Pregnant Mare Serum Gonadotropin (PMSG) is a powerful hormone used in goat breeding to induce superovulation and synchronize estrus cycles. However, administering the correct PMSG dosage for goats is critical to achieving optimal results. Too little PMSG may yield poor ovulation rates, while too much can lead to ovarian hyperstimulation. In this guide, we’ll provide detailed dosage charts, tips for administration, and insights to help you maximize your breeding success.
Why Use PMSG for Goat Breeding?
PMSG, also known as Equine Chorionic Gonadotropin (eCG), mimics the activity of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). It is widely used to:
- Induce superovulation: Increase the number of eggs released during estrus.
- Synchronize estrus cycles: Align breeding schedules for efficient kidding.
- Enhance conception rates: Improve fertility, especially during off-season breeding.
For goat breeders, PMSG is a cost-effective way to boost productivity and profitability.
PMSG Dosage for Goats: Key Factors
The correct PMSG dosage depends on several factors, including:
- Breed: Larger breeds (e.g., Boer goats) may require higher doses than smaller breeds (e.g., Nigerian Dwarfs).
- Age and Weight: Mature, heavier goats typically need higher doses than younger or lighter ones.
- Breeding Goals: Superovulation protocols often require higher doses than estrus synchronization.
- Season: Off-season breeding may necessitate slightly higher doses to overcome natural hormonal imbalances.
PMSG Dosage Charts for Goats
Below are general dosage guidelines for common goat breeding scenarios. Always consult a veterinarian for precise recommendations.
1. Estrus Synchronization
| Goat Type | PMSG Dosage (IU) | Timing |
|---|---|---|
| Nigerian Dwarf | 200–300 IU | 48 hours before breeding |
| Boer Goat | 300–400 IU | 48 hours before breeding |
| Alpine/Saanen | 250–350 IU | 48 hours before breeding |
2. Superovulation
| Goat Type | PMSG Dosage (IU) | Timing |
|---|---|---|
| Nigerian Dwarf | 400–500 IU | 5 days before breeding |
| Boer Goat | 500–600 IU | 5 days before breeding |
| Alpine/Saanen | 450–550 IU | 5 days before breeding |
3. Off-Season Breeding
| Goat Type | PMSG Dosage (IU) | Timing |
|---|---|---|
| Nigerian Dwarf | 250–350 IU | 48 hours before breeding |
| Boer Goat | 350–450 IU | 48 hours before breeding |
| Alpine/Saanen | 300–400 IU | 48 hours before breeding |
How to Administer PMSG to Goats
Step 1: Prepare the PMSG Solution
- Check the Dosage: Determine the required dose based on the charts above.
- Reconstitute the Hormone: If using powdered PMSG, mix it with sterile water or saline as per instructions.
- Draw the Solution: Use a sterile syringe to draw the correct amount of PMSG.
Step 2: Prepare the Goat
- Restrain the Goat: Use a headgate or halter to keep the goat still.
- Disinfect the Injection Site: Clean the neck or thigh area with an alcohol swab.
Step 3: Administer the Injection
- Subcutaneous (SC) Injection:
- Pinch a fold of skin on the neck or thigh.
- Insert the needle at a 45-degree angle and inject the PMSG.
- Intramuscular (IM) Injection:
- Insert the needle straight into the muscle (thigh or neck).
- Inject the PMSG slowly to minimize discomfort.
Step 4: Monitor the Goat
- Observe for Reactions: Watch for swelling, redness, or allergic reactions.
- Track Estrus Signs: Monitor for behavioral changes indicating heat (e.g., restlessness, mounting).

Frequently Asked Questions
Q: How long does PMSG take to work in goats?
A: Estrus typically occurs within 48–72 hours after injection.
Q: Can I reuse syringes and needles?
A: No, always use sterile, single-use equipment to prevent contamination.
Q: What if my goat shows adverse reactions?
A: Contact a veterinarian immediately. Adverse reactions are rare but can occur with improper administration.
