Emission Reduction in Poultry Production Begins with Nutrition

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.
