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.
Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady
Ireland V. United States: Agricultural And Environmental Sustainability Policies, Lauryn O'Grady
Accounting Undergraduate Honors Theses
The United States and Ireland have varying practices to achieve similar objectives in regard to environmental sustainability. While the European Union has maintained and updated a uniform policy throughout its existence--the Common Agricultural Policy--the United States instead created short-term solutions to a long-term problem. Not only does the United States tend to solve issues in the short-term, the policies between agricultural production and environmental sustainability are not necessarily aligned or remotely relative to the other. While the United States’ new Global Food Security Strategy implements parts of both agricultural and environmental sustainability, much of the history was not based off …
