Abstract

The aim of this study was to determine the appropriate amount of dietary calcium to reduce the impact of density on laying performance in Achatina fulica. To do this, 1380 breeding animals were divided into 8 batches reared at different densities. For each rearing density, the breeding stock were classified into 4 sub-lots and fed diets differing in their calcium content. The reproductive performance of these breeders was determined and compared as a function of rearing density and dietary calcium level. The results showed that for a diet with a low calcium source content (10%), the density above 25 breeders per square metre led to a significant drop in the laying rate (13 ± 3.7% to 9.36 ± 4.13%) and the number of eggs per clutch (111.23 eggs/clutch to 98 eggs/clutch). However, for a diet with a high calcium source content (40%), the rearing density had virtually no impact on the reproductive performance of Achatina fulica. This study shows that, in order to make his facilities profitable, the farmer can place 40 breeders per square metre of rearing enclosure, provided that their feed contains sufficient calcium (40% oyster shell).
