Fecals, They Matter

Deworming should not be a guessing game. A goat can look rough for many reasons: nutrition, stress, weather, pregnancy, nursing kids, age, illness, mineral imbalance, or internal parasites. While experience and observation matter, a fecal test gives you information you cannot see from the outside.

A fecal egg count checks a manure sample for parasite eggs. It can help show whether internal parasites are part of the problem and give you a better idea of what is happening in the herd. It does not replace good observation, but it adds an important layer of information. Fecals matter because they help goat owners avoid two common mistakes:

• Treating when treatment is not needed.
• Not treating when treatment is needed.

Both can hurt the herd.

Overuse of dewormers can contribute to drug resistance. Underdosing, wrong product choice, or repeated treatment without knowing whether the product still works can also create problems. On the other side, waiting too long to treat a truly parasitized goat can lead to anemia, weight loss, bottle jaw, weakness, poor growth, poor milk production, and even death. Fecals are especially helpful when used with other information, such as:

• • FAMACHA score
  • Five Point Check
  • body condition
  • weight gain or weight loss
  • coat quality
  • diarrhea or manure changes
  • age and stress level
  • pregnancy or lactation status
  • pasture and weather conditions
  • herd history
  • previous response to dewormers

A single fecal result is useful, but patterns are even more useful. Over time, fecals can help you learn which animals are more parasite-resistant, which animals repeatedly struggle, which pastures are higher risk, and whether your management program is working.

Fecals can also help identify whether a dewormer is still effective on your farm. A fecal egg count reduction test compares fecal counts before and after treatment. This can help show whether a dewormer is reducing parasite egg counts the way it should.  This is important because parasite resistance is common in goats. Once resistance develops, a dewormer may no longer work well in that herd, even if it worked years ago or still works somewhere else.

The goal is not to run a fecal every time a goat sneezes. The goal is to use fecals as one tool in a thoughtful parasite-control program. Good parasite management is not just about what bottle is on the shelf. It is about knowing your herd, watching individual animals, using dewormers carefully, protecting refugia, avoiding unnecessary treatment, and learning what works on your farm.

A calculator can help with dose math.

A fecal helps you understand whether deworming is needed and whether the treatment is working.

Both have their place.
