Managing pests in animals

Animals eat off the ground, sniff backsides, and enjoy dirt and are therefore more likely to be targeted by parasites, inside and out, so the animal health industry has developed useful products for controlling ticks and worms in the gut. Examples are anthelmintics, which act against parasitic worms inside the animal, and ecto-paraciticides, which control parasites such as fleas hopping around the animal’s skin or fur. Anyone who has discovered fleas in their house will know how annoying they can be.

One of the ways to control pests is through vaccination. Animal vaccines build immunity to debilitating diseases such as blackleg, which literally turns a cow’s leg black, and scabby mouth, which causes painful sores on a sheep’s lips.

If an animal does get sick, antibiotics might be used to fight the bacterial infection by inhibiting its growth or by preventing it from reproducing. The animal health industry also makes products for veterinarians performing surgery.
