[The diagnostic and prognostic significance of ketonuria in fertility disorders of cattle].
The diagnostic and prognostic significance of ketonuria for the prognosis of reproductive disorders in high-performance dairy cows was examined in 3 herds of Holstein Friesian and Holstein Friesian x Hungarian Red Pied F1 that were either primiparae or were due to calve for the 2nd to 8th time during the study period from mid-February to late March, 1988. The course of uterine involution and status of the ovaries was followed up by regular rectal and vaginal examination. In the first experiment (n = 15) the return of cyclic ovarian activity was monitored by determination of progesterone in milk twice weekly over a period of 10 weeks post partum. In the second experiment (n = 121) urine and milk samples were collected at intervals of 5 to 8 days over a period of 9 weeks post partum and analysed for ketone bodies. The body condition of the cows was estimated by a scoring system at 5 and 9 weeks post partum. In the third experiment (n = 289) urine samples taken 1-4 days before as well as 3 days and 5 weeks after calving were analysed for ketone bodies. Biologic reproduction data were followed up for 150 days post partum in all experiments. One to two thirds of the cows in the examined herds showed ketonuria post partum, some animals also displayed ketonuria ante partum. Persistent postpartal ketonuria occurred mainly among the older cows with a high performance that at the same time showed a marked loss of body condition during the first weeks post partum. Primiparous heifers seldom developed ketonuria, despite a generally poor body condition.(ABSTRACT TRUNCATED AT 250 WORDS)
