Abstract The objective of this study was to evaluate bird responses to flavophospholipol at higher doses than those recommended by the Brazilian legislation. A trial was conducted with 900 male broilers divided into five doses of flavophospholipol: 0, 2, 4, 8 and 16 mg/kg. The performance evaluation was conducted weekly until 42 days of age. The evaluated parameters were: weight gain, feed conversion corrected for mortality, feed intake and mortality. At the end of experimental period, birds supplemented with growth promoter differed from the negative control for weight gain and feed conversion in the period from 1 to 42 days. Body weight gain and feed conversion were significantly higher for birds fed 16 mg/kg of flavophospholipol, compared with treatment without the growth promoter in the period from 1 to 21 days. In the accumulated period from 22 to 42 days, all doses were different for the negative control for feed conversion and body weight gain. The performance improvement was maximized at the dosage of 10.1 mg/kg for feed conversion ratio and 10.9 mg/kg for body weight gain by regression analysis. Flavomycin can be used as a growth promoter to improve feed conversion ratio and body weight gain in broilers from 1 to 42 days of age.
