Influence of lactation stages on haematological and biochemical parameters in blood of Lacaune dairy sheep

The research objective was to determine haematological and biochemical parameters in blood of 30 Lacaune dairy sheep during different stages lactation (early: 60th, medium: 120th late: 180th days). were on average 4 years old, 3rd lactation. Haematological determined whole (white cell (WBC), red (RBC), haemoglobin (HGB) concentration, haematocrit (HCT) value, mean corpuscular volume (MCV), (MCH), concentration (MCHC) platelet (PLT) count), a smear used for determination differential count. Determined serum were: minerals (Ca, P-inorganic, Mg Fe), total proteins (TP), albumin (ALB), globulins (GLOB), urea, glucose (GUK), cholesterol (CHOL), high-density lipoprotein (HDL), low-density (LDL), triglycerides (TGC), beta-hydroxybutyrate (BHB) non-esterified fatty acids (NEFA), enzyme activities (aspartate aminotransferase (AST), alanine (ALT), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), creatine kinase (CK), activity glutathione peroxidase (GPx) superoxide dismutase (SOD). With progression stages, tests proved significant increase WBC, RBC, HGB, HCT, monocytes, Fe, TP, ALB, CHOL, HDL, LDL, BHB, AST, GGT ALT as well decrease lymphocytes, Mg, GUK SOD. changes good quality nutrition indicate the need include this breed/genotype prospective schemes definition referential values these indicators sheep.
