THE SERUM BIOCHEMICAL PROFILE OF THE RABBIT OF THE ALGERIAN POPULATION IN THE SEMI-ARID REGIONS OF AURES (BATNA) AT DIFFERENT PHYSIOLOGICAL STAGES

Abstract

One hundred and twenty local Algerian female rabbits in first parity were used in this present study at the experiment farm of the University of Batna 1. The animals were divided into four equal groups with 30 replicates (empty female, pregnant female, pregnant-lactating female and lactating female only). Natural mating was used, the kits were weaned at 28 days. Four blood samples were collected on females at different physiological stages. The physiological status affected significantly (p < 0.05) cumulative BCS, milk yield, litter size and litter weight of does at birthing. Total protein, albumin, globulin, uric acid and creatinine concentrations as well as T3 and progesterone levels were higher (p < 0.05) in does of P-L group (5.70±1 g/dl, 2.98±0.07 g/dl, 1.88±0.06 g/dl, 34.9±3.4 mg/dl, 1.3±0.4 mg/dl, 44.3±0.93 ng/dl, 18.98±1.5ng/ml) respectively. The physiological status increased significantly (p < 0.05) total lipids, triglycerides and total cholesterol in does of P, P-L and L groups compared with their concentrations in E group. The physiological status affected alanine aminotransferase (ALT), aspartate aminotransferase (AST) and Alkaline phosphatase activities in does during pregnancy and suckling period (5.65±0.1UI/L, 22±1.3UI/L vs 5.45 ±0.22, 20.35±4.3UI/L). Does of P, P-L, and L groups had higher (p < 0.05) leptin levels. Insulin and glucose concentrations were increased in P and P-L groups compared to E and L groups.
