Observations on genital abnormalities in dairy cows using slaughterhouse material.

The investigated material consisted of the sexual organs of 2010 cows, collected at a slaughterhouse during the years of 1971--74. The organs were examined macroscopically, with special regard to the ovaries, ovarian bursae, oviducts, and the uterus. The genital tract was cut open and examined for anomalies and other pathological changes. The results are presented in Tables I--IV. The total frequency of abnormalities within the investigated material was 18.2%. The most common disease condition was cystic degeneration of the ovary (8.6%). Bursal adhesions, parovarian cysts, and various forms of cervical anomalies constituted respectively 2.7, 2.3, and 1.7 per cent of the cases. The percentage of genital abnormalities as a cause of infertility was estimated to 1.5. The results have been compared with those of similar investigations.
