon. The woolly monkeys are completely independent on the reserve; and as such her birth marks the first …

Effects Of Transitioning From A Free Choice Tall Fescue (Lolium Arundinaceum) Hay Diet In Late Winter To A Free Choice Spring Tall Fescue Pasture Diet On Plasma Fructosamine Concentrations, Body Weight, And Body Condition Scores Of Stock Horse Mares, Paige A. Smith

Masters Theses & Specialist Projects

Approximately half of all reported laminitis cases are the result of “grass founder” (laminitis associated with long-term over consumption of lush, early spring pastures). Elevated body weights (BW), body condition scores (BCS), and blood glucose concentrations have all been associated with the onset of grass founder. Plasma fructosamine concentrations (PFC) have recently been used as an indicator of long-term (14–21 d), mean blood glucose concentrations in horses and numerous authors have reported that elevated PFC were observed in laminitic horses (Murphy et al., 1997; Keen et al., 2004; Knowles et al., 2012). This study was conducted to evaluate the long-term …

Consumer Sensory Evaluation And Chemical Composition Of Beef Gluteus Medius And Triceps Brachii Steaks From Cattle Finished On Forage Or Concentrate Diets, A. Chail, Jerrad F. Legako, L. R. Pitcher, Robert E. Ward, Silvana Martini, Jennifer W. Macadam

Animal, Dairy, and Veterinary Science Faculty Publications

The objective of this study was to assess the impact of cattle finishing diet and muscle type on meat quality. Consumer sensory response, proximate composition, Warner–Bratzler shear force (WBSF), fatty acid composition, and volatile compounds were assessed from the gluteus medius (GM) and triceps brachii (TB) muscles of cattle (n = 6 per diet) which were grain-finished (USUGrain) on conventional feedlot or 2 forage diets, a perennial legume, birdsfoot trefoil-fin-ished (USUBFT; Lotus corniculatus), and grass-finished (USUGrass; Bromus riparius). Diet had an interacting effect with muscle for all sensory attributes (P ≤ 0.002), except aroma and flavor (P ≥ 0.078). In …

Disappearance And Appearance Of An Indigestible Marker In Feces From Growing Pigs As Affected By Previous- And Current-Diet Composition, Brandy M. Jacobs, John F. Patience, Merlin D. Lindemann, Kenneth J. Stalder, Brian J. Kerr

Animal and Food Sciences Faculty Publications

Background: Indigestible markers are commonly utilized in digestion studies, but the complete disappearance or maximum appearance of a marker in feces can be affected by diet composition, feed intake, or an animal’s BW. The objectives of this study were to determine the impact of previous (Phase 1, P1) and current- (Phase 2, P2) diet composition on marker disappearance (Cr) and appearance (Ti) in pigs fed 3 diets differing in NDF content.

Results: When pigs were maintained on the 25.1, 72.5, and 125.0 g/kg NDF diets, it took 5.1, 4.1, and 2.5 d, respectively, for Cr levels to decrease below the …

Management Strategy Evaluation For The Atlantic Surfclam (Spisula Solidissima) Using A Spatially Explicit, Vessel-Based Fisheries Model, Kelsey M. Kuykendall, Eric N. Powell, John M. Klink, Paula T. Moreno, Robert T. Leaf

CCPO Publications

The commercially valuable Atlantic surfclam (Spisula solidissima) is harvested along the northeastern continental shelf of the United States. Its range has contracted and shifted north, driven by warmer bottom water temperatures. Declining landings per unit of effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. A management strategy evaluation (MSE) for the Atlantic surfclam is implemented to evaluate rotating closures to enhance Atlantic surfclam productivity and increase fishery viability in the MAB. Active agents of the MSE model are individual fishing vessels with …

Population Dynamics Of The Cotton Rat In Southeastern Virginia, Robert K. Rose, Heather Green Salamone

Virginia Journal of Science

We used monthly live trapping for 2.5 years to evaluate the life-history features of the most common small mammal, Sigmodon hispidus (hispid cotton rat), in an old field at its northern limit of distribution on the Atlantic Coast. Peak densities, achieved in late autumn or early winter, were among the highest recorded for the species and were more typical of geographically marginal populations rather than of central ones. Unlike some other marginal populations, hispid cotton rats in southeastern Virginia did not lose significant body mass over the winter (when few juveniles were present) and survival in winter was not significantly …

