Blood biochemical parameters, electrolytes and hormones in the dam and her calf after parturition of Egyptian buffalo.

The aim of this study was to characterize the physiological changes in plasma calf during the first month of life compared to changes in their mothers. Results indicated that, the concentrations of plasma glucose were decreased with time from the moment of birth until the end of the first month after birth in both dam and her calf. The concentrations of plasma urea, total protein, cholesterol and triglyceride were increased in both dam and calf from zero time to four weeks, while plasma creatinine was decrease. There were a drop in calcium, potassium and phosphorous levels in dam while in the plasma of calf calcium and phosphorus levels were increase while potassium level was decrease. The concentrations of plasma sodium were increased in both dam and calf from zero time to four weeks. Chloride concentrations varied in both dam and calf. The concentrations of plasma IGF-1 in dam were decrease from zero time to four weeks, while the level in calf was increase, the opposite trend recorded in leptin levels. The concentrations of plasma T3 were decrease in dam and her calf, The T4 concentrations show high concentrations of thyroid hormones, particularly in the first week of age, with their subsequent decreasing.
