Crystal of hemoglobin in capybaras (Hydrochaeris hidrochaeris) blood and its skillful importance

Abstract

The aim of this work was to select a method for animal identification, supplying important subsidies to characterize or not of crime as much as slaughter of wild animals as tortures of domestic ones, both protected by law, as well as verify the crystallization of the hemoglobin, precisely oxihemoglobin, in blood ‘in nature’ with anticoagulant and coagulate in capybaras. Preparations modified by Costa were used in this work. This technique has a low cost of implementation, it is fast to obtain results and it is easy to prepare and handle. After the compilation and data analysis, it was verified the amount, size, color, site and the contour of the crystal are not associated with the sex of animal; also, the amount of the crystal depends on the applied technique, where the technique 2 (fresh blood oxalate is spinet, the sediment is lacqued with saporin; sulfate of sodium is added and mix it up energetically during 10 minutes at speed 4) the one that yelled more crystals, bigger crystals intense coloration (pink intense) and regularly distributed in the blade.
