Helminthosis are one of the worlds most prevalent and economically essential parasitizes of human and domesticated animals.

The study was aiming at investigating gastrointestinal parasites in cross-breed dairy cattle reared in Nyala city. A questionnaire survey was done before collection of samples. A total of 110 faecal samples were collected from dairy cattle in Nyala city. Faecal samples were subjected for parasitological examination using Floatation and Sedimentation techniques. Faecal slides were examined under low power microscopy. Helminth eggs were detected in 65 (59.1%) faecal samples. 45 percent of the parasitic infestation cases were mixed cases (e.g. mixed Nematodes, and Trematodes and Coccidia spp.). Nematodes eggs were found in 24 (21.8%) samples, Trematodes eggs in 21(19.1%) samples and Coccidia spp. in 20 (18.2%) samples. 10 Paramphistomum spp. were detected and the prevalence of Paramphistomum spp. was 9.1%. 6 Schistoma heamtobium were detected and the prevalence of Schistoma heamtobium was 5.4%. 5 Fasciola gigantica were detected and the prevalence of Fasciola gigantica was 4.5%.
