After showed its beneficial effects on chicken growth performance, a study was conducted to evaluate the effect of adding from birth and during the whole growth period, flavophospholipol and edible mushrooms powder on carcass characteristics, viscera weights and digestive tract measurements of male broiler chicken. A total of 300 one-dayold male broiler chicks were randomly distributed into 1 to 10 treatments with three replicates per treatment and 10 chicks per pen. The experiment consisted in a 2 x 5 factorial arrangement of treatments including five concentrations of mushrooms powder (0, 0.5, 1.0, 1.5 and 2.0 g/kg of diet) and the addition of 0.0 or 5.0 mg/kg of flavophospholipol from birth date to slaughter time at 42-d. Results show that the additions of dietary mushroom powder and flavophospholipol have a positive effect on weights of carcass parts with commercial importance as the breast and drumsticks. In contrast, there is no effect on wings weight. Regarding viscera weights, mushroom powder but not flavophospholipol or the interaction of both, affected the thymus, spleen, bursa of Fabricius and liver weights. Finally, despite weak statistically significant results on several measurements of the digestive tract, results show no effect of mushroom powder or the antibiotic addition on these variables.
