Prevalence of gastrointestinal round worms in calves in Sokoto, northwestern, Nigeria
Keywords:Prevalence, Gastrointestinal, Roundworm, Calves, Sokoto, Northwestern
An investigation to determine the prevalence and distribution of gastrointestinal roundworms in calves in Sokoto metropolis was carried out. A total of 216 faecal samples from calves were examined using Modified McMaster technique for morphological egg differentiation and count of worm-egg per gram of faeces of the sampled calves. Positive samples were cultured to differentiate between morphologically indistinguishable nematode genera. An overall prevalence was found to be 133 (61.57%). Eight different nematode genera were identified with Cooperia spp being highest in prevalence (28.78%) followed by Haemonchus spp (26.76%) and the least was Toxocara spp (0.50%). The prevalence was generally higher in females (56.39%) than in males (43.61%).
