The objective of this retrospective field study was to associate the type and smell of discharge, the size of the uterus, the ovarian and treatment status, and the time to diagnosis of animals with chronic clinical endometritis (CCE) with the incidence of ovarian cysts and with a marked loss in body condition in German Holstein Friesian cows. 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.
这项回顾性实地研究的目的是，将患有慢性临床子宫内膜炎（CCE）的动物的分泌物类型和气味、子宫大小、卵巢及治疗状况、诊断时间，与德国荷斯坦弗里生奶牛的卵巢囊肿发病率以及显著的体况下降联系起来。从产后第14天到第42天被诊断为CCE的264头奶牛参与了本研究。此外，分析还纳入了动物的100天产奶量和胎次。通过逻辑回归分析，脓性阴道分泌物（≥50%为脓液）、不针对CCE对动物进行治疗的决定以及较高的100天产奶量被证明是卵巢囊肿发病率的显著因素。此外，分泌物类型与胎次以及分泌物气味存在相互作用，因为更多有恶臭脓性分泌物的动物以及更多初产时有脓性分泌物的动物出现了卵巢囊肿。高产奶量和胎次与过度的体况评分下降有关。此外，与子宫早期复旧的奶牛相比，更多诊断为子宫过大的动物营养状况大幅下降。
