Two experiments (Exp) were carried out to evaluate diets for broilers formulated with reducing crude protein (CP) level, supplemented with synthetic amino acids, formulated based on total amino acids (TAA) (Exp 1) or digestible AA (DAA) (Exp 2). The experiments conducted in the period from 3 to 6 weeks of age of the birds. In both experiments, the four levels of CP were: 20.8, 19.7, 18.6 and 17.5% CP. In the Experiment 2, two other treatments were added: diets containing […]
