Determination of Hematological Values of Common Crocodile (Caiman Crocodilus fuscus) in Captivity in the Magdalena medio of Colombia

“…The variation (2.1 g/dL) was higher than that found in our study, which was 1.34 g/dL (Table 2). In the study carried out by Barboza et al (2011) the hemoglobin of Caiman latirostris was 6.26 g/dL for diet 1 (balanced feed and crude protein 38 %), while for diet 2 (balanced feed and 64 % of crude protein) was 6.04 g/dL; those results are closer to the minimum value found in our study, which was 5.66 g/dL, despite being different species with different diet.…”

“…However, it was among the range found in our study, which ranges from 27.82 g/dL to 38.83 g/dL (Table 2). The CMCH reported by Barboza et al (2011) for Caiman latirostris was 30 g/dL on average, for both diets, varying from what was reported in our study, which was 3.33 g/dL (Table 2). According to authors who worked with Alligator sinensis (Peng et al, 2018), the CMCH was 34.24 g/dL for males and 34.75 g/dL for females, results that were higher than found in Caiman crocodilus fuscus, in which the mean was 33.3 g/dL, without statistical differences between males and females (p ≥ 0.05).…”

“…As was mentioned, no statistical differences were found between sexes (p ≥ 0.05) (Table 3). Similarly, Barboza et al (2011) for the MCH found 135 pg (diet with 38 % of crude protein) and 130 pg (diet with 64 % of crude protein), results that are almost twice more than found in this study (Table 2). In the case of spectacled caiman, the MCH value of 63.49 pg (Carlos et al, 2017) was 10.49 pg lower than that found for Caiman crocodilus fuscus; nonetheless it is within the normal range that was determined for this species, which oscillates between 53.83 pg and 88.66 pg.…”

“…This comparison can be seen in Table 2, where a complete set of the data collected and provided by other authors and for other species of alligators is shown. (Barboza et al, 2011).…”

“…The typical hematological values for the Caiman latirostris were determined for Barboza et al (2011), who found that the hematocrit was 21 %, with a balanced diet and crude protein of 38 %. This value was 2.36 % less than that reported in this study (Table 2).…”
