The aim of this study was to evaluate the effect of the inclusion of a phytobiotic composed of essential oil of Rosmarinus officinalis, herbal choline, Cynara scolymus meal and Silybum marianum on the productive parameters and the drip losses of the carcass of broilers raised in the humid tropics. In total, 4800 male Ross AP chickens were used, housed in 10 open poultry shed and at ambient temperature (27-37 °C). The birds were distributed in a completely random model composed of five repetitions and two treatments: (D1) control diet with commercial base feed, (D2) commercial base feed with the inclusion of the phytobiotic at 400 g/t. The experimental period lasted 42 days and weight gain, feed intake, feed conversion rate and productivity index were determined. For the evaluation of meat quality, drip losses and malondialdehyde production were measured. On day 42, the animals that consumed the phytobiotic presented a better feed conversion rate and higher productivity index (1.50 and 96.78 respectively), compared to the control group (1.60 and 81.33 respectively). Regarding meat quality, the animals supplemented with the phytobiotic had lower drip losses. In conclusion, animals raised in the humid tropics supplemented with phytobiotics showed better efficiency in the production process.
