ABSTRACT

The aim of this study was to evaluate three flour blends of leaves plants aromatic replacing to antibiotic growth promoters on diet, over performance of broiler. Were used 280 male chickens of Ross 308 Genetic line of one until 42 days of aged distributed in a completely randomized design with four treatments and seven repetitions with 10 bird each one. The blends were in proportion perceptual of 50:50 of Origanum vulgare and Piper auritum (OHS), O. vulgare and Ocimum (OA), O. basilicum and P. auritum (HAS) flour, and flavomicin at 4 % like control group. The body weight was higher in the control group (2385 ± 69.88 g), consumption g/ave/día (204 g) and accumulates mortality (21.87± 3.60 %) that to other treatments to end of trial (P‹0.05); However, not difference (P›0.05) were found among OA (2198 ± 62.83 g) and HSA (2023 ± 40.12 g) respect to body weight and feed consumption. OA was lower at feed convertion (1.96±0.11) and OHS was higher (2.44±0.18). Were not differences found (P›0.05) on edible meat yield. Were concluded that blend of 50:50 of O. vulgare and O. basilicum include at 0.07% on diet of broiler is an alternative to replacement antibiotic growth promoters, lograting with that innocuous product to human consumption.
