Welfare Of Non-Traditional Pets, Catherine A. Schuppli, David Fraser, H. J. Bacon
Welfare Of Non-Traditional Pets, Catherine A. Schuppli, David Fraser, H. J. Bacon
Wild and Exotic Animals as Pets Collection
The keeping of non-traditional or ‘exotic’ pets has been growing in popularity worldwide. In addition to the typical welfare challenges of keeping more traditional pet species like dogs and cats, ensuring the welfare of non-traditional pets is complicated by factors such as lack of knowledge, difficulties meeting requirements in the home and where and how animals are obtained. This paper uses examples of different species to highlight three major welfare concerns: ensuring that pets under our care i) function well biologically, ii) are free from negative psychological states and able to experience normal pleasures, and iii) lead reasonably natural lives. …
The Pit Bull's Discourse: An Examination Of Discursive Construction, Karen Jennings
The Pit Bull's Discourse: An Examination Of Discursive Construction, Karen Jennings
Bridges: A Journal of Student Research
Since the early 1980s, news reporters have used the pit bull as a scapegoat to get media attention by plastering the frightening image of a snarling, bloody dog across all news outlets. Over the years, the pit bull's image has suffered major blows to its already battered reputation with every new "dog attack" news story published. Each reporter's word choice, in both past and present news stories, has an effect on the reader's perception of the topic. By analyzing several unrelated stories about pit bulls, both good and bad, I reveal how word choice alone shapes a reader's perception while …

Distribution, Habitat Preference, And Status Of The Ditch Fencing Crayfish, Faxonella Clypeata (Hay) (Decapoda: Cambaridae), In Arkansas, H. W. Robison, C. T. Mcallister
Journal of the Arkansas Academy of Science
The ditch fencing crayfish, Faxonella clypeata (Hay), is a common and widespread crayfish that inhabits roadside ditches, intermittent first-order streams, shallow sloughs with heavy vegetation, and edges of swamps in Arkansas. Between 1997-2012, we made 55 collections of F. clypeata in 34 counties throughout eastern Arkansas, including 23 counties where F. clypeata had not been previously documented. At most of these locations within the West Gulf Coastal and Mississippi Alluvial Plain provinces, F. clypeata was found to be a locally abundant crayfish. With regard to conservation status, F. clypeata should be considered as “Currently Stable” due to its widespread distribution …

Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp
Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp
Theses and Dissertations--Animal and Food Sciences
Lameness and mastitis are the two most costly diseases in the dairy industry. Reduction of these diseases through housing and management is beneficial. Compost bedded pack (CBP) and sand freestall barns were compared in a long-term, on-farm study to assess the effect of housing on each disease. Another research objective was to evaluate the effects of ambient weather conditions on moisture and 20 cm internal temperature of CBP. Compost bedded pack moisture, C:N ratio, and internal temperature effects on cleanliness, mastitis, and bedding bacterial counts were also considered. The last research objective was to evaluate the economics of bedding material …
Isoflupredone Acetate As Ancillary Therapy For Bovine Respiratory Disease In High-Risk Stocker Calves, Claire Crews, Jeremy Powell, Elizabeth Kegley, Jana Reynolds, Pete Hornsby
Isoflupredone Acetate As Ancillary Therapy For Bovine Respiratory Disease In High-Risk Stocker Calves, Claire Crews, Jeremy Powell, Elizabeth Kegley, Jana Reynolds, Pete Hornsby
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Bovine respiratory disease (BRD) is the most prevalent and devastating disease in U.S. feedlot cattle. This study evaluated the use of isoflupredone acetate in the treatment of BRD. Crossbred male beef calves (n = 192; body weight = 221 ± 3.9 kg) were acquired in two blocks from regional auction markets and transported to the University of Arkansas Stocker and Receiving Cattle Unit. Calves were observed daily for signs of respiratory illness. Antibiotic treatment was administered if calves displayed signs of respiratory illness and rectal temperature was ≥40 °C. Calves (n = 72) requiring antibiotic treatment were assigned randomly to …
Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon
Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested for safety if accidently overfed to broiler breeders. In order to simulate a feed mixing error at a feed mill, Improved Milbond-TX® was overfed to broiler breeders to see if this would cause any negative effects on bird performance. A typical corn-soybean based diet supplemented with Milbond-TX mycotoxin binder at three different levels of inclusion (0%, 0.5%, and 1%) was fed to …

