Two hundred and sixty-four cows diagnosed with CCE from day 14 to day 42 postpartum participated in this study. In addition 100 days milk production and the parity of the animals were included in the analysis. With the use of logistic regression a purulent vaginal discharge 50 pus the decision not to treat the animals for CCE and a high 100 days milk production proved to be significant factors for the incidence of ovarian cysts. Additionally the type of discharge showed interactions with the parity and the smell of the discharge as more animals with fetid and purulent discharge and more animals in the first lactation with a purulent discharge developed ovarian cysts. A high milk production and the parity showed associations with an excessive body condition score loss. Additionally more animals with a diagnosis of an oversized uterus in comparison to cows with an early involution experienced a considerable reduction in their nutritional condition.
