Stage Of Estrous Cycle Influences Behavior After Social Stress, 2021 University of South Dakota
Stage Of Estrous Cycle Influences Behavior After Social Stress, Alexander Jonah Rodriguez
Since women are almost twice as likely to develop major depression compared to men, research into this and other potentially debilitating mood disorders using behavioral studies should involve females despite hormonal, physiological, and potential behavior changes due to reproductive cyclicity. Until recently, most studies exclusively used males, thus limiting results of previous research to half of the population. Using adult female C57BL/6N mice as model organisms, we exposed them to novel forms of social stress across five days which encompassed the four-day estrous cycle to determine if the stages of the estrous cycle had an impact on behavior when ...
Terrestrial Soldier Crab (Coenobita Clypeatus, Fabricius 1787) And Cerion Spp. (Röding 1798) Shell Relationship On San Salvador Island, Bahamas, Harley Hunt
The Caribbean terrestrial soldier crab, Coenobita clypeatus(Fabricius 1787), coexist and utilize the shells of numerous species of land and marine gastropods. Soldier crabs rely on gastropod shells for protection as the crabs have a soft abdomen, leaving them vulnerable for predation and desiccation, threatening their survival. This creates a strong pressure to obtain well-fitting shells that provide adequate protection against water loss. Cerion of Röding (1798) shells are one of the most commonly used shells among living colonies of C. clypeatuson San Salvador Island. This study is interested in the frequency of shell use by C. clypeatus crabs ...

Not All Pollinator Gardens Are Created Equally: Determining Factors Pertinent To Improving Pollinator Garden Effectiveness, Travis Watson
Electronic Theses and Dissertations
Increasing evidence documenting the decline of insect populations, resulting from increasing human disturbances has resulted in efforts to establish pollinator gardens to provide additional resources for insect populations. However, our understanding of biotic and abiotic garden characteristics important for attracting and sustaining pollinator diversity is limited. Here, we evaluated 17 pollinator gardens to evaluate the effect of five biotic and three abiotic garden characteristics on pollinator species richness, abundance, and proportional representation of four pollinator functional groups. Plant species richness positively influenced pollinator richness and negatively influenced flower visitation. Bombus proportional abundance responded to several variables (distance to vegetation, plant ...

The Effects Of Common Stressors On Poultry Production: A Case Study In Northern Mozambique, Grace Lehfeldt
Finance Undergraduate Honors Theses
Chicken is one of the main proteins that feeds the world. For centuries, the human race has relied on chickens to eat. Therefore, as food science becomes more relevant, the way that chickens are raised has become a science. However, this is not true in every part of the world. In Mozambique the process for raising chickens for consumption is not the same as it would be in America. This is a study of two specific “stressors” (feed and temperature) and how they impacted chicken growth and development on a live production poultry farm in Northern Mozambique. In addition, it ...

Animal Science Undergraduate Honors Theses
Having and maintaining good leadership skills should be an important way of life for most college students. As these individuals search for their first jobs and employment outside of the university experience, many businesses and employers will utilize these leadership traits and officer positions within specific clubs and organizations to select who to extend a job offer. Many student associations which place their focus on animals, both agriculturally raised livestock and companion animals, take pride in the skills and proficiencies they teach their members. This study utilized a survey of both multiple choice and Likert Scale styled questions in order ...
The Effects Of Trace Mineral Supplementation On Performance, Health, And Carcass Quality Of At-Risk Mineral Deficient Feedlot Cattle, Tevan J. Brady
All Graduate Theses and Dissertations
Morbidity in feedlot cattle due to disease is a common economical loss for feedlot producers. Utah is not typically considered a ‘feedlot state’, but there are several producers in the southern part of the state that specialize in receiving at-risk cattle. These cattle are at-risk because they are coming from areas known to be mineral deficient. Areas such as the western US, are known to be deficient in several trace minerals important in immune response. Therefore, it is critical that producers have an adequate plan to decrease the negative effects that this has on economic viability of their beef operations ...
Investigation Of Methionine And Lysine Derivatives As A Source Of Rumen-Protected Amino Acids For Lactating Dairy Cows, Mark Avila Fagundes
All Graduate Theses and Dissertations
Cows have a protein requirement for growth, maintenance, and lactation. In order to meet those protein requirements, dairy farmers can supplement or feed cattle with specific amino acids, the building blocks that make-up protein. However, in order for the amino acid product to be effective it must avoid degradation in the rumen and be delivered in the small intestine for absorption. Lysine and methionine have traditionally been recognized as the most limiting amino acids for lactating dairy cows. Therefore, nutrition companies have focused on finding ways to encapsulate or protect lysine and methionine from rumen microbes. The N-acetyl-L-methionine and N-acetyl-L-lysine ...
