RESUMO

The terrestrial snails belong to the families Achatinidae (Africa) and Helicidae (Europe). The most known species is the Achatina fulica (Giant African), being the most recommended for the tropical and subtropical regions due its capacity of adaptation to these climates. Mucus of terrestrial snails Achatina sp has been searched had its wound healing activity, beyond the antibacterial activity. The suplementation (plants with defined wound healing purposes as comfrey, papain and centella asiatic in the rations of these animals) had the intention to characterize the glycoprotein composition of mucus, considering well-being of the animal, since the same ones had not been sacrificed. Using a methodology holding the collection through manual stimulation of the podal, responsible gland for the secretion of mucus. This methodology is divergent of some authors who had used electric stimulation with electric current on the animals for the collection of mucus, method contrary to the intentions of animal well-being. This study, beyond using a less drastic and harmful methodology to the animals, allowing that the same ones returned to its own creation environment. The analyses carried through for color and spectroscopy tests, evidenced that the alterations presented in the tests had been very similar; however, showed a significant variation in the glycoproteic composition of the analysed mucus.
