Microbial Colonization Of The Cloacae Of Nestling Tree Swallows, Tamara K. Mills, Michael P. Lombardo, Patrick A. Thorpe Jan 1999

Microbial Colonization Of The Cloacae Of Nestling Tree Swallows, Tamara K. Mills, Michael P. Lombardo, Patrick A. Thorpe

Peer Reviewed Publications

Microbes have the potential to be important selective forces in many aspects of avian biology. Microbes can affect fitness as a result of either their pathogenic or beneficial effects on host health. Little is known about the chronology of microbial colonization of nestlings or the effects of microbes on fledgling condition. We set out to (1) characterize the time course of microbial colonization of the cloacae of nestling Tree Swallows (Tachycineta bicolor), (2) examine the relationship between cloacal microbes and fledgling condition, and (3) determine if nest mates had similar assemblages of cloacal microbes. We repeatedly measured nestlings …

Modeling The Msx Parasite In Eastern Oyster (Crassostrea Virginica) Populations. I. Model Development, Implementation, And Verification, Susan Ford, Eric Powell, John Klinck, Eileen Hofmann Jan 1999

Modeling The Msx Parasite In Eastern Oyster (Crassostrea Virginica) Populations. I. Model Development, Implementation, And Verification, Susan Ford, Eric Powell, John Klinck, Eileen Hofmann

CCPO Publications

A mathematical model simulating the host-parasite-environmental interactions of eastern oysters (Crassostrea virginica) and the pathogen, Haplosporidium nelsoni, which causes MSX disease, has been developed. The model has 2 components. One replicates the infection process within the oyster and the other simulates transmission. The infection-development component relies on basic physiological processes of both host and parasite, modified by the environment, to reproduce the observed annual prevalence cycle of H. nelsoni. Equations describing these rates were constructed using data from long-term field observations, and field and laboratory experiments. In the model, salinity and temperature have direct effects upon …

Fisheries, Animal and Veterinary Sciences Faculty Publications

An epizootic causing mortality among cultured summer flounder Paralichthys dentatus occurred in summer of 1998 at a land-based facility on Narragansett Bay, Rhode Island, USA. The disease, flounder infectious necrotizing enteritis (FINE), was characterized by reddening around the anal area, distended abdomens filled with opaque serosanguineous fluid, enteritis and necrosis of the posterior intestine. In extreme cases of the disease, the posterior intestine was detached from the anus and was observed coming out the vent. The intestine of individuals that recovered from the dsease ended in a blind-sac; the abdomens of these fish were distended, due to food and water …

Glycolytic Inhibition In Pre-Rigor Muscle: An Alternative Method To Improve Beef Tenderness, Chris R. Calkins, Nancy Jerez, Jesus Velazco Jan 1999

Glycolytic Inhibition In Pre-Rigor Muscle: An Alternative Method To Improve Beef Tenderness, Chris R. Calkins, Nancy Jerez, Jesus Velazco

Nebraska Beef Cattle Reports

Flank muscle (FM) and loin eye muscle (LEM) were marinated with solutions of different glycolytic inhibitors to test their effect on tenderness, pH and color. The increase of pH was more evident in LEM than in FM. The improvement in tenderness was higher in FM. In LEM, the most desirable result (cherry-red color and more tender) was observed with sodium citrate. Flank muscle became more tender and had better color (cherry red) than the control with oxamic acid, iodoacetate, glucose and sodium acetate. Most of the compounds caused different responses between muscles. Potential inhibitors must be tested further to prove …

Feedlot Marketing/Sorting Systems To Reduce Carcass Discounts, Rob Cooper, Terry J. Klopfenstein, Todd Milton, Dillon Feuz Jan 1999

Feedlot Marketing/Sorting Systems To Reduce Carcass Discounts, Rob Cooper, Terry J. Klopfenstein, Todd Milton, Dillon Feuz

Nebraska Beef Cattle Reports

A project involving 4,348 cattle and five commercial feedlots in Nebraska was conducted to evaluate marketing/ sorting systems to reduce overweight and overfat carcasses . At reimplant time, cattle were weighed and fat depth estimated either by ultrasound or by manual rib palpation. Cattle heavier and/or fatter than a predetermined weight and fat depth were identified for early sale. The system of sorting did not reduce carcass discounts. Reimplant fat depth was poorly correlated to carcass fat depth. At reimplant time (~90 days prior to slaughter), we were unable to consistently identify cattle which would become Yield Grade 4 carcasses.

