Main Internal Parasites Affecting Sheep and Goats: An Overview

Sheep and goats can be affected by several internal parasites. In this article, we will provide an overview of the main internal parasites commonly found in these animals.

  1. Haemonchus contortus (Barber's Pole Worm):

Haemonchus contortus is a parasite that affects the abomasum, causing anemia, weight loss, and mortality.

  1. Teladorsagia circumcincta (Brown Stomach Worm):

Teladorsagia circumcincta targets the abomasum, leading to diarrhea, reduced weight gain, and compromised health.

  1. Trichostrongylus spp. (Black Scour Worm):

Trichostrongylus spp. infest the small intestine, causing diarrhea, weight loss, and reduced productivity.

  1. Cooperia spp. (Small Intestinal Worm):

Cooperia spp. primarily affect the small intestine, resulting in diarrhea and reduced weight gain.

  1. Nematodirus spp. (Thin-Necked Intestinal Worm):

Nematodirus spp. infest the small intestine, causing diarrhea, dehydration, and stunted growth, particularly in young animals.

  1. Strongyloides spp. (Threadworm):

Strongyloides spp. infect the small intestine, leading to issues like diarrhea and poor growth, especially in young animals.

  1. Fasciola hepatica (Liver Fluke):

Fasciola hepatica infestations, known as liver fluke, can damage the liver and impact productivity. Sheep are more susceptible, but goats can also be affected.

Conclusion:

Sheep and goats are prone to various internal parasites, including Haemonchus contortus, Teladorsagia circumcincta, Trichostrongylus spp., Cooperia spp., Nematodirus spp., Strongyloides spp., and Fasciola hepatica. Understanding these parasites is crucial for effective parasite management. Regular monitoring, targeted deworming, proper pasture management, and good husbandry practices are essential for minimizing the negative effects on the health and productivity of these animals. Seek advice from a veterinarian or livestock professional for guidance tailored to your specific flock or herd.
