Noodle waste (NW) (a by-product from wheat noodle processing industry) which attract little cost was used to replace maize fraction of the diet of snail in order to reduce feed cost. A total of 120 adult snails (Archachatina marginata) of mean weight 173.42 ± 3.5g of about 9 months of age were used for the feeding trial. Four diets were formulated to contain NW at 0% (A1 ) Control, 50% (A2), 75% (A3) and 100% (A4) as replacement for maize fraction in the diet of adult snails. Completely randomized design was used for the trial and each treatment was replicated thrice with 10 snails per replicate. The diets were formulated to
contain about 24% crude protein and energy of 2400 kcal/kgME. Data were collected on intake, weight gain, shell length, thickness and width, feed efficiency, feed conversion ratio, dressing percentage, feed cost and cost per weight gain. Results showed that no significant differences were observed in the mean feed intake, weight gain and feed conversion ratio (P>0.05). The dressing percent of the snails was relatively the same in all the treatments (P>0.05). The results of cost analysis showed that cost /kg feed and total feed cost reduced as the level of NW in the diet increased. It was concluded that NW could replace
maize fraction of the diet at reduced cost .
