, low in fat (0.05-0.08%) and contains almost all the amino acids needed for human nutrition. The effect of different level of <i>Gmelina arborea</i> leaf meal (GALM) and enzymes supplementation on the growth characteristics of Juvenile land snail (<i>Archachatina marginata</i>) was investigated in a Completely Randomized Design (CRD) which lasted for ten weeks. Three levels of GALM (0, 25 and 50%) and two supplementation levels (no enzyme, enzymes supplementation) were studied. A total of two hundred and seventy (270) juvenile snails were used for the experiment with six diets, three replicates and fifteen animals per replicate. Final body weight (g) recorded were 101.64g, 96.90g, 89.18g, 95.32g and 96.50g for 0, 25, and 50% GALM inclusions, no supplement and enzymes supplement respectively. The result indicated that rate of gain (g/day) and daily fed intake (g) decreased consistently with increase in level of GALM, while supplementation with enzymes increased the rate of gain and daily feed intake. It was observed that up to 25% level of GALM level inclusion pose no harm to the growth and development of juvenile snail. Therefore, up to 25% GALM inclusion level in snails diet is recommended and in the same vein enzyme supplementation in the diets of snails should be encouraged since it improves growth characteristics.&picture=http://www.aascit.org/aascit/decorators/img/journal/907.jpg)

Nigeria continues to experience animal protein shortages for human consumption due to many challenges facing the livestock industry. Snails as a member of the livestock group constitute an important source of animal protein which can take care of this shortfall if feeding and other management practices are properly addressed. It contains about 18-20% protein in wet weight basis, high iron content of (45-59mg/kg), low in fat (0.05-0.08%) and contains almost all the amino acids needed for human nutrition. The effect of different level of Gmelina arborea leaf meal (GALM) and enzymes supplementation on the growth characteristics of Juvenile land snail (Archachatina marginata) was investigated in a Completely Randomized Design (CRD) which lasted for ten weeks.

The result indicated that rate of gain (g/day) and daily fed intake (g) decreased consistently with increase in level of GALM, while supplementation with enzymes increased the rate of gain and daily feed intake. It was observed that up to 25% level of GALM level inclusion pose no harm to the growth and development of juvenile snail. Therefore, up to 25% GALM inclusion level in snails diet is recommended and in the same vein enzyme supplementation in the diets of snails should be encouraged since it improves growth characteristics.
