For all the opportunities that equine-assisted therapy provides there is little education on the practice. The focus of this project is to present the process, benefits and limitations of adopting an equine-assisted therapy course at California Polytechnic State University so it may be used as a reference for future course proposal.

Objective: The aim of this proposal is to offer insight into Equine-assisted therapy, understanding how to integrate the Professional Association of Therapeutic Horsemanship (PATH) International curriculum into the …

Laterality Is Linked To Personality In The Black-Lined Rainbowfish, Melanotaenia Nigrans, Culum Brown, Anne-Laurence Bibost

Sentience Collection

Emotions such as fear in vertebrates are often strongly lateralised, that is, a single cerebral hemisphere tends to be dominant when processing emotive stimuli. Boldness is a measure of an individual’s propensity to take risks and it has obvious connections with fear responses. Given the emotive nature of this well-studied personality trait, there is good reason to suspect that it is also likely to be expressed in a single hemisphere. Here, we examined the link between laterality and boldness in wild and captive-reared rainbowfish, Melanotaenia nigrans. We found that fish from the wild were bolder than those from captivity, which …

Beef Cattle Lesson Plans: For Use In The Education Of School-Age Children In The Beef Cattle Industry, Katherine M. Halloran, Cheyenne H. Love

Animal Science

This project was initially created for use at Fort Hope in Arroyo Grande, California. It designs lesson plans created to teach children about the beef cattle industry. The project consists of lesson plans for three age groups: 7-9, 10-12, and 13-15. Each age group will learn various aspects about beef cattle, and lessons will increase in complexity as the children advance age groups. The groups will spend six days in lecture completing worksheets and activities, and on the seventh day, after completion of a review game, the children receive certificates. While the project was created specifically for the Fort Hope …

The Effects Of Different Cryopreservation Techniques On The Survival Rate Of In Vitro Produced (Ivp) And Biopsied Bovine Blastocysts, Diana J. Gumber

Animal Science

This study’s objectives were to determine if the biopsy of expanded blastocysts prior to cryopreservation affected the survival rates and determine if there is a difference between slow-freezing in 10% glycerol, slow freezing in ethylene glycol, and vitrification in terms of survival rate of the embryos. Blastocoeles were reduced prior to cryopreservation by means of biopsy. Embryos for slow freezing were exposed to ethylene glycol (SynGRO Ethylene Glycol with Sucrose, BIONICHE, Pullman, WA, USA) or 10% glycerol (SynGRO 10% Glycerol, BIONICHE, Pullman, WA, USA) as cryoprotectants. Vitrified embryos were exposed to 10% and 40% ethylene glycol. Survival rate of biopsied …

Lamb Bacon: How The Method Of Brine Distribution And Addition Of A Dry Rub Influences Yields, Morgan Metheny

Animal Science

This study was conducted to test the whether lamb breasts can substitute as the raw material in producing a bacon product. Due to the difference in fat saturation between pork and lamb, this research was used to test how successful lamb absorbs the brine in order to make bacon. The yield results of two different processing techniques, injection and tumbling, were compared along with comparing the affect of adding a dry rub of seasonings to the lamb surface. The 120 lambs breasts were split into four groups of 30. Each group received a different treatment: plain tumbled, plain injected, seasoned …

New Species Records And Changes In Abundance Of Waterfowl In Northwest Greenland, K. K. Burnham, D. R. Sinnett, J. A. Johnson, J. L. Burnham, J. A. Baroch

United States Department of Agriculture Wildlife Services: Staff Publications

Breeding populations of Nearctic and Palearctic waterfowl have undergone significant changes in abundance and distribution over the past 50 years. The Avanersuaq District in northwest Greenland is home to an assemblage of waterfowl from both geographic areas; however, minimal historic or current information is available on species abundance. In 2008 and 2009, we conducted field surveys in Greenland from 76.00_ to 77.35_N for breeding and non-breeding waterfowl and have collected anecdotal field notes of avian observations over a 20-year period (1993–2012). During these periods, we documented the first observation of a Ross’s goose (Chen rossii) and the first confirmed breeding …

Assessing Rodent Species Counts And Diversity In The Not-Grazed Montana De Oro State Park And The Rotationally Grazed Pecho Ranch, Nancy Marie Lemos

Master's Theses

The available data examining the influence of rotational grazing on rodent responses are limited. This study investigated how rotational livestock grazing practices influence small mammal rodent abundances and species diversity. We looked for evidence of variation in the occurrence and/or numbers of certain rodent species among three plant community types (grassland, shrubland, grass-shrub mix), managed with or without grazing. We used Sherman live traps over a total of eight trapping sessions. We totaled 486 trapnights for each of the six plant community and grazing management combinations. The three plant community types were identified by visual cover.

