OBJECTIVES: The aim of the present study was to determine prevalence of hydatid cyst in sheep and its structure with age. METHODS: During 2009, 786 sheep in different age groups (1 to 6“ |years) slaughtered at Babol abattoir, Mazanderan province were examined for hydatid cyst infection through visual examination, palpation and slicing the infected organs into pieces. The number of cysts was counted and their mean volume, diameter, and number of protoscoleces in different age groups were determined. RESULTS: Our findings showed the overall prevalence rate of infection 35.2%. There was a significant relation between age and considered parameters (p UR - https://ijvm.ut.ac.ir/article_30004.html L1 - https://ijvm.ut.ac.ir/article_30004_0d03ec5e993811713f4d0e88c5216d94.pdf ER -
