The contribution of animal production to environmental pollution is a pressing global issue. This study aims to evaluate the chemical composition of selected feeds and explore the relationship between feed composition and pollutant emissions generated by animals. Chemical analyses of 10 feed samples assessed parameters such as protein, cellulose, fat, and nitrogen-free extractive contents. The goal was to identify some connection with pollutant emissions and propose nutritional strategies to reduce emissions, improve nutrient utilisation, and promote the sustainable management of animal resources. The results revealed potential links between feed composition and different emissions from animals with considerable environmental impact. High-protein feeds were associated with elevated nitrogen residues, while feeds with greater digestibility showed potential for reduced pollutant emissions. Future efforts should focus on adjusting feed composition and integrating optimised feed formulations to support a sustainable approach to animal nutrition, and reducing pollution from livestock production systems, benefiting both the environment and public health.
