POTENTIAL AVAILABILITY OF MANGO BY-PRODUCTS IN THE BOBO-DIOULASSO AND ORODARA AREAS OF BURKINA FASO: ASSESSMENT OF THE QUANTITIES OF MANGO BY-PRODUCTS AND MANGO FEED PRODUCIBLE FOR RUMINANTS

The aim of the study was to assess the potential availability of mango by-products in Bobo-Dioulasso and Orodara, with a view to scaling up technologies for their valorization into animal feed. To this end, a cross-sectional survey was conducted among 24 drying units and 17 mango producers. The potential quantities of mango by-products and feed that could be produced were calculated. The results show that the potential quantities of mango by-products in the area were 7,857t for the units surveyed and 16,180t for those in operation. The potential quantities of feed that could be produced with these by-products were 4,190t and 8,427t for the surveyed and functional drying units respectively. Cumulative losses from orchards and drying units amounted to 38,994t, and the potential mango feed that could be produced was 19,486t. The potential nutritional supply from these feeds was 18,792t of dry matter (DM), 1,438t of digestible nitrogenous matter (DNM) and 21,547 UFFV. The surveys showed that mango processing and production by-products are available in the study area. Work is needed to scale up technologies for converting mango by-products into feeds that could be used for fattening. This would create added value for the mango sector, while increasing the availability of feed for animal production.
