Abstract :In this study, the effect of eggshell added to the diet as a calcium source on the growth performance of juvenile land snails (Cornu aspersum) was evaluated. In the study, 3 experimental diets were prepared using eggshells added to the diets in two different ways: with (ES) and without (MES) membrane with limestone (LMS). Experimental diets were prepared as isonitrogenous (~15%), isolipidic (~3%) and isocalcium (~13%). The experiment was conducted for 45 days and the growth rates of the snails were monitored by interim weighing at 15-day intervals. At the end of the experiment, the best growth, weight gain and SGR were determined in the group fed with membrane eggshell supplemented diet (P<0.05). FCR was better in the eggshell groups (ES and MES) than in the limestone supplemented group. No mortality occurred in any group during the study period. According to the results of the study, it is thought that eggshell can be added to the diet of juvenile land snails as a calcium source and recycling of waste eggshells will benefit the environment and economy.
