dc.description.abstractThe 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 (weight gain, feed intake and feed conversion) and data from carcass characteristics (eviscerated carcass and commercial cuts) were evaluated. on day 42, six birds from each pen were sacrificed to determine digesta viscosity, and litter samples from each replicate pen were collected to determine litter moisture. The inclusion of 15% sunflower meal in broiler diets formulated on total amino acid basis worsens feed conversion ratio. Diets formulated on digestible amino acid basis are adequate when alternative feedstuffs, such as sunflower meal, are included. The use of sunflower meal in the diet does not influence carcass and cuts yields, but digesta viscosity increases when 15% of that feedstuff is included in the diet.en
