Efeitos da estocagem sobre os principais parâmetros hematológicos de equinos

Abstract

Today, horses are used for work, as well as to sports, therapies and recreation. As a result, there is a greater concern for their health, consequently, there is a high demand for laboratory tests, especially blood count, which is a test that can help diagnose various diseases. This examination should be performed as soon as possible to prevent changes in results. Thus, the aim of this work was to evaluate the stability of hematological parameters samples under refrigeration (2 to 8 ° C) for seven days. Blood samples from nine horses were used and evaluated in the following moments: 0h, 12h, 24h, 48h, 72h, 96h, 120h, 144h e 168h. According to the results, it was observed stability throughout the experiment for red blood cell count, hemoglobin, hematocrit, white blood cell and platelet counts. The value found for MCV in 168 hours, was significantly higher than the values at the moments 0h, 12h and 24h. MCHC significantly decreases from 96 hours. So, it can be concluded that the cooling maintains the stability of samples for three days (72 hours), but if the animal does not present anemia, stability of samples can be considered to seven days (168 hours).
