EPIDEMIOLOGIC AND CLINICAL ANALYSIS OF PO ST PUERPERIUM ENDOMETRITIS IN DAIRY-COWS

The aim of the present study was to analyse some of the epidemiologica l factors involved in post-partum endometritis and their influence on the subsequent fertility in tunisian dairy herd as well as the effecti veness of various treatments. This study was carried on a number of 25 0 cows approximately from the same farm during four consecutive years in which a Reproduction survey such as the so-called Integrated Veteri nary Program of Action for Reproduction (PAVIR) was applied. The overa ll rate of endometritis was 17,2 p. cent. Significant factors suscepti ble to modify this rate were the age and season. By contrast, individu al repeatability and milk production were without effect. Corynebacter ium were the most often isolated from the vulvae and uterine cavity in respectively 39.5 p. cent and 52.5 p. cent of these cases of endometr itis. Treatments with Antibiotherapy and Prostaglandine F-2 alpha resu lted in a conception rate of 70 p. cent in the 120 days after calving. In conclusion, systematic clinical examination performed 30 day after parturition was found to be an important feature to preduce the detri mental effect of such post-puerperium endometritis and the majority of cases had recovered in an interval of time compatible with the herds economics.
