Prevalence of bovine coccidiosis in Soc Trang province

Abstract

A survey on the prevalence of bovine coccidiosis was conducted in Soc Trang province from
October, 2021 to May, 2022. The objective of study aimed to determine the prevalence and identification
of Eimeria species. A total of 363 cattle fecal samples were collected from three different cattle age
groups: under 6 months old, 6-12 months old, and over 12 months old in the surveyed areas for identifying
coccidiosis. The studied result showed that 38.57% of cattle raising in Soc Trang province were infected
with Eimeria species. The cattle at all ages were infected with coccidiosis. The highest infection rate
was found in the cattle age group under 6 months with 60.00%, followed by the cattle age group at 6-12
months old with 45.67% and the lowest infection rate was found in the cattle age group over 12 months
old with 17.73%. The infection intensity with Eimeria species of fecal samples at level 1+, 2+, 3+ was
67.86%, 25.71%, and 9.29%, respectively. The appeared frequency of Eimeria spp. in diarrhea fecal
samples (62.86%) was higher than that in the normal fecal samples (58.33%). Five different Eimeria
species were identified, including E. bovis, E. zuernii, E. alabamensis, E. canadensis, and E. auburnensis.
Among them, E. bovis (16.12%) and E. zuernii (8.82%) were considered to be the two highly virulent
species causing coccicosis in cattle in Soc Trang province; followed by 3 species: E. alabamensis, E.
canadensis and E. auburnensis with the appeared rate was 7.16%, 6.61%, and 5.51%, respectively. The
cattle raising in Soc Trang was infected at the same time with 2, 3, 4, 5 Eimeria species with the infection
rate was 27.86%, 11.43%, 9.29%, and 7.14%, respectively
