Prevalence of Heamonchosis in Small Ruminants and Its Associated Risk Factors in and Around Ejere Town, West Shoa, Oromia, Ethiopia| Biomed Grid

A cross sectional study was conducted from July 2017 to February 2018 for determination of small ruminant haemonchosis and investigation of associated potential risk factors in and around Ejere town, west shoa, Oromia, Ethiopia. The purpose of the study was to determine the prevalence and associated risk factors of Haemonchus in the area. The totals of 384 animals were included in the study from these 261 sheep and 123 goats depending on the number of small ruminants of the district they were taken randomly from whole animals. The overall prevalence was 63.02% which is lower than the previous reports. This is due the most pastureland is occupied by agricultural activity so that small ruminants are not exposed to this gastrointestinal parasite. The prevalence was higher in sheep (63.6%) than goats (61.78%). In case of species there was no statically significant difference (p > 0.05). The prevalence in young was higher as compared with adult small ruminants with prevalence of 74.72% and 52.47% in young and adult respectively. Depending on body condition the prevalence was higher in poor body conditioned animals (94.5%) due to lack of resistant against diseases and lower in good body conditioned animals (30%). There was significant difference between body condition and Haemonchus prevalence (p< 0.05). from all peasant associations the highest prevalence was recorded in Ilu aga (75.3%) and the lowest was observed in Chirri (48%) there was no significant difference between origin of animals and haemonchosis (p>0.05). The prevalence also higher in September (79.68%) followed by October (67.96%) and November (41.4%). late summer is favorable for Haemonchus to undergo its development and consumed with grass. The prevalence was higher in female (71.6%) than male (58.4%) due to females are always under stress of parturition and pregnancy. There is no significant difference between sex and Haemonchus prevalence (p >0.05). Further studies on the economic importance of helminthiasis and drug resistance patterns of anthelmintics should be conducted for the holistic implementation of helminthiasis control
