Biological variations of hematologic and biochemical parameters in cows during early lactation

The aim of the study was to determine biologic variations main parameters in cows early lactation and compare intra-individual other species. 50 were included experiment. Blood samples taken at moment calving, then on 1st, 7th, 14th 28th day after calving. CVi had following values: 1.9-5% for MCV, MCH, MCHC, GLU, TProt, ALB, UREA, Ca, P Mg; 5.1-10% RBC, Hgb, Hct, WBC, NEU, LYM, BHB, ALT, CHOL, TGC >10% PLT, NEFA, TBil, AST GGT. For MCH subject-based reference values or change value should be used. all except AST, population-based intervals used with caution. CHOL index individuality close 0.6 which means that can much more adequate use intervals. There is little effect parity (increase parity) no milk production. obtained are specific because they deviate from animal species human. Calculated RCVs varied 5.5% MCHC 41% AST. High many metabolic opens possibility development model longitudinal monitoring status individual animals during lactation. That requires further research.
