Total phenolic content in breast meat of chickens fed with feed mixtures enriched with propolis and/or bee pollen

The aim of this study was to determine total phenolic (TP) content in breast meat of chickens fed with feed mixtures enriched with various amounts of propolis and/or bee pollen. This study was conducted on 200 Ross 308 chickens divided into five groups (control group i.e. group C fed with feed mixture and four experimental groups i.e. groups E1-E4 fed with feed mixtures supplemented with propolis and/or bee pollen, each supplement separately or in combination in a certain proportion). In breast meat samples the TP content was determined by the Folin-Ciocalteu method. Mean values of TP content (mg GE/g) in all groups were: 78.52±13.73 (C) ; 95.32±10.55 (E1) ; 87.42±16.84 (E2) ; 92.94±14.67 (E3) ; 88.56±9.82 (E4). The study showed statistically significant differences between group C and group E1 (p=0.007) and between group C and group E3 (p=0.020). It was concluded that addition of combination of propolis and bee pollen as well as addition of high concentration of propolis to feed mixtures enabled the largest incorporation of phenolic compounds in chicken breast meat. Such innovative technological solution in broilers feeding enables the production of healthier meat that can be considered functional food.
