The article highlights the recent approval of processed animal proteins (PAPs) for use in pig feed, including products like meat, bones, feathers, and blood that were previously rejected for human consumption. This move is aimed at reducing CO2 emissions and improving animal health. However, the use of these animal protein-rich products is not widely accepted in all sales markets, especially in Great Britain. The Sustainable Pork Chain is promoting broad acceptance of these raw materials while advising pig farmers to ensure their feed does not contain poultry meal and to consult with their feed suppliers if it does.
