Accurately meeting the dietary P needs of broilers is critical to ensure optimal bird performance, health, and welfare without causing undue environmental burdens associated with excess dietary P excretion. Phosphorus is commonly supplied in broiler diets from inorganic phosphates derived from non-renewable sources, but it has been estimated that peak P production will occur between 2030-2040 and that the global supply of P could be depleted within this century (Cordell and Drangert, 2009; Nest and Cordell, 2012). To address these concerns, inorganic P use in agriculture, including use in broiler diet formulation, requires careful stewardship. To this end, the dietary …

Amino Acids Were Not All Created Equal, Peter H. Selle, Shemil P. Macelline, Peter V. Chrystal, Sonia Y. Liu
Proceedings of the Arkansas Nutrition Conference
The contention that amino acids were not all created equal is based on the simple premise that intestinal uptakes of non-bound (synthetic, crystalline, feed-grade) amino acids are more rapid than their protein-bound counterparts. The post-enteral ramifications of this difference in bioequivalence are amplified in broiler chickens given their express growth rates and just one complication is the post-prandial oxidation of amino acids. The lack of bioequivalence between non-bound and protein-bound amino acids is a real obstacle to the development and adoption of reduced-crude protein diets that have the potential to promote sustainable chicken-meat production Thus, the purpose of this paper …
