Show Notes

Have you ever heard someone talk about parasite resistance in goats, only to have someone else start talking about dewormer resistance? Although they sound similar, they're describing completely different things.

In this first official Goat Note, Deborah explains three concepts that every goat owner should understand:

1. Parasite resistance – A goat's ability to limit the number of parasites living inside its body.
2. Parasite resilience – A goat's ability to stay healthy and productive despite carrying a parasite burden.
3. Dewormer resistance – The worms' ability to survive treatment with a deworming medication.

Understanding the difference isn't just about using the right terminology. These concepts affect breeding decisions, parasite management, and how we preserve the effectiveness of the dewormers we still have available.

In this episode, you'll learn:

1. Why parasite resistance and resilience are not the same thing
2. How parasite-resistant goats help reduce pasture contamination
3. Why resilient goats can still shed large numbers of parasite eggs
4. Why dewormer resistance is a problem with the parasites—not the goats
5. How confusing these terms can lead to poor management decisions

Goat Note Takeaway

Parasite resistance and parasite resilience are traits of the goat. Dewormer resistance is a trait of the worms.

Once you understand that distinction, many of the recommendations you hear about breeding, parasite control, and selective deworming become much easier to understand.
