Variables hematológicas en aves deportivas, ganso común, pato doméstico, pato azteca, guajolote y pollo de engorda

Blood analysis in birds is an evidence that allows evaluating their health status and is a diagnostic tool for the clinical veterinarian. The objective of the research was to know the hematological variables of common birds, sport birds, common goose, domestic duck, Aztec duck, turkey and broiler chicken by sex, species and the difference between species. A blood sample was taken from 88 birds by venipuncture of the ulnar vein using EDTA as anticoagulant. Erythrocytes and total leukocytes were counted by the method of Natt and Herriks. Leukocyte differential was performed by blood smear, hemoglobin concentration was measured by the cyanomethemoglobin technique and microhematocrit percentage. Data were compared with an analysis of variance in a completely randomized design and differences were compared with Tukey's test (P<0.05). For eosinophils and basophils, the Kruskal-Wallis test was used because the data did not present normality. The hematological variables in sport birds, common goose, domestic duck, Aztec duck, turkey and broiler chicken were similar for females and males of the same species. But there were differences in white cells of the species studied.
