Effect of barbatimão verdadeiro (Stryphnodendron adstringens Mart.) on the performance and control in broiler eimeriosis

The major health problems affecting industrial production of broilers is avian eimeriosis. An effective control of this illness has become indispensable and mostly is accomplished to the addition of coccidiostats in feed. However it has been observed that this intensive practice most often is used incorrectly, resulting in problems of resistance and deposition of residues in meat, requiring searches for new alternatives to control avian eimeriosis. Therefore the objective of this study was to evaluate the effect of the peels from the barbatim?o verdadeiro (Stryphnodendron adstringens Mart.) on the performance of broilers and therapeutic activity in combat of eimeriosis control influenza. The 700 male Cobb500 one day age broilers were used and randomly divided into five treatments with four replications. The treatments groups were composed to an uninfected negative control, an untreated infected positive control, an infected positive control treated with salinomycin, and two infected positive control treated with 1.5 and 3.00 ppm of phytotherapeutic-barbatim?o. The broilers at 30 days of age were infected with 2500 oocysts Eimeria maxima. Clinical parameters were evaluated by determining the damage score of the duodenum and jejunum from the chickens, and also oocysts count in feces and mortality were reported. And based on the performance indexes were evaluated feed intake, feed conversion, live weight and weight gain. The results showed only statistical difference in feed intake in early stage and growth stage (p < 0.05). The broilers to 42 days age were observed statistical difference in feed conversion, live weight and production viability (p < 0.05). Decreased the oocyst count in feces treated with phytotherapeutic-barbatim?o 1.5 and 3.00 ppm. In injury score, the positives controls treated with salinomycin and with herbal-barbatim?o 3.00 ppm had the lowest averages. Therefore, it infers that the grinded herbal peels from barbatim?o in tested doses 1.5 and 3.00 ppm assists in controlling avian eimeriosis acting reducing eliminated oocysts and the lesion score.
