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 […]

Seven hundred and twenty and six hundred chicks, males and females, from 22 to 42 and from 43 to 53 days old, respectively, fed a basal diet (3100 and 3210 kcal ME/kg and 19.6 and 18.6% CP) deficient in sodium (0.017%), supplemented with NaCl, corresponding to the levels of .077, .137, .197, .257 and .317% of total sodium were used to determine the sodium requirements for broilers during the growing and final phases. A completely randomized design, in a 5×2 […]