Steer Stress Response As Affected By Genotype And Transportation, Megan Wary, Marites Sales, Ben Williamson, Ken Coffey, Michael Looper, Charles Rosenkrans Jr.
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Bovine cytochrome P450 3A28 is responsible for metabolizing ergot alkaloids that cattle ingest when feeding on endophyte-infested tall fescue grass. The objective of this research was to determine associations among genotype, transportation, and stress responses. Angus crossbred steers (n = 47) were genotyped (CC, CG, or GG) for a single-nucleotide polymorphism (C994G) in cytochrome P450 3A28. Genotypes were determined by polymerase chain reaction (PCR) amplification followed by restriction enzyme (Alu1) digestion. Steers were backgrounded on a mixed-cultivar tall fescue pasture. Following the stocker phase, steers were transported to the feedlot for finishing. Stress responses were determined 27 h prior to, …

Palatability Of Teff Grass By Horses, Rachel R. Cummins, Kenneth Coffey, Nancy Jack, Kathleen Jogan, Edward Gbur, Robert Rhein, Dirk Philipp, Melissa Adams, William Smith, Katherine Clayton
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Most forages commonly used to feed horses have potential detriments including blister beetles or excessive fiber concentrations. Teff grass (T), a warm-season annual forage, has the potential to be a good alternative for horses because of its lack of observed disorders. Our objective was to compare preference by horses for T harvested under different conditions with that of bermudagrass (B) harvested at two maturities. Six different forages were evaluated: T harvested at the late vegetative stage (TLV), at late bloom but that incurred 33 mm of rainfall between mowing and baling (TLBR), with caryopsis visible (TES), or at soft dough …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The Ozark bass (Ambloplites constellatus) is endemic to the Upper White River Basin, and a limited amount of information exists on the Ozark bass population, including growth and mortality characteristics. The purpose of this study was to determine growth and mortality of Ozark bass in the Upper White River Basin, compare growth of Ozark bass to other Ambloplites species, and compare growth and mortality of Ozark bass between sample sites. Sampling occurred in Crooked Creek and in the Lower Wilderness Area (LWA) of the Buffalo River, with multiple collections from each body of water. Sampling occurred during summer 2013 via …
Modulation Of Variation By Response-Reward Spatial Proximity, Kenneth J. Leising, Chad M. Ruprecht, W. David Stahlman
Modulation Of Variation By Response-Reward Spatial Proximity, Kenneth J. Leising, Chad M. Ruprecht, W. David Stahlman
Psychological Science Articles
There has been a recent surge in the experimental investigation of the control of behavioral variability. Currently, it is understood that variability in behavior is predictably modulated by reinforcement parameters (e.g., a probability of reward delivery and reward magnitude). In two experiments, we investigated how spatial proximity between response and reward locations impacts the production of behavioral variability in both response rate and lever press duration. Rats were trained to lever press on two levers in a standard operant chamber that only differed from one another in their proximity to a food niche (i.e., Near vs. Far); a second experimental …

A Qualitative Assessment Of Virginia Beach Dog Park Users, Edwin Gómez, John Hunting
Human Movement Studies & Special Education Faculty Publications
The purpose of this paper is to look at a Virginia Beach, Virginia (VA) dog park as a case study exploring the benefits and perceptions of dog parks by its users. The qualitative methodology follows an earlier dog park study by Gómez (2013) in Norfolk, VA. Our findings indicated three major themes: (a) dog exercise, (b) socialization for dogs (and humans), and (c) safe off-leash place. Findings from Virginia Beach are compared to earlier findings in Norfolk.

Growth And Reproduction In The Ouachita Madtom (Noturus Lachneri) At The Periphery Of Its Distribution, R. Tumilson, J. O. Hardage
Journal of the Arkansas Academy of Science
The Ouachita madtom (Noturus lachneri) occurs primarily in drainages of the upper Saline River and in a few small tributaries to the Ouachita River in Arkansas, USA. We collected specimens by hand and by use of aquarium dipnets on 29 occasions from 20 October 1999 through 25 July 2000 in Cooper Creek, presently a feeder creek into Lake Catherine on the Ouachita River. Total length was measured, reproductive attributes were noted, and individuals were released at the capture site (with exception of 3 gravid females retained to assess fecundity). We recognized 2 age (size) classes during most of the year …

Toad (Anura: Bufonidae) Limb Abnormalities From An Aquatic Site In Scott, Pulaski County, Arkansas, C. S. Thigpen, D. Beard, S. E. Trauth
Journal of the Arkansas Academy of Science
We collected and examined 16 Fowler’s toads, Anaxyrus fowleri, and one dwarf American toad, Anaxyrus americanus charlesmithi, in central Arkansas in 2011. Collection was initiated by observation of abnormal toads. Toads were euthanized, measured, photographed, and deposited in the Arkansas State University herpetological collection. Several toads were radiographed. We found various abnormalities in both forelimbs and hindlimbs and on both sides of the body. The causes of the abnormalities remain unknown and will require further studies to determine if the environment is imperiled.

