The objective of the present experiment was to evaluate the inclusion of sunflower meal in diets formulated on total or digestible amino acid basis fed to broilers of 22 to 42 days of age. Nine hundred and sixty birds were distributed in a completely randomized experimental design in a 2 × 2 factorial arrangement (two formulation criteria – digestible or total amino acids; two sunflower meal inclusion levels – 0 or 15%), with six replicates of 40 broilers each. Performance […]

Com o objetivo de determinar as exigências de sódio para frangos de corte durante as fases de crescimento e final, foram utilizados, respectivamente, 720 e 600 frangos, machos e fêmeas, nos períodos de 22 a 42 e de 43 a 53 dias de idade, submetidos a uma dieta basal (3.100 e 3.210 kcal EM/kg e 19,6 e 18,6% de PB) deficiente em sódio (0,017%), suplementada com NaCl, correspondente aos níveis 0,077; 0,137; 0,197; 0,257 e 0,317% de sódio total.
