Tilbroquinol is primarily used in veterinary medicine as an antiparasitic agent. It is effective against a range of intestinal parasites in animals, particularly in livestock and poultry. The compound works by disrupting the metabolism of the parasites, leading to their elimination from the host's body. It is often administered in feed or water to ensure easy consumption by the animals. Tilbroquinol helps in maintaining the health and productivity of livestock by preventing parasitic infections that can lead to weight loss, reduced growth rates, and other health issues. Its use is crucial in ensuring the overall well-being of animals in agricultural settings.
