This study evaluated a phytogenic feed additivefor broiler chickens. A total of 1,632 broiler chicks weredistributed into four treatments: negative control (withoutgrowth promoter); positive control (avilamycine, 10ppm +colistin, 15ppm); and two alternative treatments with 150ppmof phytogenic additive, one with a reduced Ca and P levels diet(PA-R1) and the other with lower energy, and amino acids,besides Ca and P (PA-R2). The trial was conducted with 12replicates, each consisted of a pen with 34 birds. The alternativediets showed body weight intermediate to the two controls at 42days, with no significant (P>0.05) treatment effect on feedconversion ratio. No treatment differences (P>0.05) on carcassyield and composition was observed. There was a tendency ofabdominal fat lipids saturation, when the phytogenic additivewas used, as possible consequence of a decreased level ofsoybean oil in the diets. A difference (P<0.001) on ingredientconsumption profile was observed between the treatments. Alltogether, this study showed a possibility to reduce the cost oftotal feed used to produce a broilers or a ton of body weight bythe utilization of the tested phytogenic additive.
