The performance of African giant land snails (Archachatina marginata) fed ripe eggplant fruits was studied using eighty-four (84) juvenile (four months old) Archachatina marginata for eight (8) weeks. The study evaluated the snails' growth performance and lipid profile (total cholesterol, low-density lipoprotein, high-density lipoprotein and triglycerides). The snails were divided into four treatment groups, with twenty-one (21) snails per group in a completely randomized design (CRD). Treatments 1, 2, 3 and 4 had varying levels of ripe eggplant fruits at 0%, 5%, 10% and 15% inclusion levels respectively. Isocaloric and isonitrogenous feeds and water were provided ad libitum, while other management practices were strictly adhered to. The results showed no significant differences (P>0.05) in growth performance across treatments. The results also revealed that total cholesterol decreased (P<0.05) significantly as the levels of ripe eggplant fruits increased across treatments. There were no significant differences (P>0.05) in low-density lipoprotein and triglycerides, while high-density lipoprotein differed (P<0.05) significantly across treatments. The result also showed a linear increase in high-density lipoprotein ("good" cholesterol) as the levels of ripe eggplant fruits increased across treatments. Therefore, a 15% inclusion level of ripe eggplant fruits in the diet of Archachatina marginata reduces total cholesterol levels and increases high-density lipoprotein without any adverse effect on growth. The study recommends using ripe eggplant fruits to formulate diets for animals with high cholesterol content and high levels of low-density lipoprotein in their meat.