Extension Education Symposium: Getting The Most Out Of Your Extension Appointment And Still Having A Life, W. Powers, Noelle E. Cockett, Gregory P. Lardy

Animal, Dairy, and Veterinary Science Faculty Publications

Managing the demands of an academic appointment in extension can be a challenging task. Demands from constituent groups, expectations of supervisors, and rigors of promotion and tenure processes can create pressures that young faculty did not expect. Throw in spousal and family duties and you have created a situation that many will find hard to navigate. However, there are ways to cope and, even better news, there are ways to excel in meeting the demands of an academic appointment and enjoying life. Because many new extension faculty members do not have prior experience in extension, best practices in documenting programs …

Exogenous Lactobacilli Mitigate Microbial Changes Associated With Grain Fermentation (Corn, Oats, And Wheat) By Equine Fecal Microflora Ex Vivo, Brittany E. Harlow, Laurie M. Lawrence, Patricia A. Harris, Glen E. Aiken, Michael D. Flythe

Animal and Food Sciences Faculty Publications

Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species. This study was conducted to determine the effect of exogenous lactobacilli on pH and the growth of amylolytic and lactate-utilizing bacteria. Feces were collected from 3 mature geldings fed grass hay with access to pasture. Fecal microbes were harvested by differential centrifugation, washed, and re-suspended in anaerobic media containing ground corn, wheat, or oats at 1.6% (w/v) starch and one of five …

Inhibition Of Listeria Monocytogenes On Ready-To-Eat Meats Using Bacteriocin Mixtures Based On Mode-Of-Action, Paul Priyesh Vijayakumar, Peter M. Muriana

Animal and Food Sciences Faculty Publications

Bacteriocin-producing (Bac⁺) lactic acid bacteria (LAB) comprising selected strains of Lactobacillus curvatus, Lactococcus lactis, Pediococcus acidilactici, and Enterococcus faecium and thailandicus were examined for inhibition of Listeria monocytogenes during hotdog challenge studies. The Bac⁺ strains, or their cell-free supernatants (CFS), were grouped according to mode-of-action (MOA) as determined from prior studies. Making a mixture of as many MOAs as possible is a practical way to obtain a potent natural antimicrobial mixture to address L. monocytogenes contamination of RTE meat products (i.e., hotdogs). The heat resistance of the bacteriocins allowed the use of pasteurization to …

Effect Of Wet Brewer's Grain Inclusion On The Growth Performance, Carcass Performance, And Meat Quality Of Finishing Cattle, Riley T. Parmenter

Theses and Dissertations

The objective of this study was to determine the effects of Wet Brewer’s Grains (WBG) on the growth performance, carcass performance, and meat quality of finishing cattle. Twenty-four (n=24; 12 heifers – 303kg, 12 steers – 346kg) calves of Simmental-Angus genetics were utilized. Calves were paired by sex, blocked by BW within sex in a 2 x 2 factorial arrangement with three replications per treatment, and fed for 140d. Control diets were a conventional corn silage – shelled corn finishing-diet. Experimental diets modeled the control diet with the inclusion of WBG on a thirty-percent DM basis. Cattle were visually appraised …

Estimating Seasonal Variation In Condition Of Yellow Perch, Emily Anne Powers

Biology Graduate Theses

Research has shown that Yellow Perch Perca flavescens, found throughout lakes and streams of North America, are good indicators of environmental health. Due to the correlation between fish condition and ecosystem health it is essential to reliably estimate condition to better manage our fisheries. Therefore, the study objectives were to measure the seasonal changes in adult Yellow Perch percent dry weight (PDW), and compare the reliability of bioelectrical impedance analysis (BIA) and morphometric-based estimates of condition. The seasonal fluctuations in average monthly PDW were measured over a two- year period and were sinusoidal in shape with peaks in August 2015 …

The Role Of Stress Factors In Skeletal Muscle Development, Growth, And Metabolism; Impacts Of Temporally Spaced Repetition On Long-Term Information Retention In An Anatomy And Physiology Course, Caitlin N. Cadaret

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

We sought to identify the effect of sustained maternal inflammation at mid-gestation on fetal mortality, skeletal muscle growth, and development at term. Fetal rats had reduced total mass that coincided with impaired myoblast function, as myoD was reduced and myogenin expression was increased in hindlimb muscle. Fetuses also had increased circulating TNFα at term after maternal inflammation, which decreased TNFR and IL6R mRNA in muscle, reducing sensitivity to cytokines. These findings indicate that sustained maternal inflammation at mid-gestation impairs fetal skeletal muscle growth near-term due to changes in myoblast responsiveness to inflammatory regulation.

