Effect Of Micro-Aid® Supplementation On Nitrogen Losses From Manure, Andrea K. Watson, Galen E. Erickson, Terry J. Klopfenstein Klopfenstein, Mike J. Rincker
Effect Of Micro-Aid® Supplementation On Nitrogen Losses From Manure, Andrea K. Watson, Galen E. Erickson, Terry J. Klopfenstein Klopfenstein, Mike J. Rincker
Nebraska Beef Cattle Reports
A 2x2 factorial designed experiment was used to study the effects of Micro-Aid and time on OM and N losses from manure, in a simulated feedlot pen setting. Manure was collected from cattle on a common diet, except for the addition of 1 g Micro-Aid /steer daily. Losses of OM were greater at 60 d than 30 d, and greater for control than Micro-Aid. Nitrogen losses at d 30 were similar between treatments but control pans had greater N losses at d 60. Feeding Micro-Aid to cattle may inhibit N volatilization from manure, enhancing the fertilizer value of manure.

Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass-type was the major contributor in determining the biochemical composition of L. dorsi steaks, with warm-season grasses causing increased concentrations of moisture and zinc and decreased concentrations of magnesium. Aging 28 days instead of 7 days increased pH and caused an increased concentration of carbohydrates, and non-heme and heme iron in B. femoris steaks. Diet, especially grass type, during grazing, can alter the end …
Grass Type, Grazing Supplementation, And Finishing Diets Affect Beef Fatty Acids, Kimberly A. Varnold, Chris R. Calkins, Brandon L. Nuttelman Nuttelman, Lasika S. Senaratne-Lenagala, Tommi F. Jones, Timothy P. Carr, Galen E. Erickson
Grass Type, Grazing Supplementation, And Finishing Diets Affect Beef Fatty Acids, Kimberly A. Varnold, Chris R. Calkins, Brandon L. Nuttelman Nuttelman, Lasika S. Senaratne-Lenagala, Tommi F. Jones, Timothy P. Carr, Galen E. Erickson
Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass type was the major contributor in determining the fatty acid profile, especially in the neutral lipid layer. Warm-season grasses decreased concentrations of most fatty acids compared to cool-season grasses. The provision of WDGS as an energy supplement while grazing dissipated any differences caused by grass type.
The Effects Of Diet And Cooler Aging On Specific Flavor Notes In Beef, Kimberly A. Varnold, Chris R. Calkins, Rhonda K. Miller Miller, Galen E. Erickson
The Effects Of Diet And Cooler Aging On Specific Flavor Notes In Beef, Kimberly A. Varnold, Chris R. Calkins, Rhonda K. Miller Miller, Galen E. Erickson
Nebraska Beef Cattle Reports
Crossbred steers (n = 64) were grazed on warm- or cool-season grass-dominated pastures, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Finishing on corn increased desirable flavor notes and decreasedundesirable flavor notes in both L. dorsi and B. femoris steaks. In addition, grazing on warm-season grasses increased the prevalence of undesirable flavors but was often dissipated by the addition WDGS supplementation. Longer aging periods tended to increase the prevalence of undesirable flavors, especially in B. femoris steaks. It is recommended producers provide WDGS supplementation, …
Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg
Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Background: A putative new species of Varestrongylus has been recently recognized in wild North American ungulates based on the ITS-2 sequences of larvae isolated from feces during a wide geographic survey. No taxonomic description was provided, as adult specimens were not examined. Methods: Lungworm specimens were collected in the terminal bronchioles of muskoxen from Quebec, and a woodland caribou from central Alberta, Canada. The L3 stage was recovered from experimentally infected slugs (Deroceras spp.). Description of specimens was based on comparative morphology and integrated approaches. Molecular identity was determined by PCR and sequencing of the ITS-2 region of …

Air Sac Nematode Monopetalonema Alcedinis In A Belted Kingfisher (Megaceryle Alcyon) In Maryland, Usa, Ellen Bronson, Kathleen Kelly, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Sporadic and geographically widespread reports of parasites affecting the Belted Kingfisher (Megaceryle alcyon) have been published but few have described details of the pathology. A female, adult kingfisher was found dead in a heavily wooded area of a zoo in Maryland, USA. At necropsy, numerous sexually dimorphic, 4.4–40.5-cm adult Monopetalonema alcedinis nematodes were found tightly wound within the coelomic cavity between organs and completely filling the caudal thoracic and abdominal air sacs. Abundant, 30–60-mm diameter, larvated, thick-walled ova were found in the bronchi and parabronchi, within the mesentery, and in the serosa of multiple coelomic organs. Monopetalonema alcedinis …

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand, anticipate, and respond …
The Current Prevalence Of Caprine Arthritis-Encephalitis Virus In Midwestern Goat Herds, Bradley Todd Jones Dvm
The Current Prevalence Of Caprine Arthritis-Encephalitis Virus In Midwestern Goat Herds, Bradley Todd Jones Dvm
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Caprine Arthritis-Encephalitis Virus (CAEV) is an incurable disease of goats that has both social and economic impacts. Clinical disease in goats includes encephalitis in kids; chronic arthritis, inflammatory mastitis and progressive respiratory disease in adults. In the last 25 years there have been significant changes in the US goat industry with rapid growth in the meat and dairy industries. Recent prevalence studies are lacking and historic studies may not reflect changes in the industry. The purpose of this study was to establish the prevalence of CAEV in Midwestern herds that are not routinely acquiring new animals from known negative CAEV …

Longitudinal research is well suited for investigating phenomena that change over time. With the growing acceptance of mixed methods, researchers are combining qualitative and quantitative approaches within longitudinal research. However, little attention has been paid to how researchers integrate longitudinal mixed methods databases. The purpose of this methodological review was to describe how researchers combine mixed methods and longitudinal approaches in practice and delineate dimensions and issues inherent within these complex designs. We examined published empirical studies from the health sciences that self-identified as longitudinal and mixed methods. Our results identify major dimensions, variations, and issues for designing longitudinal mixed …
