Oxidative stability of breast meat from broilers fed diets supplemented with synbiotic and organic acids

The purpose of this study was to investigate the effect of synbiotic and organic acids on oxidative stability of breast broiler meat. The experiment consists on 120, 2 days old Ross 308 chicks, housed in metabolic cages (6 chicks/cage). A 2 x 2 factorial arrangement was considered with 4 treatments and 5 replicates (30 animals per group). Two different levels of synbiotic (0 and 10 g/kg) and two different levels of organic acids (0 and 1.5 g/kg) were added to the standard diets in order to constitute the four experimental diets. For further analysis, breast meat from 6 animals per group were collected in 42^nd experimental day. No significant differences were noticed for any oxidative parameter measured in breast samples except TBARS (significant decreased values for OA supplemented groups), at the end of experiment. After 4 days of refrigeration (4°C), the secondary oxidative products (panisidine, TBARS) were significant smaller for E groups, compared to C. After 7 days of refrigeration (4°C), the OA groups had significant smaller values for primary (CD) and secondary oxidation products. Synbiotic and organic acids supplements presented positive effect on meat quality by increasing oxidative stability of breast meat during storage.
