Design of the study was a cross-sectional with a total of 339 beef blood samples collected to test for the presence of blood parasites by using of Giemsa-stained thin blood smear method. The results showed that the prevalence of blood parasites in beef cattle was . Two species were identified, Babesia bigemina and Anaplasma margina. The infected rate of Babesia bigemina and Anaplasma margina were and , respectively and multiple infection of both Babesia bigemina and Anaplasma margina was . Boophiplus microplus and Rhipicephalus sanguineus tick were and , respectively, among 231 samples of tick. Relative risk ratio was . This result showed that the exposure factor of blood parasites highly related with vectors of Boophiplus microplus and Rhipicephalus sanguineus with correction is 4,76. massive pandemic as infectious diseases, diseases caused by parasites have complicated development, spread out silently and smoulderingly, and finally create a significant loss to the livestock industry. Diseases with the highest impact are the blood parasite diseases, the Trypanosomiasis, Babesiosis, Anaplasmosis and Theileriosis (Nguyễn Hữu Hưng, et al., 2015). They fall under the list of dangerous diseases to animals (MARD, 2005). Findings of the research can help veteranians evaluate the circulating levels of blood parasite diseases on beef cattle in Cho Moi district, An Giang .
