Unique partnership brings breakthrough genomic tool to commercial sheep breeders
DNA Collections
.webp)
DNA collection is a fundamental part of modern breeding programs, supporting genomic testing for parentage verification, trait analysis and breeding values.
When samples are collected correctly, they provide reliable genetic information that helps breeders make informed decisions and meet breed society and industry requirements.
Weatherbys Scientific enables breeders to collect DNA samples on-farm using approved methods that are practical and scientifically robust. Each collection option is designed to maintain sample integrity from the point of collection through to laboratory analysis, ensuring consistent, high-quality results.
Several DNA sampling methods are available, depending on species, management practices, and testing requirements. Tissue Sampling Units (TSUs) are the preferred method for livestock, offering a fast, hygienic, and highly reliable approach to DNA collection. Alternative options, including hair and semen sampling, are also available where appropriate.

Order your Allflex Tissue Sampling Units (TSUs) and applicators directly from Weatherbys.
Step 2: Submit your form
Email your Sample Submission form to hello@weatherbys.com.au and ensure you include where you would like your data reported and the format required. We will work with any third-party Evaluation Centre of your choosing.
Step 3: Post your samples
Collect your samples and submit them by posting to PO Box 6493, Clifford Gardens, Qld 4350. Ensure your name and contact number are on the parcel.
Step 4: Await confirmation
Receive your sample receipt notification from our Customer Service Team – cs@weatherbys.com.au. Our lab will perform quality checks, genotyping and subsequent data analysis and will notify you if there are any issues with the samples.
Step 5: Receive your results
Results are delivered to the nominated Share File, Breed Society and/or Evaluation Centre nominated at the time of submission. If you have requested breeding values from an Evaluation Centre, they will be in touch with you directly.
Step 6: Expect your invoice
Your invoice will be sent to your registered email address.
Top tips for Tissue Sampling
During the sampling process
Ensure the animal’s ears are free from contamination. This is particularly important for newborn calves to avoid any transfer of DNA from the dam.
Ensure the TSUs are clean.
Avoid using sanitisers, soaps or disinfectants near the sampling site before taking the TSU as this will degrade the DNA in the sample.
Check there is minimal blood in the sample and avoid other contamination where possible
Make sure the red stopper is all the way in the sampling unit and has sealed to prevent liquid leaks and oxygen getting into the sample.
Post sampling care and transport instructions
Store samples at or below room temperature, in a cool, dry, dark place.
Avoid extreme temperatures including hot cars and freezers.
Send TSUs in a padded envelope or box to prevent damage during transport.

Do you process hair samples?
Yes, hair samples are accepted for DNA testing. Please note that additional processing is required for hair samples, and this is reflected in an additional fee. Contact us for more information and to order hair card collection kits.
Do you process semen samples?
Yes, we can process semen samples for DNA testing. Please note that specialised processing is required, and this is reflected in an additional fee. Contact us for more information.
How to ship a semen samples?
Please submit whole semen straws for testing. Weatherbys will only accept unused straws.
We recommend allowing the straw to thaw in the fridge after removing it from liquid nitrogen before shipping.
To prevent breakage during transit, please place the straws in empty pen barrels (or similar) with a couple of ice bricks. The semen does not need to arrive to us frozen, the ice helps to reduce exposure to high temperatures and DNA degradation.
