Abstract


The experiment was carried out to determine the concentrations of total calcium and inorganic phosphorus of thirty rera obtained from pregnant Holitein cows, six sera from normal non-pregnant cows with one month after delivery, six sera from cows with ovarian cyst and six sera from heifer of sixteen months old. The changes of total calcium and inorganic phosphorus were observed on the 2nd, 4th, 6th, 8th, and l0th month of gestation.
The results obtained in this work were summarized as follows:
1. The mean values of total serum calcium obtained from the pregnant group were 9.59±0.34㎎/100㎖, from the non-pregnant group 10.23±0.47㎖/100㎖, from the infertility grou 10.37±0.27㎎/100㎖, and from the heifer group 10.07±0.20㎎/㎖. The change of total serum calcium values in the pregnant group revealed the tendency of decrease as gestation progresses and the lowest value appeared on the sixth month. The mean value of total serum calcium in the pregnant group was lower than those of the other groups, but the differences were not statistically significant.
2. The mean values of serum inorganic phosphorus obtained from the pregnant group were 5.82±0.31㎎/100㎖, from the non-pregnant group 5.92±0.44㎎/100㎖, from the infertility group 5.80±0.49㎎/100㎖, and from the heifer group 5.10±0.32㎎/100㎖. The change during pregnancy showed a slight fall and the lowest value appeared on the sixth month. The differences of serum inorganic phosphorus values between the pregnant group and the other adult groups were not significant, but these adult groups showed a significantly higher value than that of heifer group (p<0.05).
