Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick Mar 2024

Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick

SACAD: John Heinrichs Scholarly and Creative Activity Days

A comparison between the extent that sciurid specimens display vigilance and foraging behaviors on college campuses against specimens within urban environments. Observations of fox squirrels and western gray squirrels were taken from the Squirrel-Net behavioral database used for this project. We found there was a significant difference between the percent vigilance behaviors and foraging behaviors on college campuses compared to urban environments. This suggests that squirrels residing on college campuses are more desensitized to pedestrian activity and foot traffic compared to squirrels that inhabit urban areas.

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson Feb 2024

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson

People and Animals: The International Journal of Research and Practice

As incidences of substance use disorders (SUD) increase in the wake of the COVID-19 pandemic, there is a need for more effective treatment approaches. Further, treatment approaches currently available struggle to retain patients during the period of substance withdrawal in early treatment due to patients’ withdrawal symptoms including increased feelings of anxiety and depression. Withdrawal symptoms have been linked to dysregulated cortisol concentrations present in this period. Psychotherapy incorporating equine interaction (PIE) has emerged in other populations as a treatment that decreases cortisol concentrations and improves treatment retention. The present study investigated the impact of 4 weeks of PIE on …

Nutritional Evaluation Of Hydroponic Corn Fodder And Its Effect As Substitute For Feed Concentrates For Buffalo Calves, Charity I. Castillo, Phoebe Lyndia T. Llantada, Cyril P. Baltazar, Mary Rose D. Uy-De Guia, Reynald D. Amido, Arnel N. Del Barrio

The Philippine Agricultural Scientist

This study investigated the effects of hydroponic corn fodder on the growth performance of buffalo calves. Twelve Bulgarian Murrah buffalo calves were divided into two treatment groups: T1, fed with Napier grass and starter feed concentrates, and T2, fed with Napier grass, starter feed concentrates, and hydroponic corn fodder, replacing 50% of the starter feed concentrate. The study found no significant differences between the two groups' average total weight gain and average daily gain. However, the average daily feed intake was significantly higher in T2, possibly due to the tender and young nature of the hydroponic corn fodder. Dry matter …

The Influence Of Hiking Trails On Salamanders, Emily M. Macdonald Sep 2023

The Influence Of Hiking Trails On Salamanders, Emily M. Macdonald

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

Over half of the World’s salamanders are facing extinction. It is important to understand the impact Humans have on them in all parts of their ranges so we can better understand what they need and how we can prevent further extinctions. I conducted this study to try to determine if the human activity on the official hiking trails in the Arcata Community Forest in Arcata California; as designated by the official map of the Forest; is negatively impacting the salamanders that live in the Forest. I thought there would be an increase in the number of species and the overall …

Summary Of Methodology Used In Enterotoxigenic Escherichia Coli (Etec) Challenge Experiments In Weanling Pigs And Quantitative Assessment Of Observed Variability, Payton L. Dahmer, Joel M. Derouchey, Jordan T. Gebhardt, Chad B. Paulk, Cassandra K. Jones

Kansas Agricultural Experiment Station Research Reports

Post-weaning diarrhea in pigs can be caused by the F4 or F18 strains of enterotoxigenicEscherichia coli(ETEC). To evaluate interventions for ETEC, experimental infection via a challenge model is critical. To our knowledge, there is a lack of explanation for the variability in responses observed across ETEC challenge studies. Our objective was to quantitatively summarize the responses and variability among recent ETEC challenge studies and develop a tool for sample size calculation. The most widely evaluated response criteria across ETEC challenge studies are growth performance, fecal consistency and bacterial shedding, intestinal morphology, and immune responses. Factors that contribute to …

Kansas Agricultural Experiment Station Research Reports

Pigs are hosts forSalmonellaand Shiga toxin-producingEscherichia coli(STEC) and these pathogens can commonly be isolated from the pig farm environment. Pigs can carry pathogens to the abattoir and contaminate pork products, posing a risk to public health. Identifying an intervention that effectively reduces pathogens in commercial pigs before harvest is imperative. Due to the need for effective pre-harvest interventions in the pig industry, the objective of this study was to investigate BIOPLUS 2B (Bacillus licheniformisandBacillus subtilis) and Probicon L28 (Lactobacillus salivariusL28) as pre-harvest interventions to reduceSalmonellaand STEC in commercial …

Pelleting of feed has been demonstrated to be an effective mitigation strategy for porcine epidemic diarrhea virus (PEDV) contaminated feed but has not been evaluated for other endemic swine viruses like porcine reproductive and respiratory syndrome virus (PRRSV) or Seneca Valley virus 1 (SVV1). Therefore, the objective of this experiment was to evaluate the efficacy of pelleting to inactivate PEDV, PRRSV, and SVV1 inoculated feed. Ten replicates were conducted in the Cargill Feed Safety Research Center at Kansas State University (K-State) using a pilot scale mixer, bucket elevator, pellet mill (including conditioner and die), and cooler. First, a virus negative …

This trial was conducted to evaluate the optimum scale head settings for LeeO scale systems to balance accuracy, precision, and efficiency in weighing pigs. LeeO scales allow for the adjustment of both stabilization time (mSec) and stabilization weight (g). The pig weight that is accepted by the technology is only registered after staying within the set stabilization weight for the set stabilization time. Prior to beginning animal research, precision and accuracy were assessed for two scales. The nursery scale used a 25-lb test weight and the finisher scale used a 50-lb test weight. The CV estimates were 0.1% or less …

Evaluation Of Specialty Soybean Products And Organic Acids To Alter Nursery Dietary Acid-Binding Capacity-4 On Pig Performance And Fecal Dry Matter, Ethan B. Stas, Mike D. Tokach, Jason C. Woodworth, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt Jan 2023

Evaluation Of Specialty Soybean Products And Organic Acids To Alter Nursery Dietary Acid-Binding Capacity-4 On Pig Performance And Fecal Dry Matter, Ethan B. Stas, Mike D. Tokach, Jason C. Woodworth, Joel M. Derouchey, Robert D. Goodband, Jordan T. Gebhardt

Kansas Agricultural Experiment Station Research Reports

A total of 300 pigs (241 × 600, DNA; initially 12.4 lb) were used to evaluate specialty soybean products and organic acids to alter the acid-binding capacity-4 (ABC-4) level of the diet on nursery pig performance and fecal dry matter (DM). At weaning, pigs were allotted to 1 of 6 dietary treatments. Diet 1 was formulated with 12.0% specialty soy protein concentrate (AX3 Digest; Protekta; Plainfield, IN), 1.06% citric acid, and 0.5% fumaric acid to achieve an ABC-4 of 223 meq/kg. Diets 2 and 3 were the same as diet 1 except citric and fumaric acid were reduced by 50 …
