[Objective] The purpose of this study was to understand the infection status of Brucellosis,Toxoplasmosis,Chlamydia and Neosporidiosis in aborted cows in some dairy farms in Langfang City. [Method] Select 265 blood samples from Holstein cows with a history of miscarriage in 10 dairy farms,and use serological testing methods to detect four pathogens. [Result] The results showed that the average positive rates of Brucella,Neosporidium canis,Toxoplasma gondii and Chlamydia were 1.13%,3.40%,5.28% and 4.53%,respectively,and the highest positive rates were 6.67%,8.70%,9.68% and 13.33%,respectively. The field positive rates were 30%,60%,80%,and 70%,respectively. The total positive rate of the four pathogens was 14.34%. [Conclusion] The research shows that there are four kinds of epidemic diseases among aborted dairy cows in Langfang Dairy Farm. Although the infection rate is low, attention should be paid to further strengthen prevention and control and purification.
