Abstract :Effects of probiotics insert ignore into journalissuearticles values(Broilact, Bioplus 2B);, which are used as an alternative to antibiotics and chemical growth promoters, on broilers that were exposed to Salmonella typhimurium insert ignore into journalissuearticles values(S. typhimurium); lipopolysaccharide insert ignore into journalissuearticles values(LPS); were studied. For this purpose, 150 chicks for control group and 150 chicks for test group were used resulting in a total of 300 Ross line broiler chicks. Each of control insert ignore into journalissuearticles values(C); and test insert ignore into journalissuearticles values(T); group animals are further divided in to 3 subgroups as Check, Bro and Bio. Test subgroups insert ignore into journalissuearticles values(T­Check, T­Bro, T­Bio); received 3 ml of S. typhimurium LPS intraperitonally insert ignore into journalissuearticles values(IP);. T­Check animals received LPS only while T­Bro received Broilact, a commercial probiotic, via drinking water on day 1 after hatching only, and   T­Bio animals received Bioplus 2B, another commercial probiotic, via feed during the 42­day study period. Control subgroups were not exposed to LPS but C­Bro and C­Bio received probiotics same as the test subgroups insert ignore into journalissuearticles values(T­Check, T­Bro and T­Bio);. Effects of probiotics on the immune response of chickens against S. typhimurium LPS were followed by slide agglutination test using Salmonella `O` antigen.  Results indicated that percentage of Salmonella insert ignore into journalissuearticles values(+); animals increased in test subgroups after LPS exposure. No difference was found between Broilact and Bioplus 2B in regard to inhibiting Salmonella and supporting broiler`s health.
