Abstract

Achatina fulica snails from two environments (Natural and Breeding) were subjected to two diets, one based on green fodder and the other based in the form of concentrate flour in order to evaluate linear growth. Thus, at the end of this study, we testify that Achatina fulica in the natural environment as well as in the breeding environment has a lower linear growth at the level of l/w; l/h relationship. Then, it grows less in width and height than in length. However, in terms of the height-width relationship, the linear growth is greater in the breeding environment than in the natural environment where Achatina fulica has a lower growth. With regard to weight growth, it should be testified that Achatina fulica generally gains less weight than it grows in length regardless of environment, either in natural environment or in breeding environment where snails are fed on concentrate.

Introduction

Snail farming is growing in sub-Saharan Africa. Its tender, tasty chair, very rich in proteins, in salts minerals and especially in iron, represents an alternative source of animal protein ((Zongo et al., 1990; Otchoumou et al., 2003a; 2003b; 2004a; 2004b; N’da et al., 2004). The species concerned are Achatina achatina, Archachatina ventricosa, Achatina fulica, Archachatina marginata, a species increasingly consumed in Côte d'Ivoire (Agongnikpo et al., 2010, Dosso et al 2007a, Dosso et al., 2007b). Research related to a snail crop focused on certain species. The choice of organic buying as a biological model for our Study is not for a star of giant snails, this species is consumed in parts of Nigeria, Togo, Liberia, Benin (Egonmwan, 1988; Edjidike et al., 2004; Fagbuaro et al., 2006) and Ivoiry coast.

But the pickup, consequence of an increasing demand, led to a reduction of the workforce (Stievenart and Hardouin, 1990). Thus, for its preservation, many researchers have contributed by studies to the development of purchase-farming by basing their work on breeding techniques (Upatham et al., 1988, Hodasi 1989, Hardouin et al., 1993), on nutrition (Ireland, 1991), on growth (Otchoumou et al., 2003b, Adou et al., 2011) only young adults. The success of production and especially the extension of the purchase of only by knowing the species of snails best suited to the conditions breeding, but also by controlling certain biotic and abiotic factors that directly influence their production. 

It is therefore necessary to continue research on key areas for improvement. It's about determining: 

1- the nutritional needs of spat for the purpose to improve their growth, to advance the age of maturity sexual

 2- To reduce the development cycle while associating a high productivity. For our part, we will focus on subjecting a concentrated feed to Achatina fulica spat in order to appreciate the effect of feeding on its biological performance in aboveground breeding.
