GRIJALBA O, Juana et al. DETERMINATION OF HEMATOLOGICAL VALUES OF COMMON CROCODILE (Caiman crocodilus fuscus) IN CAPTIVITY IN THE MAGDALENA MEDIO OF COLOMBIA. Acta biol.Colomb. [online]. 2020, vol.25, n.1, pp.75-81. ISSN 0120-548X.  https://doi.org/10.15446/abc.v25n1.76045.

Caiman zoo breeding (Caiman crocodilus fuscus) has been developing with greater force in Colombia since the 90s. It is essential to evaluate the physiological ranges of the species to be able to assess those situations in which their health is threatened. The objective of the present study was to determine the typical hematological values of the Caiman (Caiman crocodilus fuscus) with the aid of the microhematocrit, the cyanmethemoglobin technique, and a hematological analyzer. The blood samples were taken from 120 young animals of both sexes in good health apparently (males 44 and females 76). The samples were taken from the coccygeal vein between the second and third interscalar space with lilac lid vacutainer tube whit acid ethylene-diamine-tetra-acetic as an anticoagulant. The animals are located in the middle of the Magdalena area in Colombia. The results obtained on average were Hematocrit: 23.36 %, Hemoglobin: 7.78 g/dl, Red blood cells: 3.89 106/µL, Average corpuscular volume: 60 fl, Average corpuscular hemoglobin concentration: 33.33 g/dl and Average corpuscular hemoglobin: 73.9 pg. This is the first study of hematological values for this particular species in Colombia.
