Abstract

The black-fronted piping-guan (Aburria jacutinga) is and an endangered cracid species and little is known about its health. Hematology allows researchers to assess the health and physiological status of a population, but, to our knowledge, reference intervals are not available in the literature for A. jacutinga. Thus, the present study aimed to determine the hematological reference intervals of 31 captive black-fronted pipingguan adults in the state of Paraná, Brazil. Blood samples were collected from brachial vein and stored in heparinized tubes to be processed. The red blood cell (RBC) and white blood cell (WBC) counts were performed in a hemocytometer, and hemoglobin (HGB) concentration was obtained by the spectrophotometric cyanmethemoglobin method; packed cell volume (PCV) was determined by microhematocrit technique, and the mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) were calculated according to a previously established formula. The heterophil : lymphocyte ratio was calculated by dividing the number of heterophils by the number of lymphocytes. Determination of the 95% reference intervals and 90% confidence intervals were performed in accordance with American Society for Veterinary Clinical Pathology guidelines using Reference Value Advisor (version 2.0). The results obtained were as follows: RBC, 1.4–2.8 × 106/µl; PCV, 34.3–51.2%; HGB, 8.0–12.6 g/dl; MCV, 157.3–261.4 fl; MCHC, 22.0–26.7 g/dl; WBC, 2.3–33.1 × 103/µl; heterophils, 12.1–16.3%, 0.5–14.4 × 103/µl; lymphocytes, 19.8–69.0%, 1.4–16.4 × 103/µl; monocytes, 0.7–17.3%, 0.1–2.8×103/µl; eosinophils, 0.4–12.8%, 0.0–3.9 × 103/µl; basophils, 0.8–12.0%, 0.0–1.9 × 103/µl; and the heterophil : lymphocyte ratio, 0.2–3.0. The present study fills gaps in the literature on hematological values for A. jacutinga, which can be used to assess the health of the species populations. In addition, it contributed to establishing the health status of captive black-fronted piping-guans, indicating the possible welfare of the birds.
