Evaluation the effect of placenta on some clinical biochemical parameters during different reproductive periods in New Zealand white female rabbits

Abstract

The current study was conducted to evaluate the effect of different reproductive periods on some biochemical parameters (ALP, ALT, AST and GGT) in New Zealand white female rabbits. The study was carried out in the animal house of the college of veterinary medicine in Al- Qadisyia university on 21 female New Zealand white rabbits, the animals were divided to 3 groups each group contain 7 rabbits: group A as control non-pregnant rabbits, group B were pregnant rabbits and final group C were lactating female rabbits. Fresh blood samples (4 ml) were collected and centrifuged to obtained serum, then Reflotron apparatus was used for estimation of some enzymes (ALP,ALT, AST and GGT) in all groups of the experiment. The results of group A revealed that the means of (ALP, ALT, AST and GGT) were (44.54, 45.52, 20.74 and 6.08) U/L respectively, while the means of enzyme levels in group B were (105.9, 48.08, 22.68 and 6.8) U/L respectively, and the means of enzyme levels in group C were (49.9, 46.21, 21.84 and 6.72) U/L respectively. The levels of ALP in group B showed a significant increase (P<0.01) as compared with A and C groups, while there no significant increment among sera of three groups levels of (ALT, AST, and GGT).
