Innovative on-farm technology to produce improved feed: an agroecological approach

Abstract : Background: Worldwide demand for meat, milk is projected to increase by 57 % and 48%, respectively, between 2005 and 2050. More than 70% of the livestock farming cost is allocated for feed. However, climate change requires a systemic approach to feed research. A paradigm shift has to occur within a wider food system context with an agroecological approach to optimise the interactions between plants, animals, humans and the environment for a sustainable and equitable food system. Thus, farmers are faced with the challenge of feeding livestock with low-cost feed of good nutritional and sanitary quality and with a low environmental footprint. Approach: This review makes an inventory and critical analysis of technologies to conserve and/or improve the quality of feed available on mixed crop-livestock farms in a frugal economy approach. We focused on biomass available on farm especially co-products, unsold crop and crop residues. Agroecological impacts technologies were discussed so as to determine great strategies to feed livestock. Conclusions: Agro-industrial technologies can be used, to preserve feed, to improve feed value of ingredients for livestock from various by-products and so enhance animal performance and feed preservation. However, lack of knowledge, labour and investment limit the adoption of these strategies. Frugal technologies are suitable on farm for their appropriation by smallholders. Consequently, participatory approaches are required to provide and promote adoption of these innovations on-farm.
