The objective of the research is to investigate effects of phytogenic additives as broiler feed supplements on production and slaughtering performances, morphological parameters and caecal microflora of fattening chickens of Ross 308 provenance. The research was based on two trials. In both trials, two feeding treatments were studied: a control diet with no supplemental feed additives (K) and a diet with a phytogenic additive supplemented to the control diet (1000g/t of Biomin PEP 1000, during the whole period). In the first trial, a total of 304 chickens were studied, in two treatments with four repetitions per pen with 38 chickens. The second trial included 16800 chickens, and it was conducted as a macro trial, that is, a pen with 8400 chickens was the subject of the trial. The results have shown that the chickens fed with the supplemental phytogenic additive have achieved significantly more favourable feed conversion rate. Differences in body mass and mortality rate between the trial group and the control were not statistically significant. Phytogenic additives did not have significant effects on breast portion and abdominal fat. Adding the phytogenic additive did not have significant effects on morphological parameters, but there was a tendency to increasing villous height and crypt depth. In both trials, the chicken groups fed with the supplemental phytogenic additive had less of all investigated groups of bacteria, and the differences were statistically significant for Enterobacteriaceae and Staphylococcus in the first, and Enterobacteriaceae and Enterococcus in the second trial. It can be concluded that the diet with the supplemental phytogenic additive had a positive effect on broiler performances, jejunum morphology parameters and caecal microflora.

| Abstract (Serbian): |
Cilj istraživanja je da se ispita uticaj fitogenog aditiva kao dodatka u ishrani brojlera, na proizvodne i klanične performanse, morfološke parametre i cekalnu mikrofloru tovnih pilića provenijence Ross 308. Ispitivanje je zasnovano na dva eksperimentalna ogleda. U oba ogleda ispitivana su dva tretmana ishrane: kontrolna hrana bez aditiva (K) i hrana za dodatkom fitogenog aditiva u osnovnu smešu (1000g/t Biomin PEP 1000, tokom celog oglednog perioda). U prvom ogledu ispitano je ukupno 304 pilića, prema dizajnu 2 tretmana sa 4 ponavljanja po boksu sa 38 pilića. U drugom ogledu ispitivanje je obuhvatilo 16800 pilića, a izvedeno po principu makroogleda, odnosno objekat od 8400 pilića bio je jedinica posmatranja. Rezultati su pokazali da su pilići hranjeni sa dodatkom fitogenog aditiva ostvarili signifikantno povoljniju konverziju hrane. Razlike u telesnoj masi i mortalitetu ogledne i kontrolne grupe nisu bile na nivou statističke značajnosti. Fitogeni aditivi nisu imali signifikantan uticaj na udeo grudi i abdominalne masti. Dodatak fitogenih aditiva nije rezultirao signifikantnim uticajem na morfološke parametre, ali je postojala tendencija povećanja visine resica i dubine kripti. U oba ogleda, grupe pilića sa dodatkom fitogenog aditiva imale su manji broj svih ispitivanih ciljnih bakterijskih grupa, a razlike su bile i na nivou statističke značajnosti za Enterobacteriaceae i Spaphylococcus u prvom i za Enterobacteriaceae i Enterococcus u drugom ogledu. Na osnovu dobijenih rezultata može se zaključiti da je ishrana sa dodatkom fitogenog aditiva indukovala pozitivan uticaj na performanse brojlera, morfološke parametre jejunuma i mikrofloru cekuma.
