| Abstract | ||||
| In the present study100 samples collected from diarrheic and apparently healthy birds revealed a total of 3 bacterial isolates serologically typed as S. Typhimurium. Two hundred day old Ross chicks were divided into 8 groups (25 birds/pen): Gp 1 which contains the control negative, those of Gp 2 were administered L.acidophilus only, Gp 3 contains chicks that were administered S.cerevisiae, Gp 4 contains chicks that were administered E.faecium. Gp 5 contains chicks that were administered L.acidophilus plus S.cerevisiae, Gp 6 contains chicks that were administered L.acidophilus plus E.faecium, Gp7 contains chicks that were administered L.acidophilus, E.faecium and S.cerevisiae. While was keeping Gp 8 which contains the positive control.Oral challenge was performed using 0.2 ml suspension of 106 CFU of S.Typhimurium from 19 brs old nutrient broth culture on the third day of age. Results indicated that administration of L. acidophilus group plus E.faecium alone or with S.cerevisiae reduced the mortality rate to 8%. Our study pointed out that the usage of probiotics is of value in controlling of Salmonellae in chickens also usage of probiotic mixture from 2 or 3 is better. The application of L. acidophilus and E. faecium orally with or without S. cerevisiae in the feed reduced the mortality rate and shedding (table2) of Salmonella in chickens so it can replace antibiotic therapy in control of avian salmonellosis. | ||||
