Valorization of agro-alimentary waste for a production of maggots like source of proteins in the animal feeds

Abstract

An experimentation of production of maggots starting from agro-alimentary waste was led to the research station on the diversification of the pisciculture of the University of Abomey-Calavi (Benin). Seven substrates were used for the production: dejections of pigs (P), chicken viscera (V), and soybean oil cake (T) and their respective mixture dejections of pigs-chicken viscera (PV), dejections of pigs-soybean oil cake (PT), chicken viscera-soybean oil cake (VT) and chicken viscera-soybean oil cake-dejections of pigs (VTP). At the end of the experiment, the best productivities of maggots of 8.89 g.100g -1 and 7.20 g.100g -1 are respectively obtained with substrates VT and VTP. Low productivities of 2.62 and 3.20 g.100g -1 being obtained respectively with the dejections of pigs and the chicken viscera. It comes out from this study that the mixture of the soybean oil cake to the chicken viscera seems the best substrate having had a significant attractive effect on the flies and thus of productivity of maggots.