Corn And Sorghum Distillers Grains For Finishing Cattle, Ki Fanning, Todd Milton, Terry J. Klopfenstein, Mark Klemesrud Jan 1999

Corn And Sorghum Distillers Grains For Finishing Cattle, Ki Fanning, Todd Milton, Terry J. Klopfenstein, Mark Klemesrud

Nebraska Beef Cattle Reports

To evaluate corn and sorghum distillers grains in corn-based finishing diets, 60 crossbred, yearling steers were individually fed one of three finishing diets: dry-rolled corn, corn distillers grain or sorghum distillers grain for 127 days. Distillers grains were fed at 30 percent of the dietary dry matter, replacing dry-rolled corn. Distillers grains increased the final weight, daily gain, feed efficiency, hot carcass weight, fat thickness and yield grade compared with the control. Sorghum distillers grains increased dry matter intake and fat thickness compared with corn distillers grains.

Fat Addition And Restricted Feeding Of Corn Gluten Feed Diets For Cattle Exposed To Environmental Stress, Jill Heemstra, Terry L. Mader, Tony Scott, John Gaughan

Nebraska Beef Cattle Reports

One winter and one summer trial were conducted comparing dry rolled corn (DRC) to DRC + corn gluten feed (CGF) finishing diets. No performance differences among winter study treatment groups were found. In the 106- day summer trial, DRC or CGF (40 percent DM)-based diets were fed as high-energy, 8 percent roughage diets either ad libitum (HE), restricted to approximately 90 percent of HE (RE) or fed as moderate energy, 20 percent roughage diets (HR). Feeding CGF diets or lowering metabolizable energy (ME) intake through RE or HR diet regimes did not improve feed to gain ratios or appear to …

Steer Performance Within Summer Grazing Systems, D. J. Jordon, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams, Todd Milton, Rob Cooper Jan 1999

Steer Performance Within Summer Grazing Systems, D. J. Jordon, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams, Todd Milton, Rob Cooper

Nebraska Beef Cattle Reports

A growing/finishing trial in 1996-97 evaluated summer grazing systems and subsequent finishing performance. Steers were wintered on cornstalks and assigned to one of three summer grazing systems: 1) Sequential removal of cattle from bromegrass, 2) Bromegrass/warm season grass, or 3) Sandhills range. Steers on the sequential bromegrass treatment gained fastest in the summer, but had a higher slaughter breakeven. Sequential bromegrass, steers were on grass where cost of grain was fixed, for fewer days; therefore, breakeven was increased. Steers on the bromegrass/ warm-season treatment had the lowest slaughter breakevens due to more total weight gain on forage. Slaughter breakevens were …

Calf Performance Grazing Crop Residues In Combination With Rye In Fall And Winter, D. J. Jordon, Mark Blackford, Todd Milton, Terry J. Klopfenstein, Rob Cooper Jan 1999

Calf Performance Grazing Crop Residues In Combination With Rye In Fall And Winter, D. J. Jordon, Mark Blackford, Todd Milton, Terry J. Klopfenstein, Rob Cooper

Nebraska Beef Cattle Reports

Two trials in the fall and winter of 1997-98 evaluated calf performance when grazing either rye with crop residues or crop residues alone. While not significant, calves grazing rye followed by corn residues tended to gain faster compared to calves grazing residues alone (2.26 versus 1.84 lb/d, respectively). Calves grazing corn residues only fully compensated for the weight difference at the end of winter grazing by slaughter. No differences were found in finishing performance or slaughter breakevens. In trial 2, steers grazed rye and milo or milo residue alone. Steers grazing rye/milo gained faster (P < .05). Using rye to supplement animals on milo residues resulted in steers not leaving the rye portion of the field.

