This document addresses ammonia (NH₃) emission reduction in pig farming through dietary strategies, specifically lowering crude protein levels in feed while supplementing with amino acids. This technique effectively reduces nitrogen excretion and NH₃ emissions, while improving pigs’ daily weight gain and feed conversion efficiency. Cost savings are achieved by reducing the need for expensive protein sources like soybean meal. A proposed regulation suggests subsidies of 2 EUR per pig as an incentive for farmers. The strategy aligns with EU and Croatian environmental policy goals, aiming to increase pork production while reducing environmental impact.
