    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract It is widely recognized that the food system generates a broad range of environmental impacts and that the contribution of livestock is significant. For these and other reasons, the future role of animals in the food system is heavily debated. A central question is: what role, if any, could animals play in an environmentally sustainable food system? We demonstrate that animals raised under the circular economy concept could provide a significant, non-negligible part of our daily nutrient needs. We suggest that the role of animals in the food system should be centred on converting biomass that we cannot or do not want to eat into valuable products, such as nutrient-dense food (meat, milk, and eggs) and manure. By converting these leftover streams, livestock recycle nutrients back into the food system that otherwise would have been lost in food production. The availability of these biomass streams for livestock then determines a boundary for livestock production and consumption. We argue, therefore, that we should no longer focus on improving life-time productivity of animals, but on improving the efficiency with which animals recycle biomass unsuited for direct human consumption back into the food system. Future research, therefore, should be directed at questions, such as: which combination of animal systems (including insects and fish) convert available biomass streams most efficiency? Or, which technological or biological treatments can improve the safety, digestibility and nutrient availability of biomass streams available for animals? Acknowledging this recycling role of animals in the food system also offers potential to account for other functions livestock provide to humans and to produce with respect for the animal. It however also implies that developed countries have to significantly reduce their consumption of animal-source food.
