Emission reduction in poultry production is essential for sustainable livestock farming. Precision nutrition optimizes nutrient supply according to animal requirements, reducing nutrient waste and improving efficiency. Low-protein diets supplemented with amino acids can lower ammonia emissions by around 10% for each 1% reduction in crude protein. Feed additives such as Ecobiol® and GuanAMINO® further improve feed efficiency, animal health, and resource utilization, reducing CO₂ emissions by up to 7%. Combined with digital formulation tools, these strategies provide an effective and practical approach to more sustainable poultry production.
