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 …


Feed Formulation: Expanding Our Horizons Beyond The Simple Provision Of Least-Cost Diets, Rick Kleyn, Mariana Ciacciariello Sep 2023

Feed Formulation: Expanding Our Horizons Beyond The Simple Provision Of Least-Cost Diets, Rick Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Commercial feed formulation is typically based on linear programming (LP) algorithms that derive a least-cost solution for a blend of ingredients that meet specific nutrient criteria. This methodology has been effectively used for decades, but how we achieve our primary goal, which is sustainable poultry production, needs to be reconsidered in broader terms. Some of the issues that this paper will deal with are: not all parameters that we consider are linear and additive; we are still unsure of how to build the matrix required for feed formulation; dealing with the variability encountered in every batch of ingredient remains a …

No Antibiotic Ever (Nae) Versus Conventional Broiler Production: It’S Complicated, Marcos H. Rostagno Sep 2023

No Antibiotic Ever (Nae) Versus Conventional Broiler Production: It’S Complicated, Marcos H. Rostagno

Proceedings of the Arkansas Nutrition Conference

Broiler production has evolved significantly over the years to meet a constant growing demand for animal protein. Rooted on major advances in genetics, facilities and environmental conditions, management, and specially, in nutrition and health, the U.S. broiler industry improved tremendously in productivity and efficiency, clearly demonstrated by a marked reduction of the average market age (i.e., days to market), while significantly increasing average market weight, breast meat yield and feed efficiency (National Chicken Council, 2023). For decades, conventional broiler production was dominant, with extensive use of antibiotics to promote growth and manage disease challenges (prevention and control). However, concerns over …


Organic Trace Minerals In Environmentally Sustainable Systems, Sergio L. Vieira, Julmar C. Feijó, André Favero Sep 2023

Organic Trace Minerals In Environmentally Sustainable Systems, Sergio L. Vieira, Julmar C. Feijó, André Favero

Proceedings of the Arkansas Nutrition Conference

Essential trace minerals (Zn, Cu, Fe, Mn, Se and I) are traditionally included as supplements through mineral premixes in poultry feeds. In comparison to other essential nutrients, as well as energy, they are scarcely studied. The essentiality of a nutrient, by definition, refers to the nutrient role in normal body function, such as growth or egg production, and considers that they cannot be synthesized by the body and, therefore, must be supplied from the feed.


Application Of New Molecular Tools To Assess Virus Viability In Production Animals, Declan C. Schroeder Sep 2023

Application Of New Molecular Tools To Assess Virus Viability In Production Animals, Declan C. Schroeder

Proceedings of the Arkansas Nutrition Conference

Persistent viral infections routinely impose an inconvenient, always costly but thankfully not all too often catastrophic outcome on our modern food system. Managing viruses is key for all concerned if our objective is to meet the ever-growing demand to high-value animal protein. Whether it’s the impact influenza A virus (IAV) has on the avian or swine industries, Porcine reproductive and respiratory virus (PRRSV) on the swine or Deformed wing virus (DWV) on honey bees in both the honey and pollinator sectors - the negative impact and damaging cost to the individual producer, country and global economy cannot be overstated.

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

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 …

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington Jan 2023

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …

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, …
