Nutritional supplements are a key element in promoting the health of poultry and livestock and enhancing their productivity, as they provide nutrients that may be insufficient in conventional feed. They support proper growth, strengthen immunity, and improve the quality of meat, milk, and eggs. These supplements include essential vitamins and minerals for metabolic processes, amino acids that contribute to muscle development and weight gain, as well as enzymes and yeasts that enhance digestion and improve feed utilization efficiency, and probiotics that support digestive health. Additionally, energy and protein compounds help improve milk production in livestock and increase animals’ ability to withstand environmental conditions. Balanced use of supplements helps reduce diseases, increase productivity, and achieve better performance of animals at all stages.
