The aim of the work was to study the curative-prophylactic efficiency of the complex biologically active microbial preparation and its effect on some growth and development indicators of chickens. The preparation was included in a proportion of 40 g/kg feed, in the composition of the daily ration of the chickens in the experimental group, starting from the first day of life. At the age of 17 days, an infection with Clostridium perfringens was registered in the chickens from both groups, which was treated with the Bromex preparation. As a result of the daily administration in the ration of the complex biologically active microbial preparation, the viability of 100% of the chickens in the experimental group was ensured compared to 72% in the control group; decreasing the titer of pathogenic bacteria E. coli, Enterococcus spp., Clostridium spp. by 6.5-10.6%, in the gastrointestinal tract; increasing the titer of beneficial microorganisms Bifidobacterium spp., Bacillus spp. and yeast fungi by 3.6-15.4%; the increase in the body weight of the chickens at the end of the experiment by 25.5% compared to the control.