Long-Term Impacts Of Adolescent Risperidone Treatment On Behavioral Responsiveness To Olanzapine And Clozapine In Adulthood, Jing Qiao, Qinglin Zhang, Ming Li
Department of Psychology: Faculty Publications
This preclinical study investigated howa short-termrisperidone treatment in adolescence impacts antipsychotic response to olanzapine and clozapine in adulthood. Antipsychotic effect was indexed by a drug's suppressive effect on avoidance responding in a rat conditioned avoidance response (CAR) model. Male adolescent Sprague–Dawley rats were first treated with risperidone (1.0mg/kg, sc) or sterile water and tested in the CAR model for 5 consecutive days from postnatal days P 40 to 44. After they became adults (~P 80–84), they were switched to olanzapine (0.5mg/kg, sc), clozapine (5.0mg/kg, sc) or vehicle treatment and tested for avoidance for 5 days. During the adolescent period, repeated …

Sorting Sheep And Goats In Medieval Iceland And Greenland Local Subsistence, Climate Change, Or World System Impacts?, Thomas Mcgovern, Ramona Harrison, Konrad Smiarowski
Publications and Research
Large archaeofaunal collections recovered from Viking Age and Medieval sites in Iceland and Greenland during intensive collaborative fieldwork over the past decade have demonstrated a diverging pattern in sheep and goat (caprine) management after ca. 1200 CE in the two Norse communities. Since Landnám (first settlement), flocks in both places contained a mixture of sheep and goats and survivorship profiles suggest a very mixed milk-meat-wool production strategy. By the late 13th century Icelandic herds were nearly all sheep, and zooarchaeological evidence suggests an increasing focus on wool production. Greenlandic archaeofauna indicate that farmers maintained the old Viking Age pattern …
Characterization Of The Discriminative Stimulus Properties Of The Atypical Antipsychotic Amisulpride In C57bl/6 Mice, Timothy J. Donahue
Characterization Of The Discriminative Stimulus Properties Of The Atypical Antipsychotic Amisulpride In C57bl/6 Mice, Timothy J. Donahue
Theses and Dissertations
Amisulpride, a benzamide derivative, is an atypical antipsychotic drug used to treat both schizophrenia and depression. Amisulpride is a selective antagonist at dopamine D2 and D3 receptors and at serotonin 5-HT2B and 5-HT7 receptors and displays an atypical clinical profile with reduced extrapyramidal motor effects. The drug has a chiral center and is a mixture of two optical isomers: (S)-amisulpride and (R)-amisulpride. The present study used a two-lever drug discrimination assay to allow a direct comparison between amisulpride and its two isomers. Additionally, substitution testing was conducted with the typical antipsychotics, atypical antipsychotics, antidepressants, …

Spatial Analysis Of Factors Influencing Long-Term Stress In The Grizzly Bear (Ursus Arctos) Population Of Alberta, Canada, Mathieu Bourbonnais, Trisalyn Nelson, Mark Cattet, Chris T. Darimont, Gordon Stenhouse
Physiology Collection
Non-invasive measures for assessing long-term stress in free ranging mammals are an increasingly important approach for understanding physiological responses to landscape conditions. Using a spatially and temporally expansive dataset of hair cortisol concentrations (HCC) generated from a threatened grizzly bear (Ursus arctos) population in Alberta, Canada, we quantified how variables representing habitat conditions and anthropogenic disturbance impact long-term stress in grizzly bears. We characterized spatial variability in male and female HCC point data using kernel density estimation and quantified variable influence on spatial patterns of male and female HCC stress surfaces using random forests. Separate models were developed for regions …

Dogs offer unique opportunities to study correlations between morphology and behavior because skull shapes and body shape are so diverse among breeds. Several studies have shown relationships between canine cephalic index (CI: the ratio of skull width to skull length) and neural architecture. Data on the CI of adult, show-quality dogs (six males and six females) were sourced in Australia along with existing data on the breeds’ height, bodyweight and related to data on 36 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49) collected internationally using the Canine Behavioral Assessment and Research Questionnaire …
