The present investigation evaluated the quality of turkey meat produced in two production systems, according to the following parameters: water loss in cooking, drip water loss, texture (shear strength), pH, color, humidity, protein, ashes and lipids. A total of 200 turkey breast samples of 500 g, separated by a batch of 20 samples, from ten aviaries from Santa Catarina, Brazil, were used: five from breeding with a traditional ventilation system and five with a mechanical ventilation system. Samples were obtained after slaughter and frozen at -15°C for 30 days. The results were submitted to variance analysis and the Tukey test. Significant differences were found only in the analysis of drip water loss. The birds of the traditional ventilation system presented 14.26% loss of water drip, while those of the ventilation exhaust system presented a loss of 19.21%. There were no differences in the chemical composition of poultry meat in relation to the production systems.
