Aim of the present study was, to show relations between various
metabolic parameters and the occurrence of inflammatory diseases of
the uterus in dairy cows. Additionally, we wanted to find limiting
values that show an increased risk of disease if they were exceeded
or fallen short of. In eight dairy herds 124 cows and heifers were
examined weekly from week 2 before calving to week 5 postpartum.
Metabolic parameters in blood as total protein, albumin, total
bilirubin, aspartate aminotransferase, γ-glutamyl transferase,
glutamate dehydrogenase and β-hydroxy butyric acid were examined
once weekly from week 2 before to week 2 after parturition.
Parameters in milk such as fat, lactose, fat-/lactose-quotient,
protein, fat-/protein-quotient and urea were examined or calculated
in week 1 and 2 postpartum in cisternal and residual milk, body
condition was determined with body condition scoring on every date
of examination. Gynaecologic examinations were conducted in week 2,
4 and 5 postpartum. Furthermore, additional data as milk yield,
calving interval, dead births, problems at parturition, as well as
the time from parturition to first insemination and calving to
conception interval, was documented. For the evaluation of the
data, cows were divided into two groups. Cows, that suffered from
puerperal metritis, clinical metritis, clinical endometritis or
pyometra were assigned to the group “ill”. Cows, that didn’t suffer
from any uterine disease on one of the dates of examination, were
assigned to the group “healthy”. If there were significant
differences in parameters between groups, we formed limiting values
for these parameters. The exceeding or deceeding of these limiting
values showed a higher risk of disease. Probably the energy
deficit, which is reflected in the change of metabolic parameters,
is most likely responsible for an impairment of the immune system
and thereby for the higher risk of suffering uterine disease.
