This study aimed at identifying some epidemiological characteristics of rabbit coccidiosis in Viet Yen district, Bac Giang province and the medicines used in treatment of rabbite coccidiosis.The fecal samples were collected by rabbit age groups, raising seasons, hygiene condition and fecalstatus for identifying the infection rate and intensity by Fulleborn method. The analysed results showedthat, out of 575 samples, there were 459 positive samples (79.83%). The highest infection rate andintensity were in Quang Minh commune (87.76%) and the lowest infection rate and intensity were inBich Son commune (67.65). By age group, the lowest infection rate was from newborn to 4 weeks old(59.65%) and the highest infection rate was in 8 to 12 weeks old (89.82%). The highest infection rate wasin summer (90.56%) and the lowest infection rate was in winter (65.91%). On the other hand, in the goodhygiene raising condition, the infection rate was 57.80%, whereas in the bad sanitary condition, the infection rate was very high (97.71%). For the fecal status, the infection rate in the normal and watery feceswas 76.00 and 89.66%, respectively. The Viacoc and RTD-coccistop medicines have given very goodtreatment efficacy for rabbit coccidiosis that was the infection rate of rabbit reduced significantly with thelight infection intensity. Thus, the infection rate and intensity of rabbit coccidiosis in Viet Yen district, BacGiang provicne were medium in comparison with other publications
