Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon
Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon
Proceedings of the Arkansas Nutrition Conference
Poultry industry is rapidly moving towards utilizing the best ingredients to precisely feed the birds for better performance, welfare, health, and profitability. One of the practices that evolved over time with research is better optimization of amino acid utilization in the diets thus changing the crude protein landscape. Historically, if we compare the modern diets to diets from 1980, significant changes are visible in the use of unbound or crystalline amino acids leading to reduced levels of CP and reduced unutilized nitrogen in the diets. Multiple feed-grade amino acids are available in a cost-effective manner in poultry diets. Multiple research …

Effects Of Cyclic Heat Stress On The Acute Inflammatory Response In Broilers, Alessandro J. Rocchi, Chrysta N. Beck, Jossie M. Santamaria, Gisela F. Erf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Heat stress (HS) is a growing concern in broiler production. Little is known regarding the effect of HS on immune function. To examine the effects of HS on innate immunity, the local- and systemic-inflammatory responses to lipopolysaccharide (LPS) were examined in Cobb 500 male broiler chicks reared under thermoneutral (TN) or cyclic HS conditions. Beginning at four days of age, HS birds were subjected to 35 °C from 8:00 a.m. to 10:00 p.m. and TN temperatures from 10:00 p.m. to 8:00 a.m. At 37 days of age, four groups of broilers were formed: LPS-TN (8 broilers), phosphate-buffered saline (PBS)-TN (4 …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …
Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz
Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz
Poultry Science Undergraduate Honors Theses
Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale broiler production, with the intention of another honors student overseeing the implementation of the ideas set forth in the manual, in order to provide nourishment for the students and staff of a school in Belize. After determining that the …

Sustaining Competitiveness In Times Of Uncertainty And Volatility: A Latin American Perspective, Antonio Kalinowski
Sustaining Competitiveness In Times Of Uncertainty And Volatility: A Latin American Perspective, Antonio Kalinowski
Proceedings of the Arkansas Nutrition Conference
The poultry industry has dominated the dynamic livestock sector in Latin America during the last decades, doubling production in the last 20 years (Williams and Anderson, 2019). In the future, poultry production in the region is expected to grow at almost twice the annual global rate: 2.5% and 4.0%, respectively. The rapid expansion of the industry has been fueled by the growing consumer demand for chicken meat and eggs, given its price competitiveness and culinary preference in most Latin American countries. Per capita chicken consumption is among the highest in the world (on average ca. 30 kg/person/year), and represents above …
Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley
Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
While price typically drives consumers’ food-purchasing decisions in low-income countries, religious attributes associated with food production and corporate branding could influence buying patterns. In Mozambique, more than 46% of people were living below the poverty line of ($0.31 USD) per day in 2018. That being said, in the Nampula Province (the location of this study), which is the second poorest province in the country, over 25% of the population is Muslim and may be willing-to-pay (WTP) a premium for Halal meat products to uphold Islamic beliefs. Like many parts of sub-Saharan Africa, poultry is the fastest-growing source of protein. Since …
Effects Of Dietary Copper, Zinc And Manganese Source And Level On The Acute Inflammatory Response Of Broilers, Chelsea Ellington
Effects Of Dietary Copper, Zinc And Manganese Source And Level On The Acute Inflammatory Response Of Broilers, Chelsea Ellington
Graduate Theses and Dissertations
Trace minerals, particularly copper, zinc and manganese, play a role in ensuring optimal immune function. To examine the effects of diets containing different levels and sources of trace minerals on the inflammatory response, Cobb 500 broilers were fed four experimental diets containing 5 mg/kg Cu and 45 mg/kg of Zn and Mn or 10 mg/kg Cu and 90 mg/kg Zn and Mn in either the sulfate or hydroxychloride form. When the broilers were 5 weeks of age, 16 μg of lipopolysaccharide (LPS) was injected into the pulp of growing feathers (GF; 16 GF per chicken; 1 μg LPS per GF). …
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Graduate Theses and Dissertations
Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low …

Optimizing Gastrointestinal Integrity In Poultry: The Role Of Nutrients And Feed Additives, Sunday A. Adedokun, Opeyemi C. Olojede
Animal and Food Sciences Faculty Publications
Immunomodulation of the immune system by stimulating or suppressing one or both arms, is an emerging concept driven by the understanding of the host defense system. In particular, the gastrointestinal tract (GIT) functions not only as a site for digestion and absorption of nutrients but also acts as a metabolic and immunological organ. This serves as a barrier against abnormal presentation of luminal constituents, caused by dysfunctional intestinal epithelial barrier, to the mucosal immune system. Invasion by pathogens in the case of disease or stress or a massive influx of commensal bacteria overcomes the defensive mechanisms, resulting in the full …