Evaluation Of Revalor®-G As An Initial Implant For Yearling Steers, Terry L. Mader, Jill Heemstra, Robert Brandt Jr., Gary Sides Jan 1999

Evaluation Of Revalor®-G As An Initial Implant For Yearling Steers, Terry L. Mader, Jill Heemstra, Robert Brandt Jr., Gary Sides

Nebraska Beef Cattle Reports

Three hundred thirty-six English crossbred steers (715 lb) were used to compare effects of reimplanting with Revalor®-S (administered on day 66) after three different initial implants (administered on day zero), to single implantation with Revalor-S (administered on day zero or day 66). Over the entire study, implanted steers gained faster and more efficiently than non-implanted control steers. Steers implanted initially with Revalor-G or Synovex-S gained faster than steers implanted only once. Of the three reimplant treatments, only those initially implanted with Revalor-G had improved feed efficiency compared with single-implanted steers on a live basis. Compared to non-implanted controls, marbling score …

Performance Of Yearling Steers Fed Beet Pulp Or Chicory Pulp Rations, Ivan G. Rush, Brad Van Pelt Jan 1999

Performance Of Yearling Steers Fed Beet Pulp Or Chicory Pulp Rations, Ivan G. Rush, Brad Van Pelt

Nebraska Beef Cattle Reports

Substitution of beet pulp or chicory pulp for corn silage was evaluated in a 64-day feeding trial using yearling steers. Rations contained 27.7 percent (DM) beet pulp or chicory pulp. Chicory pulp utilized in this trial is a suitable feed resource for beef cattle. Feed intake was significantly lower with chicory pulp addition. Palatability or very high water content of rations which reduced ration quality are potential reasons for decreased consumption of rations containing chicory pulp.

Dietary Management For Starting Finishing Yearling Steers On Feed, Burt Weichenthal, Ivan G. Rush, Brad Van Pelt Jan 1999

Dietary Management For Starting Finishing Yearling Steers On Feed, Burt Weichenthal, Ivan G. Rush, Brad Van Pelt

Nebraska Beef Cattle Reports

Angus crossbred yearling steers were started on a finishing program with diets stepped-up in grain over 23 days or with limit-feeding of the final diet over three weeks. Limit-feeding during start-up improved overall feed efficiency, carcass dressing percentage and fat thickness, but did not affect daily gain or carcass quality and yield grades. In this small pen research trial, steers reached ad libitum intake of the final diet by limit-feeding of this diet during start-up without major problems from acidosis or related intake variation.

Survey Of Medium And Large Mammals In An Urban Park (Murray Park), Little Rock, Pulaski County, Arkansas, Josie H. Dickins, David W. Clark, Steffany C. White, Gary A. Heidt

Journal of the Arkansas Academy of Science

Because of increased environmental awareness by city planning commissions, there are more urban parks and greenbelt areas. These areas often result in increased human and wildlife contacts, thus resulting in the need for management plans regarding urban wildlife. From September 1998 to March 1999, we conducted mammal surveys of the urban greenspace Murray Park, Little Rock, Pulaski County, Arkansas. Surveys were conducted using five methods: direct observations; spot lighting; live trapping; animal sign; and scent posts. Species recorded included, opossum (Didelphis virginiana), nine-banded armadillo (Dasypus novemcinctus), fox squirrel (Sciurus niger), gray squirrel (Sciurus carolinensis), beaver (Castor canadensis), woodchuck (Marmota monax), …

Effects Of Predation On Two Species Of Stream-Dwelling Crayfish (Orconectes Marchandi And Cambarus Hubbsi) In Pool And Riffle Microhabitats, Heidi Dukat, Daniel D. Magoulick Jan 1999

Effects Of Predation On Two Species Of Stream-Dwelling Crayfish (Orconectes Marchandi And Cambarus Hubbsi) In Pool And Riffle Microhabitats, Heidi Dukat, Daniel D. Magoulick

Journal of the Arkansas Academy of Science

Community structure may be governed by many abiotic and biotic factors. Of the biotic factors, predation is often considered to be critical in structuring freshwater stream communities. In the Warm Fork of the Spring River, the crayfish Cambarus hubbsi is found mainly in riffles, whereas the crayfish Orconectes marchandi is found in high numbers in pools. We hypothesized that predation, mainly by fish, is a factor causing this segregation. Higher predation rates for C. hubbsi than 0. marchandi in the pools and higher predation rates for 0. marchandi than C. hubbsi in the riffles were expected. A transplant tethering experiment …

