Evaluación del Comportamiento Productivo y Reproductivo y Reproductivo de Caracoles (Helix aspersal9. Criados en Parques de Engorde.

Abstract

In the parish La Matriz, Guano canton, Chimborazo province, the productive and reproductive behavior of snails (Helix aspersa) raised at fattening parks in 210 days investigation was evaluated analyzing different reproductive and productive variables in a population of 100 reproducers and a 381 -snail sample for the growth and fattening stages (30-180 days). At the end of the investigation it has been determined that the Helix aspersa snails at the reproductive stage presented 20.05+3.91g body weight, while the number of eggs per laying reached 91.04+5.59 units with a birth time of 21 days and 1.52+0.50 layings per year. After the escargot stage they presented a final weight of 2.68+0.92g and a concentrate conversion of 1.44+0.54. After the fattening stage the snails presented a final weight of 15.55+0.97g with a concentrate conversion of 2.39+0.10 and a harvest time of 23.3 weeks, with a benefit-cost index of 1.31 USD. This is why it is recommended to use and transfer the results of the present investigation through linking programs as a basis for the implementation of production and reproduction parks of Helix aspersa.
