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 …
Feed Formulation: Expanding Our Horizons Beyond The Simple Provision Of Least-Cost Diets, Rick Kleyn, Mariana Ciacciariello
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 …
Reducing Feed’S Environmental Footprint: Where Are The Opportunities?, Lara Moody
Reducing Feed’S Environmental Footprint: Where Are The Opportunities?, Lara Moody
Proceedings of the Arkansas Nutrition Conference
Working with animal food industry members and stakeholders up- and down-stream in the supply chain, the Institute for Feed Education and Research (IFEEDER) developed a ‘Sustainability Road Map’ to support the U.S. animal food industry as it pursues continuous improvement on impacts important to industry members and their customers. For IFEEDER and the American Feed Industry Association (AFIA), sustainability is defined and managed by each individual organization to deliver measurable, continuous improvements on the impacts related to people, planet and governance that are most important to them and their stakeholders.
No Antibiotic Ever (Nae) Versus Conventional Broiler Production: It’S Complicated, Marcos H. Rostagno
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
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
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.
A View Of Poultry Production In The Americas, Michael Donohue
A View Of Poultry Production In The Americas, Michael Donohue
Proceedings of the Arkansas Nutrition Conference
The primary goal of the presentation is to share a long-term overview of how broiler production has changed over the last 35 years in areas of bird performance, production costs, particularly in the area of feed ingredient cost per lb. and illustrating how poultry nutritionists have adapted feed formulations to meet the changes in performance and cost.
Effect Of Authentic Kefir And Nigella Sativa On Broilers Challenged By Coccidia And Clostridium Perfringens, Julian E. Nixon
Effect Of Authentic Kefir And Nigella Sativa On Broilers Challenged By Coccidia And Clostridium Perfringens, Julian E. Nixon
All Dissertations
Black seed oil concentrations of 0%, 0.1%, 1% and 5% were added to milk inoculated with kefir grains and incubated at 25°C for 22 h. The pH and microbial count indicated 1% black seed oil caused low inhibition (P > 0.05) of fermentation, but 5% black seed oil caused significant inhibition of the kefir microorganisms (P < 0.05).
Cobb 500 male chicks (n = 256) were distributed in a randomized block design and received one of four treatments: CTRL1 (Non-medicated, no kefir, no Clostridium perfringens), CTRL2 (Non-medicated, no kefir, C. perfringens inoculated), CTRL3 (BMD medicated, no kefir, C. perfringens inoculated), KTRT (Non-medicated, …