Survey Of Diseases In Wild Turkeys In Arkansas, Wayne E. Thogmartin, James E. Johnson, Bradley A. Schaeffer, Camille C. Ciriano

Journal of the Arkansas Academy of Science

Nineteen dead wild turkeys were necropsied and 573 live wild turkeys were physically examined for pathological agents in Arkansas between 1992 and 1997 to determine the proximate role disease may play in declining wild populations in Arkansas. Necropsy of the dead wild turkeys identified avian pox and histomoniasis as the most common diseases (16% and 11% of necropsies, respectively). Avian pox was recorded from three major physiographic regions in the state (Ozark Highlands, Ouachita Mountains, Gulf Coastal Plain). One hen died of non-accidental crop impaction, the fifth occurrence observed in the southeastern United States. Another hen died after developing severe, …

Post-Metomorphic Growth And Reproduction In The Eastern Narrowmouth Toad (Gastrophryne Carolinensis) From Northeastern Arkansas, Stanley E. Trauth, Walter E. Meshaka Jr., Robert L. Cox Jr.

Journal of the Arkansas Academy of Science

Post-metamorphic growth and the reproductive cycle of the eastern narrowmouth toad (Gastrophryne carolinensis) were studied from 204 individuals collected during the April August 1989 activity season in a two-county area of northeastern Arkansas near the northwestern edge of the species' geographic range. Late summer metamorphs require a full growing season before they can reproduce as they approach their second year of life. The oldest individuals may be at least five years old. By late April, gonadal cycles of adults had commenced; the males were producing sperm, and some of the females were gravid. Fertility of both sexes increased during the …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck Jan 1999

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck

All Master's Theses

Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Improving Feed Grains, Bruce P. Mullan Jan 1999

Improving Feed Grains, Bruce P. Mullan

Journal of the Department of Agriculture, Western Australia, Series 4

Clearly, to encourage grain growers to focus their production systems towards feed grains, it is important to first identify the reasons for variation in the nutritional value of grains and then to develop rapid, cheap, and accurate methods of measuring these factors. The analytical methods should ideally be suitable for application either at the site of grain delivery from the farm or within the place of stockfeed manufacture. This will mean the nutritional value of the grain can be known before it is used. The rational marketing of feed grains could then be achieved, with the benefits from more efficient …

Postembryonic Development Of The Neural Lamella Of The Hypocerebralganglion In Melanogryllus Desertuspall. (Orthoptera, Gryllidae), Hati̇ce Karaki̇şi̇, Sema İşi̇sağ

Turkish Journal of Veterinary & Animal Sciences

The sheath of the hypocerebral ganglion was divided into two parts: an outer layer, the neural lamella and an inner layer, the perilemma. Dark and light types of glial cells were identified in the perilemma. In the 4th and 7th nymphal stages, some fibrous material related to the neural lamella accumulated in the light glial cells. It was surrounded by rough endoplasmic reticulum membranes and was then transported towards te outer parts of the sheath. Finally, it was bound to and intermingled with the lamella. These observations indicate that the 4th and 7th nymphal stages are critical for the development …

Lectin And Neuropeptide Labeling In Whole-Mount Preparation Ofmeninges In The Rat, Zafer Soygüder Jan 1999

Lectin And Neuropeptide Labeling In Whole-Mount Preparation Ofmeninges In The Rat, Zafer Soygüder

Turkish Journal of Veterinary & Animal Sciences

The distribution of both peptidergic and non-peptidergic primary afferents in meninges was investigated in whole-mount preparations from meninges. Lectin Griffonia simplicifolia I-B4 (GSA I-B4) was used as a marker for non-peptidergic fibres. Calcitonin gene-related peptide (CGRP) was used as a marker for peptidergic fibers. Lectin Griffonia simplicifolia selectively labeled thin sensory axons that were distributed throughout meninges unrelated to blood vessels. CGRP immunoreactive axons, in contrast, were found to be very close to vascular patterns. This study demonstrates that lectin-positive fibres are constituted by a fibre population separate from those containing neuropeptides.
