Since December 2017, NZ Herefords breeders have been able to Single Nucleotide Polymorphism (SNP) DNA test animals with recently 100K SNP tests being avaialble at Neogen.
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.
NZ Herefords strongly recommend you use Neogen, located in Australia, as your service provider. PBB hold a contract with Negoen and Neogen very early on verified their SNP DNA test for NZ Herefords genetic defects and provide a DNA profile.
To break down the SNP DNA process for NEOGEN orders, NZH 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?
Click here for a Neogen Hereford genotype application form
Step 3 – Results - receiving and interpretating 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 or Zoetis) and the parents by another eg Neogen, then services of Helical (Theta) and PBB need to be sourced at an additional charge.
Single Step BREEDPLAN heralds a new age in genetic evaluation technology available to the beef cattle industry. This new genetic analysis combines pedigree, performance and genomic (DNA) information together in a complete multi-trait BREEDPLAN analysis of birth, growth, fertility, carcase and feed intake traits. Genomic information now contributes to the Estimated Breeding Values and accuracy calculations of genotyped animals and their relatives.
Single Step BREEDPLAN is genetic analysis software developed by the Animal Genetics and Breeding Unit (AGBU), a joint venture of NSW Department of Primary Industries and the University of New England, which receives funding for this purpose from Meat and Livestock Australia Limited. The single step analysis utilises pedigree, performance and genomic information simultaneously. The analysis takes account of each animal’s actual genetic relationship based on its genotype with all other genotyped animals, including those in the reference population. The reference population is the set of Hereford animals within the Hereford BREEDPLAN analysis that have both genotypes (SNP data) and phenotypes (performance records) for a particular trait.
