Key words: blood, packed cell volume, hemoglobin, hemoglobinometer, Anseriformes, Columbiformes, Falconiformes, Galliformes, Passeriformes, Psittaciformes, Sphenisciformes, Strigiformes, Phoenicopteriformes, avian
Furthermore, the intercepts associated with the regressions for 8 of the 9 avian orders tested were not significantly different (P > .05) from zero, but the intercept associated with the regression for Phoenicopteriformes was significantly different (P < .01) from zero at +6.69.
With the possible exception of Phoenicopteriformes, a single intercept can also be used for all avian orders.
On the basis of the Findings of this study, Phoenicopteriformes might have a different relationship between Hgb and PCV, with a lower linear regression slope (0.217) and larger intercept (+6.692) compared with those determined for the other 8 orders evaluated.
