n order to determine the infection status of Brucellosis in sheep and goats，and to provide data support for its prevention and control in Zhucheng City of Shandong Province，an epidemiological survey of Brucellosis in sheep and goat farms was carried out. The results showed that no Brucellosis positive samples was found in 10 scaled farms. The apparent prevalence rate at group and individual level in small-scaled farms were 1.14%（1/88）（95% CI：0.00%~3.35%）and 0.16%（5/3 143）（95% CI：0.01%-0.30%），respectively.
