Available for Merinos only
The Sheep Horn Poll test provides an opportunity for Merino breeders to identify polled or horned sires and dams to speed up progress towards a purely poll flock.
Selection of homozygous polled animals, versus phenotypically polled animals, increases the proportion of polled progeny from a particular mating, which in turn increases the speed of transition from a horned to polled Merino flock.
The Sheep Horn Poll test was developed by the Sheep CRC using measurements on animals in the Information Nucleus Flocks and data from the 50K SNP chip. Research has validated the test in the Merino breed, however, results are unable to be guaranteed in other breeds.
Sheep breeders ordering either the Sheep Parentage test or the GGP Ovine 50K will receive results for the Poll test at no additional cost.
Identification of poll gene only requires sampling individuals of interest. In most situations, this involves sampling only the rams and possibly some ewes being selected for a breeding program.

- Once your samples are mailed, estimate 7-10 business days before samples arrive at the lab. The DNA is processed and DNA results are then read by our data service team and reported to you.
- Be sure to allow yourself and our team enough time if you are needing results by a specified date.
Using Allflex TSUs have several benefits including:
- Quick and easy sample collection at any any.
- Receive more data from a single sample, which can be stored for future testing or multiple tests.
- Users must ensure that their RFID equipment is correctly configured for scanning TSU sample codes.
Tips for DNA TSU sampling
- Be sure that if the animal has been freshly tattooed that all ink is avoided in the sample.
- If sampling a newborn lamb, be sure to wipe the ear clean so that no DNA is transferred from the dam.
- Be sure that there is tissue within the TSU before releasing the animal, and that the tissue is submerged in the buffer.
- TSUs can be stored for up to one year at room temperature.
Remember to note which sample belongs to which animal, and check with your breed association for their specific DNA collection process. Contact your Local Neogen Territory Manager or Customer Service for assistance or questions about Allflex TSUs and genomic testing solutions.
The Turnaround Time (TAT) depends on various factors, such as the time it takes for your sample to reach our laboratory in Queensland, sample type(s) whether it is TSU samples or blood samples and whether the test results are reported directly or to your breed society.
Please keep in mind that if we need to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.
