Δ2-Doramectin is widely used in veterinary medicine as an antiparasitic agent, particularly effective against internal and external parasites in livestock. It is commonly administered to cattle, sheep, and pigs to control nematodes, mites, lice, and ticks. The compound works by disrupting the nervous system of parasites, leading to their paralysis and death. Its application helps improve animal health, productivity, and overall welfare by reducing the burden of parasitic infections. Additionally, it is often used in formulations for injectable solutions or pour-on treatments, providing convenient and long-lasting protection. Regular use supports sustainable farming practices by minimizing the impact of parasitic diseases on livestock.
