Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding Dec 2019

Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding

Animal Science Undergraduate Honors Theses

Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in …


The Effects Of Pre And Post Exercise Low-Level Laser Therapy On Biochemical Markers Of Skeletal Muscle Fatigue In Equines, Carson Freeman May 2019

The Effects Of Pre And Post Exercise Low-Level Laser Therapy On Biochemical Markers Of Skeletal Muscle Fatigue In Equines, Carson Freeman

Animal Science Undergraduate Honors Theses

Our objective was to determine whether administering low-level laser therapy before or after exercise had the greatest effect on biochemical markers of skeletal muscle fatigue in equines such as cortisol and blood lactate. Twelve quarter horses were divided into three groups: Group A received no laser therapy, Group B received laser therapy before exercise, and Group C received laser therapy after exercise. A Class II ERCHONIA ® PL500 handheld low-level laser was utilized for treatment with a wavelength of 635nm. Exercise was utilized using a horse walker system for 30 minutes five days a week for three weeks. Blood was …


Observations And Applications Of Husbandry Methodologies On A Backyard Poultry Farm In Dangriga, Belize, Bailey Carpenter May 2019

Observations And Applications Of Husbandry Methodologies On A Backyard Poultry Farm In Dangriga, Belize, Bailey Carpenter

Animal Science Undergraduate Honors Theses

This study explores the husbandry methodologies on a backyard poultry farm in Dangriga, Belize, with the purpose of producing a set of guidelines for backyard poultry growers that have limited resources in similar regions. The majority of data collection occurred through survey questions approved by the IRB, necropsies approved by IACUC, and general observations. There has been a steady increase in poultry production in developing regions due to its positive effects on income and relative nutrition. However, due to a lack of accessible communication and education regarding effective and safe poultry production, these operators typically see poor productivity and/or profitability …


Determining The Relationship Among Cattle Genotype, Hair Coat Score, And Productivity Through The Investigation Of Single Nucleotide Polymorphisms Within Prolactin, Dopamine Receptor D2, And Melatonin Receptor 1a, Erin Davis May 2019

Determining The Relationship Among Cattle Genotype, Hair Coat Score, And Productivity Through The Investigation Of Single Nucleotide Polymorphisms Within Prolactin, Dopamine Receptor D2, And Melatonin Receptor 1a, Erin Davis

Animal Science Undergraduate Honors Theses

Prolactin (PRL), melatonin (MTN), and dopamine (DA) are all hormones that are believed to play a role in the regulation and growth of hair in beef cattle. There are also single nucleotide polymorphisms associated with each of these hormones or their receptors, indicating that the investigation of these polymorphisms could allow them to serve as genetic markers for the future productivity of an animal. The objective of this study was to determine the relationships among cattle genotype, hair coat score, and productivity through the investigation of single nucleotide polymorphisms within prolactin, dopamine receptor D2, and melatonin receptor 1A. Body weights, …


The Effects Of Eicosapentaenoic Acid (Epa) And Docosahexaenoic Acid (Dha) On Brown Adipogenesis In Stem Cell Culture, Darynne Dahlem May 2019

The Effects Of Eicosapentaenoic Acid (Epa) And Docosahexaenoic Acid (Dha) On Brown Adipogenesis In Stem Cell Culture, Darynne Dahlem

Animal Science Undergraduate Honors Theses

Polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are major maternal dietary supplements due to their positive benefits on neurological tissue growth during the first 12 weeks of gestation. Previous studies show that EPA and DHA inhibit muscle formation but promote adipogenesis. However, no research has addressed the question whether high intake of EPA and DHA affects brown fat development during gestation. The objective of this study was to measure the effect of EPA and DHA supplement on brown adipogenesis and potential pathways related to mitochondrial biosynthesis using fibroblasts as in vitro model. Using Oil-Red-O staining …


The Diversity Of Terrestrial Mammals Surrounding Waterfall At Billy Barquedier National Park, Kelsey Johnson May 2019

The Diversity Of Terrestrial Mammals Surrounding Waterfall At Billy Barquedier National Park, Kelsey Johnson

Animal Science Undergraduate Honors Theses

Billy Barquedier is a National Park located in the Stann Creek district of Belize that contains Neotropical vegetation and wildlife. This study was performed in order to provide a baseline inventory and appearance frequency patterns of the terrestrial mammals located within Zone 1 of the park near a waterfall. The goal of the data and information collected during this study is to gain a greater understanding of the biodiversity and activity patterns of terrestrial mammals within the park and across Belize as a whole. The use of camera traps, small Sherman live traps, large live traps, and tracking methods were …


Evaluation Of Enzyme Effectiveness At Enhancing Fiber Digestion In Small Ruminants, Rachel Ranells May 2019

Evaluation Of Enzyme Effectiveness At Enhancing Fiber Digestion In Small Ruminants, Rachel Ranells

Animal Science Undergraduate Honors Theses

Feed costs account for up to 70% of total production costs making it vital that livestock producers maximize feed efficiency in a cost-effective manner (Bach, 2012). Producers often utilize feed additives to optimize nutrient absorption and increase productivity (McGrath et al., 2018). This study was conducted to determine the effects of an enzyme supplement containing Aspergillus niger and Aspergillus oryzae on dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) intake and digestibility by lambs fed ad libitum diets of either alfalfa or bermudagrass hay. The study was set up in a 2 2 …
