The objective of this trial was to evaluate the body temperature of cows with puerperal metritis within the interval of 10 days post partum. In addition, the body temperature of cows having a purulent and putrid character of lochia was compared. Rectal temperature was measured daily. The cows were examined clinically on day 10+/-3 post partum and were divided according to the character of lochia into Group M1 (purulent lochia, n = 29), Group M2 (putrid lochia, n = 28) and Group C (normal lochia, n = 35). The number of cows with a fever at least once during 10 days post partum was significantly higher in M1 and M2 than in C cows. In addition, there was a significantly higher number of cows with a temperature higher than 39.5 deg C in Group M2 in comparison with Group M1. The results revealed the following facts: higher incidence of body temperature higher than 39.0 deg C in cows with puerperal metritis; risk period for fever from Day 3 to Day 7 post partum; higher incidence of fever in cows with putrid lochia than in cows with purulent lochia; body temperature higher than 39.5 deg C being a more accurate indicator of puerperal metritis than the temperature higher than 39.0 deg C. Despite that, the occurrence of fever was irregular. In conclusion, to measure the body temperature is not sufficient to diagnose the puerperal metritis, although it may be considered a useful indicator to assess the severity of the disease.
