ABSTRACT
Although often considered as a single group of chemicals, veterinary medicines are a diverse group of different products containing a broad range of compounds belonging to different chemical classes and used for a diverse assortment of conditions (see Table 2.1 in Chapter 2). Antiparasiticides control external parasites such as ticks or sea lice (ectoparasiticides), internal parasites such as gastrointestinal worms and protozoans (endoparasiticides), or both (endectocides). Antibiotics are used for the treatment and prevention of bacterial infections, whereas fungicides are administered to treat fungal or yeast infestation. Hormones regulate growth, reproduction, and other bodily functions.
