Two experiments were conducted to evaluate the performance, development of digestives organs and recovered of Salmonella Enteritidis in chicks of different genetics lineages inoculated with probiotic using the technique of in ovo injection. The challenge with Salmonella spp and the feed fasting were promoted in chick s moments after the hatch. The birds ISA Label, Hubbard and Cobb were used in the experiments and the probiotic inoculated was based in multiple microorganism s culture. The experiments were designing in experimental random blocks with factorial arrangement 2x2x2 (probiotic X salmonella challenge X genetic lines). In both experiments the eggs were inoculated by in ovo injection at 19 days of incubation with probiotic and challenged with Salmonella Enteritidis in first day of age. In second experiment, the Cobb lineage birds were submitted to fasting of water and feed for 30 hours. The data were analyzed by variance analyses and Tukey test. The results showed that was no reduction of Salmonella colonization in digestive tract of chicks inoculated with probiotic. The inoculation of probiotic did not improve the performance of the chicks. Lower index of Salmonella were observed in older birds. In second experiment the fasting affected negatively the performance of the birds and the birds submitted to fasting were more susceptible to Salmonella Enteritidis
