Name a common parasite affecting goats.

Haemonchus contortus, commonly known as the barber pole worm, is a significant parasite affecting goats. This nematode is primarily known for causing anemia and weight loss in infected animals due to its feeding on blood in the host's stomach. Goats tend to be particularly vulnerable to infestations of this worm, especially in warm, humid climates where the parasites thrive.

The life cycle of Haemonchus contortus allows it to reproduce quickly, and its larvae can survive in the environment to infect naïve goats. This makes control and prevention measures critical in goat management practices. Effective management often involves regular monitoring of fecal egg counts, strategic deworming, and maintaining a clean living environment for the goats to minimize exposure to the larvae.

While other parasites such as Coccidia, Toxoplasma, and roundworms also affect goats, Haemonchus contortus stands out due to its severe impact on the overall health and productivity of the animal, making it one of the most critical parasites to manage in goat herds.
