An experimental study was conducted to examine slaughter characteristics of broilers as dependent on the fattening period and rearing system employed. Fattening included extensive fattening in a poultry house and free-range rearing. Fattening lasted 49, 56 and 63 days. At the end of each of the above fattening periods, the randomly selected broilers were slaughtered for quantitative and qualitative traits of processed carcasses. This study presents the results on the proportion of certain (1st, 2nd and 3rd) meat categories in processed broiler carcasses. In terms of the effect of rearing systems analyzed and the gender of the examined broilers, the differences in the proportion of the first-category meat were small and statistically non-significant. Somewhat langer but equally non-significant differences were exhibited in terms of the fattening period, the highest and the lowest proportion of the first-category meat being produced by broilers aged 49 and 56 days, respectively. Similar results were reported on the proportion of the second- and the third-category meat for the examined broilers.
