The aim of this study is to highlight the influence of early lactation physiological stage on the haematological, electrolytic, enzymatic and biochemical profiles in ewes. The studied parameters (WBC, RBC, Hb, Ht, MCV, MCH, MCHC, Ca, P-inorganic, K, Na, Cl, ALT, AST, CK, GGT, LDH, glucose, urea, cholesterol, triglycerides, creatinine, total proteins, albumin, total bilirubin) were determined in the 20th day of the lactation period, the results obtained being compared to those of the witness group of non-pregnant nor lactating ewes. Important variations of the studied parameters were observed. The WBC value (7.21 ± 0.29 m/mm3) decreased significantly (p<0.05); the calcium and phosphorus values (9.20 ± 2.56 ;4.25± 0.60 mg/dL) decreased non-significantly (p>0.05); the AST (21.60 ± 2.41 U/L) and GGT (12.10 ± 1.45 U/L) activity increased significantly (p<0.05); the glucose (66.1 ± 8.43 mg/dL) and cholesterol (47.90 ± 7.01 mg/dL) values decreased significantly (p<0.05). The results are correlated with the high energy demand in order to support the mammary gland intense activity of milk synthesis in the first third of the lactation period.
