The aim of this study was to examine alternative substances which could have the capability to replace antimicrobial growth promoters in feed for broilers. The 42-day long trial was performed on 100 days-old Arbor Acres broilers divided into two groups. Both groups of broilers were offerred a commercial feed mixture, while Paciflor C.10 ® (Hoechst - Intervet) was added in the amount of 0,10 and 0,05 kg/t of starter and finisher feed for the second group. Paciflor ® contains Bacillus cereus IP 5832 in the amount of 1010 CFU/g. Broilers of the control group had an average daily gain (ADG) of 48,86±6,80 g and a feed:gain ratio (FGR) of 2,17 kg with carcass yield of 72,2 %. The inclusion of direct-fed microbials (DFM) significantly increased ADG by 1,59 % and imporoved FGR and carcass yield by 1,84 and 0,42 % respectively. It is interesting to underline that supplementing the diet with DFM had only mild positive effects on ADG in the first two phases while a stronger influence was expressed on FGR. Better efficiency is probably due not only to the healthier composition of gut microflora, but to longer microvilli of the gut epithelium with consequently improved resorption of nutrients. The obtained results suggest that direct-fed microbials have the potential to replace, at least to a certaint antibiotics as feed additives.
