A copy of this hair sampling information is also availabe for download.
How to sample
- Take the sample from the top of the rump (deer), bottom of the tail switch (cattle), or, if this does not work, try the mane
- Ensure the sample area is clean
- Pull the hairs out firmly in a smooth upward motion (against the direction of growth)
- the hair follicle must be present, live and intact
- do not cut the hair from the rump
- dead or broken hairs (flattened) are not suitable
- avoid sampling a moulting animal or an area where shedding is occurring
- For cattle, trim the sample in order to remove any excess faecal material but make sure you leave the follicles attached
- Place the hair in the Genomnz paper envelope provided (see below)
The follicle at the end of the hair shaft contains the DNA used for analysis in the laboratory.

Avoid Contamination
- Remove any loose hair from the sample area prior to sampling
- Wipe any stray hairs from you hands before you sample each animal
- Trim to remove faecal matter (cattle)
- If using a crush, ensure there is no hair stuck to the sides
- Do not collect samples if the animals are being shaved for TB test (deer)
