Combination of Bacillus licheniformis and Salinomycin: Effect on the Growth Performance and GIT Microbial Populations of Broiler Chickens

The aim of the study was to investigate the effect of and salinomycin supplementation in broiler diets as individual factors or in combination on the growth performance, GIT morphometry, and microbiota populations. Four hundred one-day-old Ross 308 chicks were randomly distributed to four dietary tr...

Description
Summary:The aim of the study was to investigate the effect of and salinomycin supplementation in broiler diets as individual factors or in combination on the growth performance, GIT morphometry, and microbiota populations. Four hundred one-day-old Ross 308 chicks were randomly distributed to four dietary treatments (10 replicates, 10 birds each). The following treatments were applied: NC-no additives; NC + SAL-salinomycin addition (60 mg/kg diet), NC + PRO- DSM 28710 preparation (1.6 × 10 CFU/kg; 500 mg/kg diet), and NC + SAL + PRO-combination of salinomycin and . Probiotic administration resulted in improvement ( < 0.05) of the performance parameters, including body weight gain (1-10 d, and 11-22 d) and feed conversion ratio (11-22 d, 1-36 d). An interaction ( < 0.05) between experimental factors was observed in terms of lower pH values in the crop (tendency, = 0.053) and ceca. Both factors lowered the alpha diversity and Enterobacteriaceae and promoted Bacillaceae communities in the jejunum ( < 0.05). Interactions were also observed in terms of reducing Clostridiaceae in the ceca. In conclusion, the combined use of and salinomycin in broilers' diets had beneficial effects.
