Description

Many livestock and aquaculture feeds with food output for resources. This rivalry could be reduced by increasing the use of food system byproducts and residues as feed. They collected information on global food system material flows for crop, livestock, and aquaculture production, with an emphasis on feed use and the availability of byproducts and residues. They investigated the feasibility of substituting food-competing feedstuffs-in this case, cereals, whole fish, vegetable oils, and pulses, which account for 15% of total feed use-with food system byproducts and residues.

Taking into consideration the nutritional needs of nutrition living creatures, including cultivated aquatic species, this swap could increase the world's food supply by up to 13% in terms of total kcal and 15% in terms of protein content. Increasing the use of food system side products as feed has enormous potential in the desperately needed transformation to cyclical food production, particularly when combined with the other initiatives. Because a large percentage of the resources used in livestock and aquaculture feeds could be eaten by humans, the present structure of the global food system results in suboptimal food availability. Animal feeds consume up to 40% of all arable land and more than 30% of cereal crop production, and approximately 23% of all captured fish is intended for non-food uses, primarily fish and livestock feeds. Because arable land is used for animal feed production rather than directly adding to human consumption, this food-feed competition reduces the efficiency of the current food system.

Increasing feed use of food system by-products, secondary products produced alongside primary, human-consumable products, has been suggested as a solution to increase resource use efficiency, reduce food-feed competition, and increase food system circularity. Furthermore, using food system byproducts as feed can decrease environmental strain on arable land and freshwater ecosystems, as well as greenhouse gas emissions and fertilizer application. Increasing the use of byproducts and crop residues as feed can also save money because many of them are readily accessible and inexpensive. Some non-food competing feedstuffs, however, are less appropriate for feed use; for example, crop residues are fibrous and have low digestibility and protein quality, whereas others, such as some crop processing byproducts, are protein dense but low in energy. Some non-food competing feedstuffs, on the other hand, can be enhanced through processing or additives. Despite the difficulties, some food-competing feedstuffs could be replaced with non-foodcompeting feedstuffs without affecting productivity.

In this study, they look at the possibility of increasing the use of food system byproducts and residues in animal feeds to improve circularity in the global food system. This method offers a muchneeded systemic view of the highly interconnected global food system and advances research on three major fronts. First, there are no worldwide datasets at this level of depth that include both feed material flows and the availability of food system byproducts and residues. While various models and reports provide statistics on livestock or aquaculture feed use, this information is not consistent across the global food system. Furthermore, although some studies have approximated feed use both in agricultural and fish farming systems, they either fail to login for regional differences in feed use or place an emphasis on a specific region. They combined and harmonized data from various sources, including crop, cattle, and fish farming output, as well as wild fish stocks, and measured the dynamics of global feed flows in unprecedented detail.

Even though some by-products or residues have potential availability that is much greater than their present use as feed, animal-specific nutritional requirements limit their use in livestock and aquaculture diets. For instance, even though crop residues are plentiful, their inclusion potential in diets that sustain animal productivity is limited by their fibrousness, absence of protein, and easily utilizable carbohydrates. The same holds true for some other feed ingredients. For instance, livestock by-products could take the place of all fish consumption, but not all fish oil in aqua feeds can be changed to processed animal fats from livestock in order to preserve the essential fatty acid profile needed for aquaculture output.
