Abstract:

The efficacy of a Competitive Exclusion (CE) culture, inulin, combination of CE culture and inulin and flavophospholipol in controlling Salmonella colonization in broiler chicks was studied. Experimental chicks were challenged with 10 CFU of Salmonella typhimurium /chick on day 3 and sacrificed on day 21. Log CFU Salmonella and lactic acid bacteria (LAB) counts/g of cecal contents were assessed. Sections from the ceca samples were subjected to histopathological evaluation. The mean of Salmonella counts in the cecal contents of challenged birds in the various experimental treatment groups were significantly lower than the challenged control group which had a count of 6.13 log10 CFU/g. Counts obtained were 1.25 for the groups supplemented with flavophospholipol an antibiotic; 1.53 in the group treated with CE culture composed of Lactobacillus Acidophilus. L. plantarum and Lactococcus lactis; 2.05 in the group supplemented with 0.1% inulin, a prebiotic; and 1.75 in the group with combination of CE culture and inulin. These results show the efficacy of the CE Culture in controlling Salmonella colonization in the ceca of birds and PF values obtained also show its potential as an alternative to the use of antibiotics in broiler production.
