The study was carried out on material consisting of 3375 rabbits of the White New Zealand breed. The total number of 9 species of coccidia were found, 8 of which were intestinal (E. perforans, E. media, E. magna, E. irresidua, E. coecicola, E. flavescens, E. Piriformis oraz E. intestinalis) and E. stiedai inhabiting the liver. Three specirs - E. irresidua, E. Coecicola and E. flavescens have been found in Poland for the first time. Three of four coccidiostats examined ie. Sacox, Cycostat and Baycox may be used to prevent coccidiosis in rabbit farm. Activity of Vetrocox is less effective and it should not be used in the prevention of coccidia infection. At the age of 90 days the best results were obtained by treatment of Sacox (257 g of increase body weight and 9 per cent lower mortality comparing with the control group ); the second test result was after two doses of Baycox and after Cycostat treatment.
