IntroductionOver the years, nutritionists have studied several ways to determine the ideal dietary supply of essential amino acids to optimize poultry performance. However, considering only performance objectives without taking into account economic factors may not reflect maximum profitability, since optimizing performance is not always viable (Pack et al., 2003). An economic approach to determin ...

@E. Ernest M. Pierson I applaud and agree that you formulate diet on analysed amino acid content rather than on table values. I like to add that technologies are available to have very immediate results on raw mateial quality including amino acids proximates and even heat damage of protein and amino acids. With AMINONIR by Evonik you get the result within minutes.As hopefully everybody agrees, cru ...

I. INTRODUCTIONLow-protein diets for broiler chickens axiomatically contain high inclusions of supplemental amino acids and have the potential to generate economic, environmental and bird welfare advantages. Low-protein diets are usually formulated by reducing soybean meal inclusions and increasing inclusions of a range of supplemental amino acids. An alternative approach was adopted in the presen ...

1. IntroductionThere is considerable interest in the successful development of low protein diets for broiler chickens, which axiomatically contain high inclusions of supplemental amino acids. This is because low protein diets have the potential to generate economic, environmental and bird welfare advantages.Formulation of low protein diets are usually achieved by decreasing soybean meal inclusions ...

Recent publications by Verhelle und Saremi (2024) and Westreicher-Kristen et al. (2025) reported broiler feeding experiments to evaluate the nutritional value of guanidinoacetic acid (GAA) in comparison to L-arginine (L-Arg). Basically, reported broiler performance responses are in agreement with expectations based on literature. However, the authors drew misleading conclusions on the efficacy of ...
