dc.description.abstractThe effects of feeding diets containing three different calcium sources limestone (LM), eggshell (EG) and seashell ((i.e., shells of marine molluscs; SS) on proximate, fatty acid and amino acid composition and nutritional quality indices of edible land snails (Cornu aspersum M & uuml;ller, 1774) are evaluated. Higher levels of monounsaturated fatty acids (MUFA) and a higher DHA/EPA ratio were found in the snail meat of the SS group. Snail meat in the LM and EG groups contained higher levels of saturated fatty acids (SFA) and n-3 fatty acids. Although the fatty acid distribution was more balanced in the EG group, it had a lower n-3 PUFA ratio than the other groups. However, the higher h/H ratio and lower PI value in the SS group indicates that this diet may have a negative effect on meat lipid quality. The EG diet has a high EAA content and a balanced EAA/NEAA ratio, the LM group provided a more balanced amino acid profile and the highest EAA/NEAA ratio was found in snails. Our study shows that choice of calcium source may influence the nutritional properties of Cornu aspersum, with eggshells being a sustainable and effective bio-calcium source for food production.
