Choosing the Right Sheep Dewormer Comparison: Oral vs Injectable
Share

Keeping your sheep healthy and productive starts with an effective parasite control program. But with so many products available — drenches, injectables, and combination treatments — how do you know which option is right for your flock?
In this post, we’ll break down the differences between oral and injectable dewormers, their advantages, and when to use each one.
Why Deworming Matters
Internal parasites like roundworms, wireworms, and tapeworms can cause poor growth, weight loss, and even death in sheep. Regular deworming helps maintain herd health, improves feed conversion, and ensures better lambing performance.
However, using the right product at the right time is just as important as dosing itself.
1. Oral Dewormers (Drenches)
Common forms: Liquid drenches or pastes given by mouth.
Examples: Prodose Orange, Nem-A-Rid Orange, Kombidose 4 or 3
Advantages:
- Easy to administer in groups
- Fast action against stomach and intestinal worms
- Wide variety available for different parasites
- Ideal for routine dosing and lambs
⚠️ Considerations:
- Must be dosed accurately by weight
- Can be spat out if not administered correctly
Best for: Routine parasite control, especially during lambing and weaning seasons.
2. Injectable Dewormers
Common forms: Injectable solutions given under the skin or in the muscle.
Examples: Ecomectin, Closeco
Advantages:
- Longer protection period
- Also effective against external parasites (ticks, mites, lice)
- Easier for small groups or individual treatments
- Great for high parasite challenge areas
⚠️ Considerations:
- Requires needles and proper technique
Best for: Heavier parasite burdens, external parasite control, and individual handling.
