Analysis of Correlations between Selected Blood Markers of Acid-Base Balance, Blood Electrolytes, and Milk Components in Dairy Cows during Late Lactation

The aim of the study was to assess values and correlations between selected markers acid-base balance electrolytes in blood late lactation cows, such as pH, pCO2, pO2, HCO3 –, BE, BE(B), Na+, K+, Cl–, well parameters milk, number somatic cells (SCC), colony forming units (CFU), milk fat (MF), protein (MP), lactose (ML), solids, solids non-fat (SNF), current production. Blood samples were collected at same time from 11 clinically healthy milking cows later period. Those examined once a day for 3 consecutive days resulting 33 sets used laboratory statistical analyses. Significant positive observed pH pCO2 – BE Na+ production, Cl– MP. negative BE(B) Cl–. increase significantly negatively correlated with while or associated significant decrease amount milk. These relations can indicate influence imbalance on quantity quality cow’s repeatable diagnostic model presented here proved be very useful tool detailed assessment higly sensitive internal homeostasis productive dairy cows.
