Abstract

A study was conducted to determine the prevalence of ovine fasciolosis in Debre Berhan region based on clinical, abattoir and field survey from November 2007 to March 2008. Of total 475 ovine faucal samples examined 229 (48.21%) positive for fasciolosis. Sex wise Prevalence off sciolosis 73.05% in male and 26.95% in female animals. Statistical analysis of prevalence rate on sex basis showed no significant difference (P>0.05) infection rate between the two sexes. Age wise prevalence recorded was 67.79% in adult and 32.21% in young. Analysis of infection rates on age basis had no significant differences (P>0.05). Asite wise of fasciolosis were 28%, 13.68%, 19.37%, 32.63%, and 6.32% in Atekelt, Delacha, Genet, Kerafino and Seladigay respectively. Statistical analysis of prevalence rate on site basis showed significant difference (P<0.05) in infection rate between sites. Breed wise of fasciolosis was 75.53% local, 18.11% cross and 6.53% exotic breed is recorded. Statistical prevalence rate on breed basis showed significant difference (P<0.05). The monthly prevalence of fasciolosis recorded was, 12.42%, 39.16%, 37.05, 5.05 & 6.32% in November, December, January, February and March respectively. The difference in monthly prevalence was significant (P<0.05). The result of the study has been discussed in detail in comparison with the finding of other workers and in relation to site and ecological condition of the area that affects the prevalence rate of fasciolosis. Finally, appropriate control strategies implemented in the study area is recommended to reduce the impact of fasciolosis on livestock production in the area.