To evaluate the acute impact of inflammatory …

Beavers, Jimmy D. Taylor, Greg K. Yarrow, James E. Miller

Wildlife Damage Management Technical Series

The American beaver (Castor canadensis) (Figure 1) is known as an “ecosystem engineer” because of the benefits their dams provide to biological diversity and ecosystem function. It also is considered a “keystone species” because of its ability to transform its environment, creating new habitats upon which other species depend. Despite the many positive benefits beavers provide through foraging and dam building, beavers also create conflict with people when their activities cause damage. The authors of this publication acknowledge and appreciate the many positive benefits that beavers provide; however, the focus of this publication is to provide basic information on beaver …

The Effects Of Xylanase Or An Algal Sourced Zinc Polysaccharide Complex On The Performance Of Laying Hens Fed A Corn And Soybean Diet, Ashley Bigge

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

Two studies were conducted to determine the effects of two different feed additives on the performance of laying hens. Study 1 examined the effects of non-starch polysaccharide degrading enzyme inclusion in a low energy diet. Study 2 examined the effects of supplementing a paramylon zinc polysaccharide complex at increasing concentrations. Both studies utilized a randomized complete block design for treatment assignment, and data were analyzed using the Glimmix procedure in SAS 9.4 for windows.

The first study took place July 2014 to March 2015 and consisted of two phases. Each phase tested a positive control, negative control with lower ME …

Plasma Metabolites Reveal Changes In Physiological State Of Eared Grebes (Podiceps Nigricollis) During Three Non-Migratory Periods, Allison A. Yoshida

Theses

Energy storage and use during the annual cycle of migratory birds is dynamic especially during migration. However, considerable amounts of the annual cycle are spent not migrating, and the physiological state of birds during these non-migratory periods is not well understood. We compared plasma metabolites (TRIG, BUTY, URIC, GLY) in Eared Grebes (Podiceps nigricollis) residing at three important areas when they are not migrating: fall staging (postbreeding at Mono Lake, California), spring staging (pre-breeding at Great Salt Lake, Utah), and an extended stopover prior to spring staging (Salton Sea, California). Plasma metabolites were also measured in resting and active grebes …

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 …

The Effects Of Camelina Sativa Meal On Haemonchus Contortus In Breeding Age Ewes, Nicole Julia Nichols

Student Theses and Dissertations

Gastrointestinal parasites (GIP) are one of the greatest threats to sheep production in the United States. Increased resistance to traditional anthelmintics has created the need for alternative methods to control GIP. The objective of this study was to determine if Camelina sativa (CS) meal could be fed as part of a daily ration to reduce infection rates of the GIP Haemonchus contortus during two 28-day trials. Forty-eight ewes were sorted and fed a 14% crude protein (CP) supplement with or without 10% CS as part of their daily ration. All ewes grazed a mixture of Bermuda (Cynodon dactylon) and tall …

Biology Faculty Publications

A 60-day feeding trial was conducted to assess the effects of processed meal from knife fish Chitala ornata (KFM) as fishmeal replacement in diets of Nile tilapia Oreochromis niloticus juveniles. Five iso-nitrogenous (36.4% in dry matter) and isolipidic diets (8.6% in dry matter) with 0 (D1), 25 (D2), 50 (D3), 75 (D4) and 100% (D5) KFM inclusions were prepared. With a stocking density of 15 fish (0.59 ± 0.01 g) per tank, tilapia juveniles were distributed randomly in fifteen 30-L tanks. Results indicate a significant increase (P < 0.05) in the percent average weight gain, specific growth rate, and feed …

Responses Of King Penguin Aptenodytes Patagonicus Adults And Chicks To Two Food-Related Odours, Gregory B. Cunningham, Sarah Leclaire, Camille Toscani, Francesco Bonadonna

