Target Species: Poultry (Broilers, Breeders), Geese and Turkeys


Bayzoril® is a broad spectrum anticoccidial for treatment of coccidiosis in poultry. It is highly effective not only against all coccidia of chickens (E. acervulina, E. brunetti, E. maxima, E. mivati, E. necatrix, E. tenella) and turkeys (E. adenoides, E. meleagrimitis), but also against coccidiosis in geeses (E. anseris, E. truncata).

Mechanism of action:

Toltrazuril is effective on all intracellular developmental stages of coccidia and interferes with the division of the nucleus and with the activity of the mitochondria, which are responsible for the respiratory metabolism of the parasites and reduces the enzymes of the respiratory chain of the parasite. Thus, the coccidiocidal effect of toltrazuril is more than its coccidiostat effect.

Dosage & Administration:

The basic dosage in poultry is 7 mg/kg or 0.28 ml of  per kg of body weight and usually, once treatment for 2 consecutive days is enough. If necessary, it is better to repeat the treatment after 5 days.

500 ml per 500 liters of drinking water for 2 consecutive days or 1500 ml per 500 liters of drinking water every 8 hours for 2 consecutive days.
