The use of anthelmintics in swine rations is specifically aimed at controlling internal parasites, such as worms. Anthelmintics are a class of medications designed to kill or inhibit the growth of these parasites in the gastrointestinal tract of animals. By utilizing anthelmintics, producers can effectively reduce the burden of internal parasites, which can lead to improved health, growth rates, and overall productivity in swine.

In contrast, while probiotics, enzymes, and antibiotics serve important roles in animal nutrition and health, they do not specifically target internal parasites. Probiotics are beneficial microorganisms that help promote gut health, enzymes assist with nutrient digestion, and antibiotics are used to combat bacterial infections rather than parasitic infestations. Therefore, the distinct action of anthelmintics makes them the appropriate choice for controlling internal parasites in swine.
