Alternativas sustentáveis na produção de suínos

The use of corn, rice and soybean co-products is an alternative to a production with greater sustainability and better economic viability. An alternative proposes the use of isolated enzymes, or complexes of enzymes, and with the use of these enzymes in the diet that there are ingredients that are co-products, it is supposed to improve the digestibility and reduce the emission of pollutants present in the swine feces. Industrial swine farming, characterized by containment systems with large population densities, results in the production and accumulation of large amounts of residues in pig farms that, inadequately managed, have come to be considered as one of the main polluting sources. However, there are now several ways to reuse these wastes in a sustainable way. Examples are: decantation basins and the use of biodigesters, being this second option with a great cost benefit for the pig farmer. In view of the above, this review aims to address sustainable practices that are an option for pig producers to provide an economically viable and ecologically correct product
