RESUMO
The influence of alternative treatments using fluidextracts of Alternanthera brasiliana, propolis resin and linseed oil on the performance and blood biochemistry of broilers was evaluated. The study was done with five treatments: basal diet (negative control); basal diet + 40 ppm avylamicin and 120 ppm monensin (positive control); basal diet + A. brasiliana extract (180 mL/200 kg of feed); basal diet + propolis extract (200 mL/200 kg of feed) and basal diet + linseed oil (2.5% replacing soybean oil). Propolis and A. brasiliana extracts improved broiler performance from 14 to 21 days, whereas linseed oil had no effect. The findings of this experiment revealed that A. brasiliana and propolis extracts can be used as antimicrobials, but further studies are necessary to find the best concentration in broiler diets.
