Abstract— Coccidiosis swine causes high economic loss, and its prophylaxis is usually performed by the use of chemical drugs. However, these chemical drugs are not allowed in agroecological, organic or biological dynamic systems of production. Additionally, there are concerns about pharmacological resistance and contamination by the presence of chemical residues in the environment and at the food of animal origin. The objective of this study was to evaluate the weight gain and the prevalence of coccidia in piglets submitted to the following treatments: alcoholic extract of propolis 30% (AEP), chemical treatment toltrazuril (CTT), negative control with grain alcohol (NCA) and negative control without treatment (NCT). By means of the individual weights and the number of coccidia at the faeces, it was monitored 216 piglets from commercial farms. Under the conditions of this study none therapeutic intervention provided benefits for weight gain and prevalence of coccidia. Thus, by making it possible the minimization of chemical drug use, these results allow us to suggest the laboratory periodic monitoring as a prophylactic control method for swine coccidiosis.
