ME—metabolic energy; DPPH—2,2-Diphenyl-1-picrylhydrazyl; FRAP—ferric-reducing antioxidant power. Groups: C—control; FRA—group receiving a diet based on the control diet, with 8% fermented rapeseed meal (FRSMb) in place of some of the soybean meal (SBM); FR—group receiving a diet based on the control diet, with 8% FRSMb in place of some of the SBM, but without enzyme additives, pro- and prebiotic additives, organic acids, or added zinc. * % difference in content of nutrients, minerals, and bioactive substances in experimental groups (FRA and FR) relative to control (C).
