ABSTRACT The objective of this study was to evaluate the inclusion of cell wall of Saccharomyces cerevisiae (CWSc) and piperine in broiler rations and their effects on performance, carcass traits, blood parameters, ileal microbiota and nutrient digestibility. A randomized block design with five treatments and six replicates of 10 birds was used, totaling 300 chickens. The treatments consisted of: control ration (CR); CR + avilamycin (10 mg / kg); CR + CWSc (2.0 g / kg); CR + piperine (60 mg / kg); and CR + CWSc (2.0 g / kg) + piperine (60 mg / kg). The use of isolated piperine resulted in greater weight gain from 9 to 40 days of age (2505g). The additives CWSc and piperine conjugates influenced the lower coliform count in the ceca (4.45 CFU / g) and caused significant alterations in the biochemical serum and hepatic renal profile. The treatments had no effect on the nutrient metabolizable coefficients or on the carcass traits. There was no positive synergistic effect of the combined use of CWSc and piperine on broiler performance. The cell wall of Saccharomyces cerevisiae and piperine are effective at guaranteeing productivity, intestinal microbiota dynamics and hematological parameters; and as zootechnical additives, especially in broiler feeds free of antimicrobial performance enhancers.
