Use of probiotics can be alternative to antibiotics which are added to food as growth stimulators. Investigation of the effect of probiotics and antibiotics was done on experimental farm ‘’Pustara’’, of the Faculty of Agriculture in Novi Sad. Trial consisted of three groups of chickens in five repetitions. First group was control, second group received probiotic in the water and food, and third group received antibiotic in food. Final body weight was (I) 2179 g, (II) 2190 g and in group (III) 2158 g. In first group, feed conversion was 1,93, mortality 4,27% and production index had value of 257, in second group 1,90, 3,47% mortality and PI 260. In third group, conversion was 1,93, mortality 2,40%, and PI value 265. Obtained results indicate positive effect of probiotic on production results, whereas, contrary to expectations the

A feeding trial was conducted to investigate the effects of dietary supplementations of synbiotic and probiotic on broiler performance, carcass yield, organs weights, and histomorphological measurements of small intestine. Six hundred 1-d-old broiler chicks were randomly assigned to 1 of 3 dietary treatments for 5 wk. The dietary treatments were 1) control, 2) basal diets supplemented with synbiotic (1 kg of Biomin IMBO/ ton of the starter diets and 0.5 kg/ton of the grower diets), 3) basal diets supplemented with probiotic (1 kg of a homofermentative and a heterofermentative Lactobacillus sp./ton of feed). The BW, average daily weight gain, carcass yield percentage, and feed conversion rate were significantly (P < 0.05) increased by the dietary inclusion of the synbiotic compared with the control and probiotic-fed broilers.

The current experiment was conducted to evaluate the effect of a synbiotic (Biomin Imbo) on intestinal microflora of Ross broiler chickens. A total of 200 male chickens were randomly divided into 20 groups of 10 birds each, kept in 20 pens (1.5 × 1 m each), and fed for 42 d at different synbiotic levels. Treatments included (1) a basal diet without synbiotics (control), (2) a basal diet with synbiotic levels proposed by the manufacturer, (3) a basal diet with synbiotic levels 25% lower than those proposed by the manufacturer, (4) a basal diet with synbiotic levels 50% higher than those proposed by the manufacturer, and (5) a basal diet with synbiotic levels 25% higher than those proposed by the manufacturer. At the end of the 42-d feeding period, 1 bird was randomly selected from each experimental unit, humanely euthanized,
