Evaluation of the anticoccidial effect of jataí bee (Tetragonisca angustula) propolis extract against Eimeria spp. oocysts in broiler

The use of anticoccidial compounds is the primary strategy for controlling avian coccidiosis. The emergence of drug resistance, regulatory restrictions, and societal demands for meat production without the use of antimicrobials have increased the need for natural alternatives to control this disease. Propolis is known for its antimicrobial effects and may be an alternative. In this context, this study aimed to evaluate the anticoccidial activity of jataí bee (Tetragonisca angustula) propolis against the sporulation of Eimeria spp. oocysts in broiler chicken feces. Propolis ethanolic extracts were tested at 10, 15, and 20% against Eimeria oocyst sporulation. Direct use of the extract on oocysts completely inhibited sporulation. When applied to feces, the extract significantly reduced the number of sporulated oocysts. Thus, the jatai bee propolis extract is a promising alternative to commercial anticoccidial agents.
