The Effects of Pre-weaning and Post-weaning Feeding Periods on Biochemical Parameters in Terms of Metabolic Profile in Dorper and Lacaune Lambs

Background: This study was conducted to evaluate the effects of feeding on biochemical parameters in terms metabolic profile female and male lambs Dorper Lacaune breeds at developmental stages from birth. Methods: A total 32 singleton newborn breed (n= 8 for each group; female) were used. The trial continued 5 nutritional periods 21-day after first two weeks (0-14 days) suckling period. determined paraoxonase 1 (PON1), ischemia modified albumin (IMA), protein (TP), (ALB), aspartat amino transferase (AST), alanin (ALT), alkaline phosphatase (ALP) malondialdehyde (MDA). Result: PON1 activity all found be low during period (P≤0.001). highest IMA value reached against decrease TP ALP levels weaning There no difference between groups PON1, TP, ALB ALP. Increases observed AST, ALT, MDA Dorpers. (P≤0.05). It concluded that adaptation solid feeds may cause oxidative damage or variable
