Effect of immersion and inoculation in ovo of Lactobacillus spp. in embryonated chicken eggs in the prevention of Salmonella Enteritidis after hatch

Abstract

It was evaluated the level of protection against Salmonella Enteritidis (3)in chickens after in ovo treatment with different species of Lactobacillus spp. inoculated into the air cell or by immersion in broth grown. Two hundred forty embryonated eggs were distributed into eight groups, corresponding to the following treatment with Lactobacillus acidophilus, L. fermentum, L. salivarius and control. On the 18th day of incubation, four groups were inoculated with 0.1 mL of inoculo in the air cell and four groups immersed for 3 minutes in culture of each treatment. Two days after hatched, it was inoculated 0.5 mL of culture of SE by intraesofagian means. On the fifth day of life, the chicks were euthanized and the ceca were processed to get the counting of SE. There was not a decrease in SE colonization of the ceca of chicks, regardless the treatment and means of administration. Samples of Lactobacillus spp. used in the treatment showed no potential probiotic for chicks when inoculated in ovo, in relation to the inhibiton of SE in the poultry ceca. Key words: Lactobacillus, Salmonella, embryonated egg, in ovo (AU)
