STUDY ON PREVALENCE AND CYST CHARACTERIZATION OF HYDATIDOSIS IN CATTLE SLAUGHTERED AT WOLAYTA SODDO MUNICIPAL ABBATTIOR

A cross-sectional survey of bovine hydatidosis was conducted on local zebu cattle slaughtered at Wolayta Soddo Municipal Abattoir from November, 2012 to March, 2013 to determine the prevalence and cyst characterization caused by hydatid disease.
