Abstract
ABSTRACT This study evaluated the impact of dietary Saccharomyces boulardii and Saccharomyces cerevisiae on the immunity of birds vaccinated against Pasteurella multocida and Salmonella gallinarum. A total of 105 male Cobb 500 broilers were divided into four groups: T1 (vaccinated, no supplement, n = 30), T2 (vaccinated, S. boulardii supplement, n = 30), T3 (vaccinated, S. cerevisiae supplement, n = 30), and T4 (non-vaccinated, no supplement, n = 15). Chickens received a corn-soy diet with 1x107 CFU/g of S. boulardii or S. cerevisiae for 42 days. Immune response was assessed by indirect ELISA
