To investigate the influence of multi-probiotic, fermented ginseng byproduct and fermented sulfone on the performance, intestinal microflora and immunity of broiler, a five weeks trial was conducted with 340, 1-d-old $Ross{\times}Ross$ broiler. All broilers were divided into five different groups having 68 birds in each treatment, and they were assigned as control, antibiotic avilamycin (AB), multi-probiotic (MP), fermented sulfone (FS) and fermented ginseng byproduct (FGB). Each artificial or naturally derived probiotic was inoculated 0.1% level with the basal diet, and all diets were provided to birds for five weeks. Weight gain and feed intake were measured weekly basis, and blood, spleen and feces were collectedand used for the physiological properties of broiler chickens. All performances and cholesterol profiles were not significantly differed but numerically lower level of neutral fat and LDL was found in multi-probiotics and FGB treatments respectively. The salmonella spp and E. coli numbers in the ileum were high in control in relation to those of other treatments and were significantly decreased in antibiotics treatments (p<0.05). In addition, Lactobacillus spp. showed significantly higher proliferation in MP as compared to that of others (p<0.05). Fecal ammonia and $CO_2$ gas emission was significantly decreased in MP, FGB and FS, respectively (p<0.05), but significantly increased proliferation of spleen was determined in MP group in comparison of other treatments (p<0.05). Therefore, the results indicates that multi-probiotics would be valuable feed additives to improve the salmonella, E. coli and Lactobacillus proliferation, and manure gas emission of broiler chickens, but further study related to the production of manure gas emission of MP is necessary.

This study was undertaken to investigate the influence of multi-probiotics, fermented ginseng byproducts and fermented sulfone as an alternative to probiotics on performance, intestinal microflora and immunity of broiler. A five weeks trial was conducted with one day old Ross${\times}$Ross broilers (n=340), divided into five groups which further divided into 4 replicates with 17 birds in each replicate. Birds were assigned to 5 dietary treatments as control, antibiotic avilamycin (AB), multi-probiotics (MP), fermented sulfone (FS) and fermented ginseng byproducts (FGB). Growth parameters were recorded on weekly basis while rest of the parameters viz. blood and faeces were collected at the end of the experiment. Growth parameters were not affected statistically by dietary treatments. However, numerically, higher body weight, splenocytes proliferation and lower total cholesterol and LDL values were found in MP treatment (P>0.05). Salmonella spp. count ($P{\leq}0.001$) and E. coli (P<0.001) concentrations in the ileum were found lowest in AB treatment while FS group showed lowest level of yeast (P<0.10) and Lactobacillus spp. ($P{\leq}0.001$). Fecal ammonia and $CO_2$ emission was significantly decreased in FGB than other dietary treatments (P<0.05). It was concluded that multi-probiotics would be valuable feed additives to improve the growth performance, Lactobacillus proliferation and immunity of broiler chicks.
