Physicochemical characterization of a feed based on food waste for broilers and organic chickens

Abstract

The city of Oujda has a very significant production of solid waste that annually exceeds 340,000 tons, of which the organic fraction represents at least 70%. In order to promote the recovery of solid organic waste, a study was carried out on an alternative food made from food waste (FW) in the city of Oujda (Morocco). Before being applied on different flocks of chickens (industrial broilers and farmer broilers), this Lab-Prepared Feed was analysed to determine its organo-mineral composition in comparison to other composed poultry feeds that are marketed in Morocco. The results of organo-mineral characterization showed a composition of 13% in total nitrogen, 7% in mineral matter and 4% in fat, while for the composed poultry feeds, these components were 15%, 6% and 5%, respectively. The composition of nutriment found for the studied materials may promote the food waste recovery to be used as a raw material of the Lab-Prepared Feed (LPF). Thus, it may enable to replace, under sustainable view, the composed poultry feeds, which have presently become very expensive due to various economic factors.
