Objective With the increase in the level of yield of dairy cattle,the impact of reproductive diseases on the infertility of dairy cattle has become increasingly prominent,and oviductal diseases are easily neglected.Methods In order to clarify the basic diagnostic ideas of the fallopian tube diseases in dairy cattle.The research was conducted on 476 infertile dairy cattle in large-scale dairy farms in Xinjiang.The study involved medical history investigation,rectal examination,and B-ultrasound scanning diagnosis.Follow-up slaughter sampling was performed to complete morphological examinations such as organ appearance observation,pathological anatomy,fallopian tube irrigation,and histopathological examination.Results The study revealed that out of the 12 cases of cows with fallopian tube disease,there were 5 cases of simple fallopian tube disease,3 cases of uterine disease complicated by fallopian tube disease,and 4 cases of ovarian disease complicated by fallopian tube disease.Among these cases,5 did not exhibit any abnormalities during rectal palpation,ultrasonic examination,and necropsy.However,there was a slight resistance observed during the perfusion of the fallopian tubes,and histopathological examination indicated the presence of a small quantity of fallen ciliated cells in the fallopian tube mucosa.The accuracy of rectal palpation was improved to 58.3%(7/12)when combined with ultrasound,compared to rectal palpation alone.Conclusion The research results provide a reference basis for the diagnosis and prevention of reproductive diseases in dairy farms.
