Proteins play a fundamental role in animal nutrition. However, when their supply is unbalanced, excess excretion of nitrogenous compounds occurs, leading to economic losses and causing environmental impact due to contamination of soils and water sources. The production of enteric methane by ruminants has also come into the focus of environmental discussions, which has put pressure on the search for dietary strategies aimed at reducing the environmental impacts of animal production, seeking maximum performance and profitability in livestock farming.
