Abstract: The effect of 25% crude protein diet, green papaw (Carica papaya) leaves or 25% crude protein diet plus green papaw (Carica papaya) leaves (ratio 1:1) on African giant land snail (Archachatina marginata) growth performance and survival were studied for over 180 days. The study diet treatments were designated treatment I-III, respectively. The Archachatina marginata were stocked five snails per replicates of nine for the three treatments in wooden cages raised 10 cm above the ground and fed 2% body weight day ¹. The Archachatina marginata fed on treatments 1 and 11 had similar (p>0.05) body weight gain. The body weight gain of Archachatina marginata fed on treatment 111 was significantly influenced (p< 0.05) more than those on the treatments I and II. The morphological parameters (shell, length, shell width, shell aperture) followed the same trend of significance as body weight.
