In goats, what other clinical sign may accompany the detection of Haemonchus contortus?

In goats, the detection of Haemonchus contortus, commonly referred to as the barber pole worm, often leads to decreased milk production as a significant clinical sign. This is primarily due to the impact of the parasite on the goat's overall health and condition. Haemonchus contortus causes significant blood loss through blood-feeding, which can lead to anemia. An anemic goat may not have the necessary nutritional reserves to maintain normal milk production levels.

When a goat experiences substantial parasitic burden, the body diverts energy and resources from non-essential functions like milk production to combat the infection and maintain vital functions. As a result, a drop in milk yield is frequently observed in lactating goats affected by this parasite. This can be particularly problematic in dairy goats, which rely on consistent milk production for economic viability.

Other clinical signs, such as noticeable weight gain or abdominal distension, may not apply to infected goats, as these animals often experience weight loss and a distended abdomen due to fluid accumulation in severe cases of parasitic infection. Prolonged drooling, while it can occur for various reasons in goats, is not specifically associated with Haemonchus contortus infection and does not carry the same direct implications for milk
