Abstract:
Helminths parasite infections in sheep were the major importance in many agro-ecological zones and are
a primary factor in the reduction of production and productivity of sheep. The main objective of this study
was helminths parasites and their economic loss caused on sheep with its control approach at the study
area. A cross-sectional study using a simple random sampling procedure was used to study helminths
parasite identification at Gudaya Bila district in 2022 with in two season of the year in winter (January -
March) and summer season (June -August). Out of 384 sheep chosen at random sampling from five (5)
kebeles in the Gudaya Bila district (Walane Lemmu, Haro Guddisa, Chali Jima, Hagalo Gidami, and
Bila) were under go flotation and sedimentation procedures about 149 sheep were infected by helminths
parasites and about 235 are none infected. Then the overall prevalence of helminths parasites from the
study area was 38.8%. The prevalence of helminths parasites class at the study area were Trematoda
51(13.28%), Nematoda 45(11.72%) and Cestoda 3(3.9%). The helminths species that had highest
prevalence found was Fasciola species (19.5%), Haemonchus species (14.76%), Strongyloides species
(10.74%),and Schistosoma species (9.4%),and that had least prevalence are Monieza species (6.04%),
Monieza species (5.4%), Taenia species (4.02%),Nematodirus species (3.3 %) and Trichostrongylus
species (1.34 %). The summer season was favorable for helminths parasite transmission and larval
development. The prevalence of helminths in summer season was 98 (25.52 %), and the winter season
was 51(13.28%). These helminths could affect the economy of people through meat production, Weight
loss, and buying antihelmenths slow growth rate, death of sheep and Morbidity of the sheep. Since the
helminths can affect health of sheep people at the area the can control parasite by using traditional
medicinal plants. The study shows that the gastrointestinal helminths parasite was a major important
health problem and impact on the production of sheep in the study area. Therefore, a detailed study
should be conducted to identify the parasite at the species level and further investigation will be needed to
study on the association of prevalence of helminths parasites within age, sex and agro ecology of sheep in
the area. Then educating the people about the impacts of helminths is must needed to control them