Out of the eight …

Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell

National Invasive Species Council

Conclusion

The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.

An Hsi Fact Sheet: Avian Influenza In India, Humane Society International

HSI FACT SHEETS

Avian influenza (AI), commonly known as bird flu, typically causes little or no harm to its wild waterfowl hosts. In 2003-2004, however, nine Asian countries reported unprecedented outbreaks of high-mortality AI in domestic poultry. This viral lineage, subtype H5N1, has spread to over 60 countries, and is considered endemic in at least four.

In India, H5N1 outbreaks were first recorded in 2006, and have continued each year since, reaching a total of 86 by 2012. Millions of India’s chickens and ducks have been culled in efforts to contain and eliminate the virus. India has declared itself free of AI a …

The Effect Of Physical And Demographic Factors And Training On The Time-To-Adoption Of Domestic Cats In A Local Shelter, Deborah T. Stratton

Senior Honors Projects, 2010-2019

About 7.6 million animals enter shelters each year (Pet Statistics. (n.d.)). Many factors have been examined to determine what affects adoption rates for these companion animals. A study of a kill-shelter has found that age, gender, and circumstance all influenced cat adoption rates (Lepper et. al., 2002). Training was also found to increase the adoption rates of dogs (Luescher and Medlock, 2009). Data on cat adoptions were collected from Charlottesville-Albemarle SPCA (a no-kill shelter) and were analyzed using Sigma Plot and STATA. Training cats took place at Rockingham/Harrisonburg SPCA and the data was also analyzed using Sigma Plot. Color, age, …

Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2011, Jacob Manlove, Leah English, Jennie Popp, Wayne Miller

AAES Research Reports and Research Bulletins

Agricultural production, processing, and retail industries are major contributors to the Arkansas economy in terms of GDP. Agriculture contributes to the economy through direct agricultural production, value-added processing, and agricultural retail activities, and it also plays an important role through its interactions with other sectors. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy; thus agriculture remains a vital part of Arkansas’ economy. Part 1 of the report compares the relative size of the Agriculture and Food Sector in Arkansas with those of neighboring states, the Southeastern region of the …

Juvenile Domestic Pigs (Sus Scrofa Domestica) Use Human-Given Cues In An Object Choice Task, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Social Cognition Collection

Research on the comprehension of human-given cues by domesticated as well as non-domesticated species has received considerable attention over the last decade. While several species seem to be capable of utilizing these cues, former work with domestic pigs (Sus scrofa domestica) has shown inconclusive results. In this study, we investigated the use of human-given cues in an object choice task by young domestic pigs (N = 17; seven weeks of age) who had very limited human contact prior to the experiments. Subjects had to choose between two bowls of which only one was baited with a reward. Over the course …

Palatability Of Teff Grass By Horses, Rachel R. Cummins

Animal Science Undergraduate Honors Theses

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 …

Isoflupredone Acetate As Ancillary Therapy For Bovine Respiratory Disease In High-Risk Stocker Calves, Claire E. Crews

Animal Science Undergraduate Honors Theses

Bovine respiratory disease (BRD) is the leading cause of illness and death in U.S. feedlot cattle. This study evaluated the use of isoflupredone acetate in the treatment of BRD. Crossbred male beef calves (n = 192; BW = 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 …

A Male Spider’S Ornamentation Polymorphism Maintained By Opposing Selection With Two Niches, Bo Deng, Alex Estes, Brett Grieb, Douglas Richard, Brittney Hinds, Eileen Hebets

Eileen Hebets Publications

The Levene mechanism to maintain genotypic polymorphism by opposing selection on genotypes in multiple niches was proposed 60 years ago, and yet no systems were found to satisfy the mechanisms rather restrictive conditions. Reported here is such an example that a wolf spider population lives in a habitat of mixed rocks and leafy litter for which the females are phenotypically indistinguishable and the males have two distinct phenotypes subject to opposing selection with respect to the substrates. Census data is best-fitted to a population genetics model of the Levene type. A majority of the best fit support polymorphism, with many …

Balking Incidence And Behavioral Responses During Handling In Fed Cattle With Genetic And Carcass Implications, Michelle Lynn Thomas

