Effects of Enterocin M and Durancin ED26E/7 substances applied in drinking water on the selected carcass characteristics and meat quality of broiler rabbits.

Bacteriocins represent substances of proteinaceous character with antimicrobial spectrum. This in vivo study was designed to reveal whether antimicrobial effect of Enterocin M (produced by non-rabbit origin strain Enteroccocus faecium AL41-CCM8558), in combination with Durancin ED26E/7 substances (produced by non-rabbit origin strain Enteroccocus durans ED26E/7) is able to influence the meat quality of rabbits. A total of 80 post-weaned rabbits, meat line P91 and M91 (aged 35 days, both sexes), were randomly divided into 4 groups (20 animals in each group). Control group without enterocin administration and experimental groups: EG 2 received 50pl of Enterocin M, EG 3 with 50|il Durancin and EG 4 with combination both of substances (50pl of Enterocin M + 50 |il of Durancin/animal/day) water administration for 21 days. Four animals (at the age 21 and 42 days) from each group were slaughtered No clinically noticeable changes in the average body weight of experimental animals were observed. A positive influence of Enterocin M and Durancin was noted on animal health. Enterocin M and Durancin substances did not negatively influenced growth performance and meat quality of selected carcass characteristics and meat quality of broiler rabbits, in general.
