Deer Genotyping

We are now able to offer precise genomic relationships, breed composition and level of inbreeding for every animal as well as parentage analysis.

With the advancement of technology, we have begun using ear punches as our primary sample type. These samples are stored in Tissue Sampling Units (TSUs) and are taken on farm by using an applicator to punch a small piece of tissue from the animal’s ear directly into the sampling unit. This sample type has been shown to provide both higher quality DNA and potential on-farm benefits.

The Allflex® TSUs and applicator (where licensing allows) can be bought directly from your local farm supply store as a separate unit or (if you use Allflex tags) can be bought with the tag order allowing the TSU to be linked to the tag, and remove the need for any manual recording. Alternatively, GenomNZ is more than happy to supply them.

We welcome the opportunity to discuss our deer genotyping service with you to suit your requirements.

Genotyping using GBS offers:

Immediately

• High throughput reliable parentage testing
• Breed composition
• Genomic relationships
• Level of inbreeding

Medium term

• Genomic breeding values
• Lethal and desirable variants

Long term

• Genomic tools developed specifically for accurate selection for robust, high yielding NZ deer

At Invermay we are developing a research herd recording difficult to measure traits that are commercially important. We are concentrating our efforts on immune function and disease and parasite resistance in deer. The program is called Tomorrows Deer and the aim is to identify the best genetics for robust healthy deer that perform well. As part of this work we are using the new markers to scan the genome for genes with large effects on health and production in order to identify the best animals.

When enough data is collected Deer breeders will be able to access molecular breeding values for the same cost as parentage. This is a major step forward with the potential to accelerate genetic gain and increase performance. Genetics shouldn’t just be about production though, how well the animal fits into the farm system is equally as important. Our job at Invermay is to work with the farm systems team to breed an animal that is productive, healthy and fits into the modern deer farming environment.
