- Abstract
The experiment was conducted at Department of Animal Science, Federal University of Viçosa to evaluate the effect of adding probiotics on ileal digestibility in diets for broilers. Four hundred male chicks Cobb 500, between 21-31d of age, were distributed in a randomized complete block design with 10 treatments in a factorial 5 x 2 (No probiotic, with antibiotic and with different strains and concentrations of Bacillus subtilis; and two levels of metabolizable energy: Normal and -100 kcal), with 8 replicates of 5 birds each. In the first three weeks of life, with the goal of increasing the health challenge of the birds received twice a week, a solution of reused litter and water in the ratio of 25 g/l for 8 hours. The addition of growth promoters resulted in increased ileal digestibility of dry matter averaged 6.79 % (67.56 % vs 63.26 %) and increased digestibility of crude protein in 3.64 % (79.45 % vs 76.66 %) on diet without the additive. The addition of probiotics based on Bacillus subtilis or antibiotic bacitracin methylene or dissalicilato in the diets of broilers in terms of health challenge is efficient to improve the digestibility of dry matter and crude protein.
