title: Prostaglandin treatment and subsequent cystic ovarian disease in Holstein cows.
abstract: Using computerized herd health data, a prospective cohort study was devised to determine whether cows treated with prostaglandins had a higher incidence of cystic ovarian disease than comparable cows not treated. Of 744 cows selected as having diseases for which prostaglandin administration may be indicated, 240 received prostaglandin. Sixteen cows had cystic ovarian disease following prostaglandin administration. Chi-square analysis showed no association (P greater than 0.10) between cystic ovarian disease and the use of prostaglandin. Incidence of cystic ovarian disease within 150 days of calving in clinically normal cows was compared with that of cows with reproductive disorders. Cows with reproductive disorders had a significantly (P less than 0.01) higher incidence of cystic ovarian disease.