Graduate Theses and Dissertations

Temperament in cattle is often defined as the reactivity to human handling or novel environments. Temperament differences have been shown among breed-type categories, within breed types, among crossbreds, and between sexes. Temperament tests are typically completed at weaning time on beef cattle, and rarely on fed Holstein steers for beef production. Balking behavior, or cease in forward motion, in the cattle working facility can pose welfare issues as the electric prod use to coerce movement is implemented. Three observational field projects were designed to evaluate balking behavior incidence in unknown breed-types at the processing plant, Holstein steers in the feedlot …

Choice And Control Of Enrichment For A Rescued And Rehabilitated Atlantic Bottlenose Dolphin (Tursiops Trunactus), Hannah Bahe

Honors Theses

Animals living under human care experience stress related to a lack of control over t environment. One way to remedy this is through the use of cognitive enrichment, su choice and control of enrichment. This type of enrichment has been shown to have benefits for animals under human care including increased activity and social interactions. To determine if choice and control was more beneficial than enrichmen alone, a three year old male Atlantic bottlenose dolphin (Tursiops truncatus) was ex to novel enrichment items in two experimental conditions. For the first condition, th animal was given a novel object. During the …

Formulas were designed to include 0, 50, 100, 150, and 200 ppm ingoing sodium nitrite or the equivalent from CP or SN, and 3 replicates of products were manufactured. Turkey and curing brines were tumbled, stuffed, and cooked to an internal temperature of 73.9^oC. Products were stabilized and sliced into 12 mm slices (physicochemical trait analysis) and 2 mm slices (sensory trait analysis). Physicochemical traits measured only on d 0 were …

Life History Tradeoffs And The Costs Of Reproduction In Arizona Bark Scorpions (Centruroides Sculpturatus), Michael Marie Webber

UNLV Theses, Dissertations, Professional Papers, and Capstones

Tradeoffs in life history evolution result from conflicts in the time and energy that can be simultaneously invested in activities such as growth, reproduction, and survival. Reproduction is an energetically costly activity for organisms, and is known to elicit alterations in the daily activity patterns of individuals. I investigated reproductive tradeoffs in the Arizona Bark Scorpion,Centruroides sculpturatus. To better understand the nature of tradeoffs in this species, I examined the influence of reproductive state on the predatory efficiency and thermal preference of reproductive females. Further, I examined the influence of reproductive activities (i.e. gestation) on the ability of reproductive females …

Pronghorn (Antilocapra Americana) Offspring Recruitment On The Carrizo Plain National Monument: Evaluating The Effects Of Low Population Density And Marginal Habitat Quality., Diego Ramirez Johnson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Demographic fluctuation among ungulate populations is strongly linked to variability in recruitment. Rates of recruitment are subject to various forms of density-dependent and density-independent regulation. For species which benefit from the presence of conspecifics, reduced population density can decrease rates of recruitment and trigger a decline in per capita growth. Termed the Allee effect, this scenario can cause demographic collapse and population extinction. For many ungulate species, predation on juveniles is reduced when the timing and distribution of births is synchronized within a local population. Because birth synchrony is density-dependent, it may act as a mechanism for the Allee effect …

Approaches To Canine Health Surveillance, Dan G. O'Neill, David B. Church, Paul D. Mcgreevy, Peter C. Thomson, Dave C. Brodbelt

Epidemiology Collection

Effective canine health surveillance systems can be used to monitor disease in the general population, prioritise disorders for strategic control and focus clinical research, and to evaluate the success of these measures. The key attributes for optimal data collection systems that support canine disease surveillance are representativeness of the general population, validity of disorder data and sustainability. Limitations in these areas present as selection bias, misclassification bias and discontinuation of the system respectively. Canine health data sources are reviewed to identify their strengths and weaknesses for supporting effective canine health surveillance. Insurance data benefit from large and well-defined denominator populations …

Exclusion Performance In Dwarf Goats (Capra Aegagrus Hircus) And Sheep (Ovis Orientalis Aries), Christian Nawroth, Eberhard Von Borell, Jan Langbein

Learning Ability Collection

Using a comparative approach, we investigated the ability of dwarf goats and sheep to use direct and indirect information about the location of a food reward in an object-choice task. Subjects had to choose between two cups with only one covering a reward. Before making a choice, subjects received information about the baited (direct information) or nonbaited cup (indirect information). Both goats and sheep were able to use direct information (presence of food) in the object choice task. After controlling for local enhancement, we found that goats rather than sheep were able to use indirect information (i.e., the absence of …

