Effects Of Cyclic Heat Stress On The Acute Inflammatory Response In Broilers, Alessandro J. Rocchi May 2023

Effects Of Cyclic Heat Stress On The Acute Inflammatory Response In Broilers, Alessandro J. Rocchi

Poultry Science Undergraduate Honors Theses

Heat stress (HS) is a growing concern in broiler production due to increasing environmental temperatures. Little is known of the overall effect of HS on innate immunity. Lipopolysaccharide (LPS), an outer membrane component of Gram-negative bacteria, is commonly used to study the inflammatory response. In avian species, the local tissue and systemic inflammatory activities in response to LPS may be determined concurrently, over time, in an individual, using the growing feather (GF) pulp dermal test along with blood measurements (dual-window approach). To examine the effect of cyclic HS on the local and systemic acute inflammatory responses, Cobb 500 male broiler …

The Role And Implications Of Negotiation In Fed Cattle Transactions, Taralee Hudson May 2023

The Role And Implications Of Negotiation In Fed Cattle Transactions, Taralee Hudson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Within the past three decades, a significant evolution has occurred in how fed cattle are bought and sold. Driven by changes in the quality of beef and consumer health preferences, the beef industry began to advocate for “value-based marketing,” resulting in the development of grid pricing and eventually formula transactions. Alternative marketing arrangements (AMAs) have become the predominant method used for the sale of fed cattle, ultimately resulting in fewer transactions in the negotiated cash market. Such market conditions have recently reignited concerns among industry stakeholders about potentially uncompetitive outcomes for beef producers, particularly after the occurrence of sequential Black …

Inhibiting Survival Of Salmonella During Desiccation Through The Use Of Naturally Occurring Signals, Joseph Headrick May 2023

Inhibiting Survival Of Salmonella During Desiccation Through The Use Of Naturally Occurring Signals, Joseph Headrick

Electronic Theses and Dissertations

A rising problem in agriculture is the increase of antibiotic-resistant Salmonella cases associated with chicken eggs, which transmit infection to humans. To counter this, new approaches to combat Salmonella in chickens and desiccated on eggshells are vital in the prevention of human foodborne illness. Disrupting signaling pathways with naturally occurring compounds provides a potential novel avenue for prevention of Salmonella infections, as this would disrupt sensing of these environments and inhibit subsequent optimal gene expression. Starting with signals identified in previous studies, salicylic acid was found to inhibit Salmonella desiccation survival on both eggshells and plastic. To expand upon this, …

Approaches For Mitigating Woody Breast In Commercial Broilers Through Nutritional And Management Strategies, Clay Maynard May 2023

Approaches For Mitigating Woody Breast In Commercial Broilers Through Nutritional And Management Strategies, Clay Maynard

Graduate Theses and Dissertations

Breast myopathies have caused significant economic losses to the poultry industry over the last decade. The induction of woody breast (WB), white striping (WS), and spaghetti meat (SM) have caused textural issues, functional issues, and a decline in consumer acceptance. Of these three myopathies, WB causes the most pronounced effects on product quality and reduces functional use. Woody breast is also commonly associated with expansive breast meat growth/high performing broilers. However, progress in reducing these myopathies has been limited without hindering other aspects of poultry rearing. Generally, production performance reduces as myopathy occurrence or incidence reduces. This response is primarily …

Physiological, Temporal, And Environmental Determinants Of Forage Fish Caloric Content In The Gulf Of Mexico, Rebecca R. Walsh Apr 2023

Physiological, Temporal, And Environmental Determinants Of Forage Fish Caloric Content In The Gulf Of Mexico, Rebecca R. Walsh

Honors Theses

Within the Gulf of Mexico, forage fish species serve as an important link between lower trophic levels and higher trophic levels, supporting economically valuable predator fish, birds, and mammals. Despite the key ecological role of forage fish, fisheries management efforts are often directed elsewhere; as a result, input data for fisheries models is unavailable for many forage fish species. To fill this knowledge gap, we sought to produce species-specific caloric content values for four forage fish species in the Gulf of Mexico: Atlantic croaker (Micropogonias undulatus), white trout (Cynoscion arenarius), bay anchovy (Anchoa mitchilli), …
