Influência do armazenamento do sangue bovino por 24 e 48 horas à temperatura ambiente e de refrigeração sobre os valores hematológicos

Abstract

This study aimed to evaluate hematological parameters, taking into consideration the storage time and temperature of the blood samples. Blood samples were collected from 53 young, and adult cattle, 30 of which were stored at room temperature for 24 and 48 hours and stored refrigerated for the same period. Each sample was divided into two aliquots of 1 mL, into microtubes totaling 106 aliquots. The elements of the erythrogram, leukogram and platelet were evaluated in each aliquot. For the statistical analysis, the ANOVA and Kruskal-Wallis tests were used. When statistical differences were detected at a significance level of 5%, Tukey and Dunn post-tests were performed to show statistical differences between the means at moments 0, 24 and 48 hours. The erythrogram elements were statistically similar; mean platelet volume (MVP), neutrophils in rods, eosinophils, and monocytes differed significantly when stored for 24 and 48 hours. It was concluded that storage time and temperature for up to 48 hours interfere with the number of neutrophils in rods, eosinophils, and monocytes and mean platelet volume (MPV).
