The studies were carried out in the North-West part of Poland. The investigation was conducted on 292 specimens of the Holstein cattle with added 50 percent of HF. The extensity and intensity of the coccidia infection were determined by means of the Willis-Schlaaf's and McMaster's methods. Six species of coccidia were found : E. bovis, E. auburnensis, E. zürni, E. ellipsoidalis, E. subspherica and E. cylindrica. Twenty seven percent of dairy cows and 49.6 percent of calves were infected. Number of oocysts per gram of feces in calves ranged form 333 to 2237. Observations on the dynamics of the coccidia invasion in calves during a yearly cycle exhibited the existence of two peaks; a vernal and an autumnal ones