Biology Faculty/Staff Publications

Increasing evidence suggests that penguins are sensitive to dimethyl sulphide (DMS), a scented airborne compound that a variety of marine animals use to find productive areas of the ocean where prey is likely to be found. Here we present data showing that king penguins Aptenodytes patagonicus are also sensitive to DMS. We deployed DMS on a lake near a king penguin colony at Ratmanoff beach in the Kerguelen archipelago. We also presented DMS to ‘sleeping’ adults on the beach. On the lake, penguins responded to the DMS deployments by swimming more, while on the beach, penguins twitched their heads and …

How To Maximize Energy Content In Forage Grasses, S. Ray Smith, Kelly Prince

Forage Symposium at the Kentucky Cattlemen’s Convention

In a recent paper, Kathryn Watts and Jerry Chatterton (2004) gave an excellent overview of the basic factors affecting carbohydrate levels in forages and how these factors affect forage management.

• Sugars are the substrates for all plant growth, thus, they are critical to plant growth and development.
• Sugars are produced by photosynthesis during daylight.
• At night plants use energy from sugars formed by photosynthesis to grow.
• Whenever the rates of photosynthesis exceed plant growth rates, carbohydrates accumulate.
• At times, plant stresses decrease growth rates more than photosynthesis and carbohydrates accumulate.
• Factors that contribute to plant stress include water and nutrient …

Building A Year Round Grazing System, Christopher D. Teutsch

Forage Symposium at the Kentucky Cattlemen’s Convention

There are three basic ways to increase net returns in ruminant livestock operations. The first is to increase the price we get for our product. Unfortunately in a commodity based system we have little or no control over the price that we receive. The second is to increase total production. By producing more units that have a slim profit margin we can increase net returns. However, at some point we become resource limited; we run out of land or time. The third is to control production costs. Of these three ways to increase net returns, this one has the greatest …

Promote Growth And Animal Health With Isoflavones In Red Clover And Other Legumes, Michael D. Flythe, Glen E. Aiken

Forage Symposium at the Kentucky Cattlemen’s Convention

The field of nutrition has continued to expand since the 18th century. We once thought that the only important components in foods and feeds were proteins, carbohydrates, fats and salts. Evidence was slowly pieced together to show that certain minor components were essential for life, and the vitamins were discovered. Like the doctors that first suspected vitamins were essential, some cattlemen have long noted advantages in animal performance and health on certain diets in ways that cannot be explained by a simple forage analysis. Today, we are learning the roles that phenolic plant secondary metabolites, sometimes called polyphenols, play in …

Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker

Theses, Dissertations and Capstones

The brook trout (Salvelinus fontinalis) is facing many challenges throughout the Appalachian region, which are thought to be brought on by effects of climate change and the loss of habitat because of the disturbance from the pursuit of energy sources, namely, the mining of coal in the region. Most of the mining occurs in the central plateau and southern mountain region of West Virginia. The brook trout have historically had an expansive range covering this region and has the potential to inhabit the headwater stream systems that occur very prevalently throughout the Appalachians. In the state of West Virginia, the …

Distribution, Diversity, And Den Locations Of Canidae And Hyaenidae Species Across Habitat Type At Enashiva Nature Refuge, Grace Bullington

Independent Study Project (ISP) Collection

Due to the importance of top-trophic level predators have on their environment including regulating prey species and influencing ecosystem biodiversity, it is important to monitor top-trophic level predators to understand how they shape their ecosystem. While top-trophic level predators can benefit the ecosystem, they can also cause problems for surrounding human settlements like predation on livestock. Species in the Canidae and Hyaenidae families occupy the top-trophic level and can influence their ecosystem and cause human-wildlife conflict.

This study looked at the distribution, diversity, and den locations of Canidae and Hyaenidae species at Enashiva Nature Refuge over the course of 21 …

The City Where The Storks Fly: Sustainable Agriculture And Species Reintroduction In Toyooka City, Japan, Nako Kobayashi

Anthropology Department Honors Papers

In 1971, the Oriental White Stork went locally extinct in Toyooka, Japan. Today, around 80 of the birds fly free throughout the city. Toyooka uses the Stork Reintroduction Project and the promotion of “Stork-Friendly” agriculture to help combat the difficulties faced as a rural Japanese municipality including population decline, increased farmland abandonment, and falling rice prices. This thesis investigates how Toyooka City uses a pragmatic approach to achieve holistic sustainability that works within the framework of our current globalized cultural, political, social and economic landscape. By drawing on the fieldwork I conducted in Toyooka as well as the informal and …
