SNP profiles are obtained via a low density bovine SNP chip that includes the 200 SNPS from ISAG parentage panel as well as specific genetic defects and production traits currently under validation.
Parentage analysis and genetic defects/production SNPs are provided with the addition of a SNP genotype file (~7K SNPs).
The cattle XT Plus assay includes:
- Parentage assignment
- Report of single gene tests
- Client ownership of the SNP genotypes
- The genotypes made available to your provider of choice for genomic selection
- Storage of DNA for 18 months (long-term storage option also available)
- Database storage of genotypes
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 sell them to you.
Ear punch is our recommended sample type. We are still able to process semen and hair samples but a surcharge will apply.
We welcome the opportunity to discuss our cattle genotyping service with you to suit your requirements.
