Animal welfare concerns remain a critical element of legislation and policy related to commercial livestock production. Pasteurized and free-range systems are increasingly becoming popular in broiler production. However, exposure to disease-causing organisms and foodborne pathogens in these environments remains a challenge. Therefore, probiotics can be used as commercial animal feed supplements in poultry diets.

In order to assess the effects of the probiotic additions on growth performance, intestinal microbiome, and caecal colonization of Salmonella in the poultry industry challenged with Salmonella enteritidis, a total of 9 commercial chicks were subjectively divided into three groups in the current study. The groups included C01: basal diet (negative control), C02: basal diet and challenged with Salmonella on 3rd day (positive control) and C03: received probiotic mix and then challenged with Salmonella. The gathered information demonstrated that the probiotics improved growth outcomes and decreased total Salmonella counts.
