Two hundred and twenty-five snails Achatina fulica (Bowdich, 1720), of approximately three days old, were subjected to two diets made up of green fodder (R1 and R2) and three concentrated floured diets (R3, R4 and R5) with variable contents of proteins [10,5% (R3);14% (R4) and 17,5% (R5) ], during 50 weeks in breeding.This work aims at studying the effect of the diet and its content of proteins on the growth of this snail, in captivity.The diet R1 consists of Lactuca sativa (Asteraceae), Carica papaya (Caricaceae), Brassica oleracea (Brassicaceae), Cecropia peltata (Moraceae), Laportea aestuans (Urticaceae) and Phaulopsis falcisepala (Acanthaceae).n addition to the sheets used for the diet R1, the diet R2, is added with sheets of Leucena leucocephala (Fabaceae-Mimosoideae), a plant relatively rich in proteins.The growth and the survivals rates of snails subjected to the concentrated floured diet rich in protein were definitely better than those subjected to the diets made up of green fodder relatively low in protein. The weight growth improved with the increase of the content of proteins of concentrated diet. Thus, the best live weight (198,62 g) is presented by snails subjected to R5 follow-up by that obtained with R4 (178,50 g). The vegetable diet R2 containing the sheets of L leucocephala caused the most mortality.The survival rate of A. fulica knew an improvement with the increase in the rate of proteins of the concentrated diets.

Abstract: (french)
Deux cent vingt-cinq escargots Achatina fulica (Bowdich, 1720), âgés d'environ trois jours, ont été soumis à deux régimes constitués de fourrages verts (R1 et R2) et trois régimes concentrés de farines (R3, R4 et R5) avec des teneurs en protéines variables [10,5% (R3); 14% (R4) et 17,5% (R5)], pendant 50 semaines en milieu expérimental. Ce travail vise à étudier l'effet du régime et de la teneur en protéines alimentaires sur la croissance de cet escargot, en captivité. Le régime R1 est constitué de Lactuca sativa (Asteraceae), de Carica papaya (Caricaceae), Brassica oleracea (Brassicaceae), de Cecropia peltata (Moraceae), Laportea aestuans (Urticaceae) et de Phaulopsis falcisepala (Acanthaceae). Le régime R2, en plus des feuilles utilisées pour le régime R1, est additionné de feuilles de Leucena leucocephala (Fabaceae-Mimosoideae), une plante relativement riche en protéines. Les croissances pondérale et coquillière ainsi que les taux de survies des escargots soumis aux régimes concentrés riches en protéine ont été nettement meilleures que ceux soumis aux régimes végétaux, relativement pauvres en protéines. La croissance pondérale s'est améliorée avec l'augmentation de la teneur en protéines de l'aliment concentré. Ainsi, le meilleur poids vif (198,62 g) est présenté par les escargots soumis au régime R5, suivi par celui obtenu avec le régime R4 (178,50 g). Le régime végétal R2 contenant les feuilles de L. leucocephala à un taux de 37,78%, a causé le plus de mortalité. Le taux de survie de A. fulica a connu une amélioration avec l'accroissement de la teneur en protéines du régime alimentaire concentré.
