Name one common parasite that affects livestock.

Internal worms are a common parasite that affects livestock, and they can significantly impact the health and productivity of animals. These worms, which can include species such as roundworms and tapeworms, live in the gastrointestinal tract of the host and feed on nutrients that the animal consumes. This can lead to malnutrition, weight loss, reduced growth rates, and even death in severe infestations.

Managing internal worms is crucial in livestock management, as they can also lead to secondary infections and complications if left untreated. Farmers and livestock owners often implement deworming strategies and good hygiene practices to control these parasites and maintain animal health.

While ticks, fleas, and ear mites also affect livestock, internal worms are particularly noteworthy due to their prevalence and the broad range of negative effects they have on livestock health and productivity.
