What class of compounds includes those used to control parasites in swine?

The correct response identifies anthelmintics as the class of compounds specifically designed for controlling parasitic infections in swine. Anthelmintics work by targeting and eliminating parasitic worms, which are common in livestock, including pigs. These compounds are crucial in maintaining animal health and productivity, as parasitic infections can lead to significant health issues, affecting growth and feed efficiency.

While insecticides are designed to manage insect pests, and systemics refers to a broader category of compounds that can affect various pests systemically, these do not specifically target the parasitic worms that anthelmintics do. Vermicides is a term that may describe agents that kill worms but is less commonly used in the context of veterinary medicine for swine compared to anthelmintics. Understanding the role of anthelmintics emphasizes their importance in livestock management and the overall health of swine.
