ABSTRACT
The objective of the present study was to determine changes in biochemical constituents of goat allantoic fluid in different stages of gestation. Allantoic fluid samples were collected from 115 normal pregnant goat uteri at various stages of pregnancy. After expelling of each fetus accompanied by fetal membranes, 10ml allantoic fluid was taken from allantoic sac. Approximate ages of fetuses were calculated by using related formula. At five stages of the five months of pregnancy, the following results were obtained, respectively: creatinine concentrations were: 4.7, 9.3, 9.2, 12.6 and 12.1 mg/dl; uric acid:0.5, 0.2, 0.2, 0.3 and 3.8 mg/dl; urea: 122.7, 153.8, 77.3, 52.1 and 37.6 mg/dl; total protein: 97.8, 129.5, 99.7, 128.9 and 85 mg/dl; glucose: 10.3, 20, 9, 8.1 and 4.2 mg/dl; sodium: 75.3, 77.8, 75.3, 73.5 and 78.9 mmol/L; potassium: 5, 4.6, 5.3, 5.9 and 5.8 mmol/L; chloride: 70, 68.6, 46.9, 30.2 and 30.2 mmol/L.
