CHANGES IN RENAL FUNCTIONS DURING THIRST PERIODS INMARWARIGOAT

摘要

To observe the changes in renal functions during thirst periods, a study was carried out in five healthy adult female Marwari goats. The experiment was divided into control, thirst and drinking periods. The renal functions included glomerular filtration rate (GFR), effective renal blood flow (ERBF), filtration fraction (FF), urea clearance (Cum) and transfer function of kidney (TFK). The mean values were 35.11 +- 1.34 ml/min; 251.70 +- 6.03ml/ min.; 0.20 +- 0.007; 20.16.98 ml/min and 0.48 +- 0.03, respectively during control period. The mean values of all the clearances decreased significantly (p<=0.05) during thirst period and then increased gradually upon drinking. The observations for TFK were recorded during control and drinking periods.
