The present study investigates the effects of Enterococcus durans ED26E/7 beneficial strain and its enterocin – durancin (Ent) ED26E/7 on selected parameters in rabbits: growth performance, caecal enzymatic activity, jejunal morphometry and meat physico-chemical characteristics. Seventytwo rabbits (aged five weeks, M91 meat line, both sexes) were divided into experimental groups E1 (E. durans ED26E/7 strain; dose 500 μL/animal/day, concentration 109 CFU/mL) and E2 (durancin EntED26E/7; dose 50 μL/animal/day, with activity 12 800 AU/mL) and control group (C). The additives were administered in drinking water for a period of 21 days. All animals remained in good health during the experiment. The highest body weight gain (increase by 1.5% compared to C) was noted in E1 group during ED26E/7 strain application (P<0.001). Both bioactive compounds positively influenced (reduced) the feed conversion ratio (P<0.001). The ED26E/7 strain and its EntED26E/7 application stimulated the activity of most enzymes tested in the caecum; only the amylolytic and inulolytic activity in E2 group decreased during durancin ED26E/7 addition. Both additives, but mainly the ED26E/7 strain, showed a tendency to improve the jejunal morhological parameters till the end of the experiment (day 42). The meat physico-chemical parameters were not negatively influenced by the application of E. durans ED26E/7 strain and its durancin ED26E/7. The diet supplementation with bacteriocinogenic and probiotic E. durans ED26E/7 strain and its EntED26E/7 may improve the growth performance, caecal enzymatic activity and jejunal morphometry of rabbits, without any negative effect on rabbit meat quality.
