Abstract

A total of 1000 bovine feacal samples were randomly collected per-rectum from Hyderabad and its surrounding areas to determine the types and prevalence of coccidian parasites. Coccidian oocysts were found in 6.6% of all samples examined. Eimeria bovis66 (6.6%) was the most prevalent species in the buffalo calves. During the present investigation four species of nematodes were also identified. The species detected and their prevalence were Toxocara vitulorum 80 (8.0%), Hemonchus contortus 09 (0.9%), Strongyles 05 (0.5%) and Ostertagia ostertagai 04 (0.4%). The highest percentage of coccidiosis 9.36% was recorded from cattle colony Hyderabad and lowest 1.23% from Pusia village. Other species of gastrointestinal nematodes were also identified from the different localities of Hyderabad but it was concluded that E. bovis was the most prevalent species in the calves specifically at the areas of Hyderabad.
