    EFFECT OF SOME PLANT-FOOD MATERIALS ON THE GROWTH RATE OF THE AFRICAN GIANT LAND SNAIL (ARCHACHATINA MARGINATA)

    Adeparusi, E. Oluwayemisi and E.A. Agbelusi1

    There has been an increase in the quest for the optimal production of the African giant land snail (Archachatina marginata) under culture. In this study we assessed the growth response of this snail to locally available food materials: Talinum triangulare leaves, Carica papaya leaves, Boerhavia diffusa leaves and Colocasia esculenta leaves.

    Three growth parameters were measured: weight, body length and aperture length. Data on these growth parameters were collected biweekly. The rate of growth in body weight was found to be affected by the type of diet while the body length and aperture length were found to be independent of type of diets. The highest growth rate of 0.30 gm per day was recorded in snails fed with pawpaw leaves, this differed significantly ( P < 0.01 ) form the growth rate on Talinum leaves which had a lower growth rate of 0.10 gm per day.

    Keywords: Plant-food, Body length, Aperture length.
