Abstract

Solomon Musema Mussa

A cross sectional study was carried out to determine the prevalence and associated risk factors of Haemonchus contortus in small ruminants from November 2021 to June 2022 in Mitto district Silte zone southern Ethiopia. The present study revealed that the overall prevalence of H. contortus in small ruminants was 46.1 %, which indicated a high prevalence of the parasite in the study area. Of the examined animals, 52.1% sheep and 33.1% goats were found positive showing a statistically significant difference in prevalence (P <0.05). Similarly the prevalence of H. contor- tus infection between sexes and age groups showed significant difference (P < 0.05) 51.4% in females and 36.3% in males, between age 60 % in young and 44.1% in adult and 35.5% in old respectively. Therefore, due to its important health problem and impact on production in the study area, emphasis should be given to the control and prevention of H. contortus infection with further studies on species identification and larval ecology.
