To study changes in the concentration of some macro and micro minerals of allantoic fluid, fifty normal gravid uteri of Gaddi sheep at different stages of gestation were collected from local slaughter houses. After expelling each fetus accompanied by fetal membrane, 10 ml allantoic fluid was collected for mineral analysis. The foetii were measured for their crown rump length and then divided into 4 age groups i.e. group I (31-60 days), group II (61-90 days), group III (91-120 days) and group IV (121-till term). The mean concentration of sodium and chloride showed a declining trend as the gestation advanced. The level of potassium increased significantly from group III to group IV. The mean concentration of calcium and zinc increased with the progression of gestation. Statistical analysis revealed no significant difference in the respective concentrations of copper and iron among different age groups. Moreover, significant correlation was observed between the level of minerals (potassium and phosphorus) and foetal age. Changes in the concentration of minerals in the allantoic fluid reflect deviation in their uptake or metabolism and can be used to assess the healthy state of pregnancy and growth of the foetus.
