Com o objetivo de determinar a exigência de proteína bruta (PB) em dietas para o "escargot" francês (Helix aspersa maxima), 200 animais com peso inicial médio de 2,00 g foram distribuídos em um experimento inteiramente casualizado com quatro tratamentos [12,00; 15,00; 18,00 e 21,00% de PB] e cinco repetições, com 10 animais por unidade experimental, durante 90 dias. Foi observado efeito quadrático dos teores de PB sobre o peso final médio, a conversão alimentar, taxa de eficiência protéica, porcentagem de concha e rendimento de carcaça com os melhores valores nos teores de 16,23; 16,95; 14,79; 16,07 e 15,87% de PB, respectivamente. A taxa de sobrevivência não foi afetada pelos teores de PB utilizados. Concluiu-se que a exigência de PB em dietas para "escargot" francês é de 16,23%.Aiming to determinate the dietary crude protein (CP) requirements for Helix aspersa maxima snail, 200 animals, with average initial weight of 2.00 g were used, and assigned to a completely randomized design with four treatments [12.00, 15.00, 18.00, and 21.00% CP] and five replicates of 10 animals per experimental unit, during a period of 90 days. It was observed a quadratic effect of CP levels on final mean weight, feed conversion, protein efficiency rate, shell percentage and carcass yield with the best values for 16.23, 16.95, 14.79, 16.07, and 15.87% CP, respectively. The CP levels did not affect the survival rate. It may be concluded that the requirement of CP on diets for the Helix aspersa maxima is 16.23%.
