Evaluation of some biochemical parameters in serum of cattle with metritis

In this study, the changes of some biochemical profiles were measured in 50 cows with metritis septic (SM), 50 cows with post-parturient metritis (PPM) and 50 healthy cattle, using commercial kits. The results indicate significant decrease of calcium in cattle with metritis compared to healthy recently calved cows. Serum levels of magnesium were significantly lowered in SM group compared to PPM and control groups. Although serum concentration of phosphorus in sick animals was lower than healthy one, this decrease was not statistically significant. Lowest level of zinc of serum was reported in SM cattle (152.22 ± 8 µg/dl), which was significantly lower than PPM (168.04 ± 13 µg/dl) and control (192.25 ± 18 µg/dl) groups. Cattle with metritis (SM and PPM) had significantly lower serum levels of copper than healthy ones. Based on Pierson correlation analysis, there were significant negative correlation between calcium of serum and rectal temperature and with heart rate. Also there were significant negative correlation between zinc of serum and rectal temperature, with heart rate and with respiratory rate. This finding suggested that supplementation of minerals including trace elements and non-trace elements to peri-parturient cattle can improve immune system and reduce the uterine disease in these animals.
