Abstract
Faecal samples from adult sheep and lambs were collected per rectum over one year survey. The number of oocysts per gram (OPG) faeces were determined by the McMaster technique and the identification of oocysts was made on sporulation. Infection was recorded throughtout the year,infecting on avarage 42.9% adult sheep and 74.6.% of lambs. OPG of less than 1000 were found in 45% of adults and 48% of lambs.The over all prevalence of Eimeria oocysts in faecal specimens was 58.8%. The infection pattern varied with system of husbandry, under zero grazing the infection was significantly (P<0.05) higher in both lambs (76%) and adult animals (49%), whereas under free range system the infection rate was significantly (P <0.05) more prevalent in lambs (70%) than in adults (33%). The prevalence of infection did vary with the season of the year and high numbers of both lambs and adults were found infected with the parasites. Eleven species of Eimeria were Identified . Eimeria ovina was the most common species with an over all prevalence of (60%), followed by E. ovinoidalis (47%), E. ahsata (42%), E. crandallis (33%), E. faurei (28.9%), E. parva (27%), E. marsica (12.7%), E. pallida (11%). Other species less prevalent species are E. intricata (9.7%), E. granulosa (7.7%) and E. punctata (0.9%).
