Diagnostic tool for the diagnosis of physiological and pathological conditions of the uterus in cows postpartum.

Objective: An important task of veterinarians in cattle husbandry is the early diagnosis of postpartum complications that can lead to infertility. The aim of the study was the evaluation of a new device to distinguish between physiological and pathological conditions of the uterus based on the determination of the time of uterine involution and the physicochemical properties of the vaginal discharge (lochia) during the first weeks after parturition.

Material And Methods: A total of 173 black-and-white Holstein-Friesian dairy cows were examined for any pathological alteration of the uterine involution on days 1-2, 6-8, 11-14 postpartum and, in case of pathological findings, additionally on days 18-22, 23-27 and 28-30 after parturition.

[Development of a color chart to distinguish between lochia from cows with a disturbed and undisturbed uterine involution post partum].

Objective: To describe the differences in the color of lochia from cows with undisturbed and disturbed uterine involution and to apply this to disease detection post partum.

Material And Methods: During the period from the 1st to the 16th day post partum, 10 cows with an undisturbed uterine involution and 15 cows with an impaired uterine involution were examined and the color of the lochia was documented.

Results: The differences in the color of the lochia from cows with and without a disturbed uterine involution were used to create a color chart.
