| Selected blood parameters in cows at the periparturient period and increasing lactation |
| The aim of the study was the comparison of selected blood parameters in three different groups of cows: in mid lactation, 100-150 days after calving (17 cows), in dry period, 7-3 days before calving (14 cows) and 3-5 days after calving (11 cows). The cows were clinically healthy and were kept in good environmental and nutritional conditions with mean productivity per lactation of approximately 7000 kilograms of milk per cow. Twenty-two different biochemical and morphological blood parameters were analyzed. The values of some blood parameters like: erythrocyte count, leukocyte count, hemoglobin level, haematocrit, levels of glucose, urea, creatynine, Ca, Mg, GPT activity, and values of pH, pO2 were similar in all groups of cows. Statistically significant differences between the tested technological groups of cows were noted for the remaining parameters like: levels of biliribin, total protein, albumins, GOT activity, concentrations of K, Na, Pn (inorganic phosphorus), Cl, activity of GOT and values of pCO2, or BE. The results of these investigations may be useful for veterinarians responsible for prevention and the therapy of the cattle. |
