The chemical composition and body proportions of Achatina fulica (Bowdich), Achatina achatina (Linné) and Archachatina ventricosa (Gould) fed a concentrated diet were investigated and compared with wild A. fulica, A. achatina and Arch. ventricosa. Wild and artificially reared snail shell proportion were 42.09 and 46.91%; 47.20 and 52.96%; 48.02 and 51.96% of the whole body, respectively, for A. fulica, A. achatina and Arch. ventricosa. The pedal mass proportion was 41.36 and 36.66%; 27.80 and 26.62% than 36.59 and 32.71%, respectively, for wild and reared A. fulica, A. achatina and Arch. ventricosa. The pedal mass mean energy, dry matter, proteins, lipid and mineral matter content were 53.21cal/100g; 12.86% by weight of deshelled snails; 63.98/ DM (% of dry matter); 15.80/DM and 8.96/DM in A. achatina. For A. fulica pedal mass average energy, dry matter, proteins and mineral matter content were 47.82 cal/100 g; 13.63% by weight of deshelled snails; 58.94/DM and 14.92/DM. Arch. ventricosa pedal mass mean energy, dry matter, proteins, lipid and mineral matter content were 50.32 cal/100g; 14.19% in weight of deshelled snails; 66.36/DM; 13.43/DM and 10.25/DM. The protein contents differed slightly between artificially reared and wild snails.
