Abstract Background This study aims to investigate the reproduction output of Archachatina marginata fed on roughage and concentrate feed with leaf meal-inclusive diets. One hundred fifty points of lay snails weighing between 150 and 170 g were randomly allotted to 5 treatment diets with three replicates, ten snails per replicate, designated as treatment 2 (GNCD) which has groundnut cake, treatment 3 (GLLM) has Gliricidia sepium, treatment 4 (MOLM) has Moringa oleifera, and treatment 5 (LLLM) has Leucaena leucocephala leaf meals as protein source in snail diet and a control (treatment 1) (UPWP) fed on roughage (unripe pawpaw and watermelon peel) in a 12-week feed trial. Feed intake, weight gain, egg lay, egg fertility, hatchability, and gonadosomatic index were measured.Results The result revealed snails fed with UPWP had the least final weight and weight gain which was accompanied by the highest feed intake across the treatments. Average egg laid, hatchability, fertility, embryo mortality, and average juvenile produced by snails on roughage-based diet were significantly the least across the treatments. High gonadosomatic index of snails on leaf meal-based diet accompanied with better reproductive output in laying snails was recorded.Conclusion Snails fed with Leucaena leucocephala-inclusive diet had better egg production, fertility, hatchability, and juvenile snails accompanied with gonadosomatic index across the treatments. Concentrate ration is essential for optimal reproductive output in snails.
