Does Phytase Change How We Feed Breeders?, Wenting Li
Does Phytase Change How We Feed Breeders?, Wenting Li
Proceedings of the Arkansas Nutrition Conference
Dietary evaluation of the use of exogenous phytase has received considerable attention in broilers, but not broiler breeders. Moreover, the limited studies that have assessed phytase in broiler breeders are dated, which makes interpretation problematic because dated phytase enzymes are not as efficacious as current phytase enzymes. The article addressed practical applications for dietary phytase in broiler breeder diets.

Kinetics Of Protein And Amino Acids, S. Y. Liu, M. Toghyani, S. P. Macelline, P. H. Selle
Kinetics Of Protein And Amino Acids, S. Y. Liu, M. Toghyani, S. P. Macelline, P. H. Selle
Proceedings of the Arkansas Nutrition Conference
Protein and amino acid nutrition is key to poultry growth and sustainability, with synchrony between glucose and amino acid availability being critical for efficient feed conversion. While non-bound amino acids (NBAA) are rapidly absorbed and increasingly used to reduce crude protein levels, their fast uptake may disrupt amino acid balance and reduce nutrient utilization compared to protein-bound amino acids. Future research should redefine amino acid requirements in low-CP diets, explore the metabolic fate of NBAA, and investigate how protein sources affect gut microbiota and host metabolism.
Low Protein Diet Strategy, S. Y. Liu, P. V. Chrystal, M. T. Kidd, M. Toghyani, S. P. Macelline, P. H. Selle
Low Protein Diet Strategy, S. Y. Liu, P. V. Chrystal, M. T. Kidd, M. Toghyani, S. P. Macelline, P. H. Selle
Proceedings of the Arkansas Nutrition Conference
Reduced crude protein (CP) diets can lower nitrogen excretion and improve litter quality, but their effectiveness varies depending on the grain type, with wheat-based diets often showing poorer broiler performance compared to maize or sorghum. The digestive dynamics and synchrony between NBAA and protein-bound amino acids, along with starch-to-protein ratios, influence feed efficiency and fat deposition, which remains a challenge in reduced CP diets. Optimizing amino acid supplementation and exploring alternative protein-rich ingredients may help improve outcomes, especially in regions with limited access to soybean meal.
Shell Translucency: A Novel Eggshell Quality Parameter In Broiler Breeders, Duarte Neves, Austin Jasek, Colwayne Morris, Raquel Burin, Kevin Stephens, Marco Rebollo
Shell Translucency: A Novel Eggshell Quality Parameter In Broiler Breeders, Duarte Neves, Austin Jasek, Colwayne Morris, Raquel Burin, Kevin Stephens, Marco Rebollo
Proceedings of the Arkansas Nutrition Conference
In the United States, nearly 240 million commercial broiler breeder eggs are incubated weekly with an average hatchability of 79.1% (Third Party Reporting). Between 160 eggs/hen and 125 chicks/hen the loss is considerable. In 2007, an estimated 1% improvement in hatchability would escalate profits by over $25 million to hatcheries and markedly increase profitability in broiler operations (Schaal and Gherian, 2007). In order to tap into top hatchability performances, egg management in commercial hatcheries such as egg storage time and conditions, incubation temperature and humidity, as well as turning frequency are of utmost importance (Vick et al., 1993; Reis et …
Blend Feeding Broilers To Daily Nutrient Requirements, J.T. Pope
Blend Feeding Broilers To Daily Nutrient Requirements, J.T. Pope
Proceedings of the Arkansas Nutrition Conference
Broiler producers and nutritionists have used phase feeding as a practical means to define broiler feeding programs. Each feed phase has discreet nutrient definitions intended to be fed for a defined number of days based on a feed mass delivered per broiler. A typical broiler feeding program would consist of three to five feed phases over the production cycle that intend to address the changing nutrient requirements as broilers age. Phase feeding programs are easily defined, practical to manage, and provide a predictable cost structure for broiler producers. Despite the practicality of phase feeding, there are inherent flaws that will …

Importance Of A Rooster Feed In Broiler Breeder Production, Alex Corzo, Marcelo Silva
Importance Of A Rooster Feed In Broiler Breeder Production, Alex Corzo, Marcelo Silva
Proceedings of the Arkansas Nutrition Conference
Of all feed phases in poultry production, rooster feeding is arguably the least studied. During the rear phase, there is general agreement that male and female broiler breeders can be provided a common feed program, only differing on feed amounts provided, that results in growth targets reached for each sex. It is during the production phase that there is some disagreement on the best way to support the nutritional needs of the adult rooster. A considerable segment of the world does employ a rooster feed as a way to better support the nutritional needs of working males. Other poultry operations …

Every Day Feeding Of Broiler Breeder Pullets, David Brandt
Every Day Feeding Of Broiler Breeder Pullets, David Brandt
Proceedings of the Arkansas Nutrition Conference
Broiler breeders are characterized by their fast growth and sensitivity to light stimuli. Unlike commercial layers, they have a lower egg production rate and are kept on the floor during rearing and laying periods. Fertile eggs are the primary objective, necessitating careful management of their egg-laying properties, while controlling their body weights. Unrestricted feeding leads to early laying with poor peak and persistency in egg production. Therefore, nutrient intake must be restricted to achieve target body weights at light stimulation (22 weeks). This involves both quantitative and qualitative feed restrictions. Quantitative feed restriction can lead to issues such as poor …
Integration Of Commercial Broiler Data Into A Broiler Growth Model, David Brandt
Integration Of Commercial Broiler Data Into A Broiler Growth Model, David Brandt
Proceedings of the Arkansas Nutrition Conference
This study explores the alignment of theoretical broiler growth models with practical farm conditions, emphasizing the value of integrating commercial data into simulation models. The EFG Broiler Growth Model, developed by Emmens, Fisher and Gous, is highlighted for its mechanistic approach, predicting growth based on feed intake. While empirical models are useful, they are limited by changes in genetics. Both mechanistic and empirical models struggle to predict how broilers will respond to feed under the challenging conditions typically experienced in commercial operations. The study also discusses the development of empirical models to determine broiler responses to balanced protein and energy, …
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 …

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.
