Abstract

A cross sectional study was conducted from November 2018 to April, 2019 in sheep and goat slaughtered in Kersa district with the objectives of evaluating the status of H. contortus and its associated risk factors. A total of 385 small ruminants (179 sheep and 206 goats slaughtered) were sampled using systematic random sampling from three municipal abattoir namely Kersa, Langey and watar town. During this study the adult H. contortus was identified grossly based on its location and morphological appearance. The data was analysed using SPSS software to determine the association between prevalence of the haemonchosis and risk factors. Accordingly, the findings of this study revealed that an overall prevalence 294/385 (76.4%) was recorded. High prevalence of disease occurred in sheep 145/179 (81%) when compared with goats 149/200 (72.3%) and there was statistically significant differences (p<0.05) between species. Among the males and females of slaughtered animals 68.5% and 84.9% were found positive for H. contortus, respectively; and showed there was statistically significant difference (p<0.001) between sex. The prevalence of haemonchosis in young and adult was 88.6% and 71.1%, respectively. There was statistically significance difference (p<0.05) between age groups. Based on body condition higher infection occurred in poor body conditioned (96.6%) followed by medium body conditioned animals 78.1% and the lowest prevalence was in good body conditioned animals (66.2%) and there was statistically significant differences (p<0.0001) between body condition. In general, high infection rate of H. contortus was observed in sheep and goats in the study area. Therefore, strategic prevention and control measures should be implemented to decrease the economic loss, parasitic infestation and to enhance productivity of animal in area.
