Abstract
Cystic ovarian disease (COD) was studied in a closed 300-cow dairy herd, using Dairy Herd Improvement Association and individual health records for a 7-year period (1974-1980). There were 2,112 calving by 649 cows during the period. Cysts were found in 130 cows. Of the 649 cows that calved, 110 (16.9%) produced at least 1 daughter in which COD developed. Two bulls sired 17.6% of the daughters with COD, which was more than anticipated inasmuch as they sired only 11.6% of all daughters (P<0.05). These bulls were removed from the breeding program in an attempt to reduce COD in the herd.
