Salmoneloses are zoonoses cause by pathogenic salmonellas very common in products of infected birds. A experiment was made with the main aim to consider the need to search subsidy and perfectly for control and prevention systems in the growth of disease in public health. 780 chickens from Ross line are used, they were 31-day-old, and three treatments have been applied to 4 repetitions of 65 birds each. The animals of treatment one received the probiotic Mucosal starter culture and were inoculated with Salmonella enteritidis in 10(5) units group colony forms/ militer. The treatment two was considered positive control and the animal were inoculated with S. enteritidis the same way that treatment one. The animals of treatment three did not receive probiotics and nor inoculated with salmonella. Some parameters were analyzed such as weight, food conversion , production factor and the percent of the contamination by salmonellas. There were not differences to the zootechnical and microbiological parameters for everyone treatments analysed. The animals that received probiotic did not show more efficient when inoculated with S. enteritidis, but they presented best performance that status from Ross line used.
