Abstract

The objective of the work was to evaluate if the multiparous adult cows presented any difference in the values of hematological biomarkers compared to young primiparous Nellore cows from the Bolivian tropics. During the month of February 2021, a study was carried out with 14 multiparous adult cows and 13 young prim parous cows. The cows used were: Adult cows of 4561±95 days and young cows of 1535±99 days (p≤0.001). Leukocytes and granulocytes were above the normal range, without significant differences between adult cows and young cows. Erythrocytes were within normal range, although showing the significant differences (p≤0.05) between adult cows and young cows. Hemoglobin for both groups was above normal values without showing significant differences between two groups. The values of the mean corpuscular volume and the amount of hemoglobin in the red blood cell were within normal range, although for both components the adult cows have a higher value with significant differences (p≤0.0001). The values of the erythrocyte distribution width and platelets are also within the normal ranges. Although in these cases with significant differences (p≤0.05), the highest values were the young cows. It is concluded that adult cows presented some difference in the values of hematological biomarkers compared to young Nellore cows from the Bolivian tropics, however, they were not outside the normal ranges.
