Abstract
Broiler Diet Formulation Has Been Based On Crude Protein Requirements For A Long Time Frequently Resulting In Diets Containing Amino Acid Levels Above The Suitable Requirements of Birds . Nevertheless The excess In Amino Acid Is Always Inefficiently Used By The Birds So That The Excess Is Dominated And Excreted As Uric Acid . Advances In The Knowledge About Amino Acid Requirements Protein Metabolism And The Possibility Of Production Economically Feasible Synthetic Amino Acids Increased The General Efficiency Of Protein Utilization . This In Turn Enabled The Nutrition To Diets Formulation Containing Amino Acid Levels More Appropriate To The Animal Needs Although Protein Levels Were Kept High . In Recent Years Many Studies have Directed Animal Nutritionists To Formulate Diets Based On The Ideal Protein Concept.
