The effects of adding medicinal plants with healing properties (Centelha asiatica, Papaína and Confrei) in the control diet of land snails were studied to evaluate the effect of these plants on the mucus glicoproteic composition. Eighty Achatina sp snails, based on a homogeneous weight (49 and 40 g and averaging 10 and 19 months of age for Achatina fulica and Achatina monochromatica, respectively). The animals were randomly allotted to eight experimental groups: Achatina fulica (FC) and Achatina monochromatica (MC) control, Asian Achatina fulica (FCe) and Achatina monochromatica (MCe) centelha, Achatina fulica (FPa) and Achatina monochromatica (MPa) papaína and Achatina fulica (FCo) and Achatina monochromatica (MCo) confrei. Ration and water were fed ad libitum. At the end of 150 days of treatment, the animals were submitted to the technique for extraction of mucus glicoproteic by manual stimulation of podal gland, responsible for the secretion of this mucus. This methodology considered the well-being of the animals since they were not slaughtered but returned to their creation system. The mucus was analyzed by means of color and spectroscopic tests, that indicated similar changes, but showed significant variation in their glicoproteic composition.
