Emu DNA Sexing Test

Male or female? Let the DNA decide!

Determining the sex of an emu can be difficult when relying on appearance alone, especially in young birds. Our Emu DNA Sexing Test provides a genetic method for determining the sex of your emu from a small DNA-containing sample.

Whether you're raising emus for breeding, building a breeding program, managing a growing flock, or simply want to know what you've got, DNA sexing can give you valuable information for planning ahead.

What Does This Test Tell You?

Emus have a genetic sex determination system that allows their sex to be identified through DNA testing.

This test analyzes the submitted DNA sample to determine whether the emu is genetically male or genetically female.

DNA sexing can be particularly useful for young emus, where physical characteristics may not provide a reliable indication of sex.

1 Test = 1 Emu

Each purchase includes one DNA sexing test for one emu.

If you have multiple emus, please purchase one test for each bird.

Every sample must be clearly identified so that results can be matched to the correct emu.

Instructions for DNA Sexing

Materials Needed
1) Sharp, sterilized nail clippers
2) Antiseptic or disinfectant (e.g., alcohol wipes)
3) Sterile gauze or cotton balls
4) Styptic powder or cornstarch (to stop bleeding if needed)
5) Gloves

**For sample collection, you may use paper, coffee filters, Q-tips or cotton swabs.

Preparation
1) Wash your hands thoroughly and wear gloves to prevent cross contamination
2) Gently restrain the chick, holding its foot securely without squeezing too hard.
3) Select a toenail—typically a clear or light-colored nail helps for visibility.
Clipping & Blood Collection
1) Sterilize the nail clippers using an alcohol wipe or disinfectant. Repeat this
between each chick to prevent cross contamination.
2) Clip the tip of the toenail carefully—cut only enough to begin light bleeding of the
quick, avoiding cutting too deep to prevent excessive bleeding.
3) Allow a small droplet of blood to form at the nail tip.
4) Quickly transfer the blood to your collection form of choice—lightly press the chick’s toenail against the collection material, ensuring a clean drop sample.
5) If bleeding continues, apply styptic powder or cornstarch to stop it.
6) Clean the toenail area with antiseptic to prevent infection.

Tips and tricks for a high quality sample:
-Dry the Samples – Lay freshly collected samples flat in a ventilated area for at least 2-4 hours, ensuring no direct heat or sunlight.
-Label Clearly – Use a fine-tip permanent marker to add chick ID, date, and any
necessary details without touching the blood spots.
-Store Safely – Place each fully dried sample in a separate Ziploc bag, remove excess
air, and keep in a cool, dry place for safekeeping.
-Once dry, pack up into an envelope and mail standard USPS. If overweight for
multiple samples, it may have to be shipped flat rate mailer.
