The present research aims at evaluating the productive parameters of the EMBRAPA lineages and comparing them to two commercial breeds in the period of 1 to 56 days. The experiment was done in the National Center for Poultry and Swine Research, at EMBRAPA, located in Concordia, Santa Catarina, Brazil. The research was carried out from July 6, 2001 to Aug 30, 2001, in a 56-day-experiment. Each box had 1.65x1.75m. The initial population was of 40 animals per box (13.88 broilers m-2), separated by sex and lineage. Forty-eight boxes were used, being 12 of each lineage and 6 of each sex containing 1920 animals in total. The animals received diets formulated according to the NRC (1994). The following parameters were estimated: food consumption, average weight, daily average weight gain, feeding conversion, and productive efficiency index. The experimental outline was the Entirely Randomized one with factorial scheme (4x2), having no interaction with any of the factors studied. A variance analysis over the obtained data was performed and the Tukey test was used when the "F" was significant. It was concluded that the EMBRAPA lineages have good husbandry characteristics. Its performance was close to what it is indicated in the commercial broiler manual.
