Want to genotype your animal today? Complete the Genotyping Request Form now.
Since genotyping became available with its introduction in 2009, over the past three years, several testing options have been made available mainly for purposes of obtaining genomic enhanced breeding values. Recently, genomic testing has become a cost effective option to confirm or discover parentage for national herdbook purposes in addition to increasing the accuracy of genetic evaluation.
The Association should be informed of the need for parentage testing in situations where doubt may exist in regards to the parentage of a calf. Parentage verification requests will be sent to the owner, in situations where there is doubt as to the parentage, and lineage of a Holstein animal. It is important that owners use the forms provided to identify the animals being tested, and that these forms accompany the hair samples to Holstein Canada.
Microsatellite versus Genomics
Standardized testing is required for parentage verification to support Herdbook integrity. A microsatellite request can be upgraded to LD, LD plus, or 50K testing for national purposes. Request microsatellite if genetics (semen/embryo/animal) are being exported. Microsatellite will continue to be required until iSAG approval and international acceptance on SNP parentage panel.
GenoID is a genomic (DNA) testing service available to Holstein breeders to discover parentage and provide a genetic evaluation. Genetic evaluations form the basis for many herd improvement decisions and accelerating genetic progress. GenoID will automatically register animals in the Holstein Canada Herdbook.
What information do you need to supply with the GenoID application?
Producers must first have a prefix and account setup with Holstein Canada. In order to get the full benefits of GenoID, information such as: NLID/ATQ tag number, herd management number and date of birth are required. See the GenoID application form below for a complete listing of information needed.Geno ID Application
What are the benefits of GenoID?
- One step process for genotyping and registering animals with accuracy
- Provides a genomic and genetic evaluation
- Better understand the genetic potential of animals in the herd
- Ability to rank animals on genetic merit
- Optimize mating decisions to accelerate genetic progress
- Accurate way to manage inbreeding
- A tool to select, market or cull animals
How does it work?
- Producers need to complete a GenoID application form for each animal being tested. A DNA sample (tail hair or swab) should be collected from the animal and submitted for genotyping.
- The DNA samples are first inspected by Holstein Canada to help ensure there will be enough tissue for the laboratory process. Samples may still fail at the laboratory due to poor DNA quality and/or insufficient quantity.
- You will be contacted by Holstein Canada staff if there are any concerns.
- The process generally takes 4-6 weeks from the time the sample is received at Holstein Canada.
