Hematological profile in holstein dairy cows according to the different physiological stage

This study aims to investigate the variations of hematological and ionic parameters Holstein dairy cows according physiological stage, as an indicator their health status. The survey was conducted between January March, 2020 carried out on 4 lots 15 each. analysis blood included: red cells (RBC), hematocrit (HCT), hemoglobin (HGB), mean corpuscular volume (MCV), content (MCH), concentration (MCHC), platelets (PLT), white (WBC), lymphocytes (LYM), monocytes (MONO), neutrophils (NEU), eosinophils (EOS), basophils (BASO) such potassium (K), chlorine (Cl), calcium (Ca), phosphorus (P) sodium (Na). RBC level lowest in 2nd third gestation (6.0 ± 0.8 x 106/μL) postpartum period (5.6 106/μL), comparison 1st (6.6 0.6 106 / μL) 3rd (dry period) (6.7 0.5 (p<0.0001). same observation noted for HCT MCV highest dry (p<0.01). MCH MCHC were that (p<0.001). For WBC, count higher 1stthird compared other stages, (11.3 2.2 103 versus (6.4 4.1 μL), (5.2 1.3 (8.0 4.9 third, gestation, postpartum, respectively (p<0.001).In cows, had values (Ca) tothe stages investigation can be used a basis information profile cattle order determine status before onset clinical signs.
