Influência de diferentes dietas sobre o crescimento, sobrevivência e reprodução de Leptinaria unilamellata (d´Orbigny, 1835) (Gastropoda, Subulinidae) em laboratório

Resumo

To increase the knowledge on the biology of L. unilamellata in laboratory conditions, they were studied and analyzed the following parameters: influence of the diet on the growth of the shell, the mortality coefficient and reproduction. Five diet groups were established, each one with 20 specimens of L. unilamellata, these groups were separate in two classes: simple diet and combined diet. Simple diet: Group I (ration for birds in growth); Group II (ration for quails in posture beginning) and Group III (vegetables); combined diet: Group IV (ration for birds in growth + vegetables) and Group V (ration for quails in posture beginning + vegetables). The diet composed of ration for quails in initial posture, when offered separately made possible a larger growth of the shells of the snails and, when offered combined with vegetables, propitiated the smallest mortality coefficient and the largest production of descendants.
