Abstract: In order to reduce the loss of dairy production caused by the disease of abomasum displacement in dairy farms of scale, the incidence rate of abomasum translocation in dairy cows in 4 dairy farms for 3 consecutive years was investigated and analyzed. The results showed that the clinical diagnostic techniques and therapeutic effects of different treatments on the disease were compared and studied. The incidence of abomasum translocation was high within 20 days after parturition, and the dairy cows infected with abomasum translocation accounted for 84.15% of all the diseased cows. The incidence rate of abomasum translocation in dairy cows was 1.40%-2.13% in the surveyed 4 scale dairy farms, while there was no significant difference in the incidence among the farms (P>0.05). And the overall average incidence rate was 1.82%. Through clinical diagnosis, the disease could be diagnosed more accurately. The average cure rate of the surgical treatment method for the treatment of abomasum translocation in dairy cows was as high as 81.1%, while the cure rate of the rolling taxis for the clinical treatment of abomasum translocation in dairy cows was 20.41%. The difference of the treatment effect between the two treatment methods was extremely significant (P<0.01). In the production practice, it was suggested that the rolling taxis should be used for the initial treatment of the diagnosed diseased cows, and the surgical treatment should be used for the diseased cows with poor treatment effect, which could save the treatment cost and achieve better treatment effect.
