Lasalocid is primarily used as an antibiotic and coccidiostat in veterinary medicine, particularly in poultry and livestock. It helps prevent and control coccidiosis, a parasitic disease that affects the intestinal tract of animals. By inhibiting the growth of coccidia, it improves animal health and productivity. Additionally, lasalocid is used as a growth promoter in cattle, enhancing feed efficiency and weight gain. It is often incorporated into animal feed as an additive to ensure consistent intake. Its ionophoric properties also aid in improving nutrient absorption and overall animal performance.
