The study was conducted from July, 2020 to April, 2021. The studied result showed that the common infection rate of rabbits was 79.21%. The infection rate of rabbits raising in Can Tho city was 81.55%, higher than that of the rabbits raising in Vinh Long province (77.69%). The rabbits at all age groups were infected with oocysts. Of which, rabbit coccidiosis with the high infection rate and intensity mainly occurred in the rabbit age groups from 30-60 days old (100%) and 61-90 days old (91.85%), the infection rate and intensity decreased gradually with the rabbit age groups >
90 days old (66.18%) and the lowest rate was in the reproductive rabbit group (52.59%). There were six species of Eimeria found in the rabbit farms in Can Tho city and Vinh Long provice
E. media, E. stiedae, E. magna, E. exigua, E. flavescens and E. vejdovskyi. Using toltrazuril and amprolium for treating coccidiosis in rabbits with a dose of 1.4ml of toltrazuril per 2.5 kg rabbit body weight, (trial II) or 1ml of amprolium per 25 kg rabbit body weight, (trial III) or 1.4 ml of amprolium per 2.5 kg rabbit body weight, (trial IV) for one day only gave the high treatment efficacy, this treatment regimen can be widely applied in the rabbit farms
