Since December 2017, NZHA breeders have been able to Single Nucleotide Polymorphism (SNP) DNA test animals by using either 10K SNP test at Genomnz or 50K SNP tests at Neogen (previously known as GeneSeek).
The benefit of SNP testing over microsatellite testing is largely resulting in increased accuracy and genomic prediction. If you wish to read more about the benefits of genomic testing, click here.
Choosing which test best suits your farming operations, dictates which service provider to choose and thus what form your sample needs to be.
The current choices of service providers which have verified their SNP DNA test for NZHA genetic defects and provide a DNA profile include:
To break down the SNP DNA process, NZHA and PBB have broken this into 3 Steps:
Step 1 – What Test? - Which Test do I want and thus which service provider do I choose? (see below infographic. Click to view a larger version)
Step 2 – The Process - How do I take a sample and submit it?
NOTE process steps 4-6 in the below infographic are only relevant for samples to be sent to Neogen. If you are sending samples to Genomnz, please follow the guidelines under Genomnz https://herefords.co.nz/genomnz.html
Step 3 – Results - receiving and interpretation the results.
If sires or dams of the progeny have been SNP tested at Neogen, then sire or parent verification can be requested on the Neogen application form as part of the Hereford bundle and inclusive of the cost.
In the circumstance where progeny has been tested by one service provider (eg Genomnz) and the parents by another eg Neogen, then services of TREE (Theta) and PBB need to be sourced at an additional charge.