Goats Excel At Learning And Remembering A Highly Novel Cognitive Task, Elodie F. Briefer, Samaah Haque, Luigi Baciadonna, Alan G. Mcelligott

Sentience Collection

Introduction: The computational demands of sociality (maintaining group cohesion, reducing conflict) and ecological problems (extractive foraging, memorizing resource locations) are the main drivers proposed to explain the evolution cognition. Different predictions follow, about whether animals would preferentially learn new tasks socially or not, but the prevalent view today is that intelligent species should excel at social learning. However, the predictions were originally used to explain primate cognition, and studies of species with relatively smaller brains are rare. By contrast, domestication has often led to a decrease in brain size, which could affect cognition. In domestic animals, the relaxed selection pressures …

Hymenolepis Robertrauschi N. Sp. From Grasshopper Mice Onychomys Spp. In New Mexico And Nebraska, U.S.A., Scott Lyell Gardner, Brent A. Luedders, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola …

Investigating A Role For The Ccaat/Enhancer-Binding Protein Δ In The Developing Zebrafish, Alisha Jennifer Beirl

Dissertations and Theses

The CCAAT/enhancer-binding protein delta (C/EBPδ) is a highly conserved transcription factor capable of regulating numerous cell fate processes, such as cell growth, differentiation, proliferation and apoptosis. C/EBPδ is inducible during cellular stress responses, including inflammation and responses to growth factor deprivation or thermal stress. C/EBPδ is stress-inducible in a diversity of fishes, including the zebrafish Danio rerio; however, little is known about its role in fish development. Here I show that overexpression of C/EBPδ leads to severe developmental defects, including reduced body length, edema, liver malformation and retinal abnormalities. The proportion of individuals that display developmental abnormalities is significantly …

Testing The Feasibility Of Bioacoustic Localization In Urban Environments, Blaire O'Neal

USF Tampa Graduate Theses and Dissertations

Bioacoustics is a relatively new field of research focused on studying the acoustic signals of vocal animal species. The field has been a topic of interest for many years due its passive approach and avoidance of species-level limitations, such as tracking rare or nocturnal species. It has been used to locate birds in terrestrial environments; however, localization in urban environments remains unstudied. This research aims to fill the gap by attempting to estimate the location of 30 discrete calls in eight unique, urban environments. Sites represented two distinct traffic scenarios: moderate traffic and high traffic. Three system arrays of three …

A Literature Review On Injection-Site Lesions In Dairy Cows And Culling Decisions, Eric B. Parsons

Dairy Science

Currently dairy producers face particular problems concerning their culled cows and bulls, these problems must be addressed so dairy producers have the opportunity to improve the quality of beef produced from their cull dairy cows. At the moment, not much is known about culling decisions outside “break-even” numbers and poor cow conditioning. This literature review outlines the strategy behind culling decisions and looks into potential plans to develop progressive body conditioning and quality of meat sent to auction. Currently the dairy industry is not placing much demand into providing the livestock auctions and harvest plants with higher quality meat. This …

Fallow Bucks Attend To Vocal Cues Of Motivation And Fatigue, Benjamin J. Pitcher, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott

Sentience Collection

Vocalizations encode a range of information about the caller, and variation in calling behavior and vocal structure may provide listeners with information about the motivation and condition of the caller. Fallow bucks only vocalize during the breeding season and can produce more than 3000 groans per hour. Males modulate their calling rates, calling faster when other calling males and/or females are nearby. Groans also reveal caller fatigue, becoming shorter and higher pitched toward the end of the rut. Thus, fallow deer groans vary both over very short (minute to minute) and longer timescales (the rut). However, no studies have investigated …

Learning And Memory In The Port Jackson Shark, Heterodontus Portusjacksoni, Tristan L. Guttridge, Culum Brown

Sentience Collection

Basic understanding of the fundamental principles and mechanisms involved in learning is lacking for elasmobranch fishes. Our aim in this study was to experimentally investigate the learning and memory capacity of juvenile Port Jackson sharks, Heterodontus portusjacksoni. Sharks (N = 30) were conditioned over a 19-day period to associate an underwater LED light or stream of air-bubbles [conditioned stimulus (CS)] with a food reward [unconditioned stimulus (US)], using three procedures (delay, trace and control). During experiments, the CS signalled at a random time between 180 and 300 s for 30 s (six times per day). For the delay the US …
