BLOOD SERUM CONCENTRATIONS OF THYROID HORMONES, TOTAL PROTEIN AND AMINOTRASFERASE DURING PREGNANCY, PARTURITION AND POSTPARTUM IN EGYPTIAN BALADI GOATS

Abstract

p < /span>arturition and postpartum periods in the serum of 13 Baladi goats carrying single and twin. Serum T3 levels significantly decreased (P<0.05) from day of mating to 4 weeks of gestation, thereafter, T3 slightly increased at the 10th week, then significant decreased (P<0.05) at day of Kidding. Serum T4 level was no significantly different between day of mating and 18th week. Thearafter, serum T4 levels decreased significantly (P<0.01) at the day of kidding. No significant differences were observed both in T3 and T4 values during p < /span>ost partum period. No significant changes were recorded between goats bearing singles and twins. Serum total proteins decreased (P<0.01) with advancing pregnancy. No significant difference in total protein concentration was noticed between goats delivering singles and twins. After parturition, serum proteins significantly (P<0.05) increased at one week post peartum, followed by a gradual significant (P<0.05) decrease till the 3rd week after parturition. Serum AST and ALT increased (P<0.05) with advancing p < /span>regnancy and reached the maximum level during the 20th week of gestation, then they decreased towards parturition. After parturition, the AST and ALT concentration fluctuated. Differences in AST and ALT were not significant between goats bearing single and twin foetuses throughout the pregnancy period.
