The higher density tests GGP-50K and GGP uLD-30K provide parentage and are also used in the genetic evaluation to add accuracy and information to the calculated EPD. The Parentage Panels do not provide this benefit, other than ensuring that the pedigree is correct. AI sires, Herdsires and ET Donors require a GGP 50K test. The uLD panel is best suited for cattle that are well connected to the Simmental population and are not entering seedstock herds.
If you are only interested in parentage on a calf a Basic SNP or Parentage Plus panel can be ordered. While this will sort out parentage it does not provide any further information to the genetic evaluation about the animal being tested.
- Is this animal an AI Sire, Herdsire or ET Donor? Order a GGP 50K - $45
2. Will this animal have a large impact on my herd? Order a GGP 50K - $45
3. Do I want to test for other traits such as Horned/Polled, Homo Black?
Order a GGP 50K with Additional Traits as Required
50K, Horned/Polled $55
50K, Coat Colour Homo Black $50
50K, Coat Colour Dilutor $50
50K, Horn/Poll, Homo Black $60
50K, Horn/Poll, Dilutor $60
4. Is this animal a unique pedigree or out-cross to the mainstream population?
Order a GGP 50K - $45
5. Do I want additional EPD accuracy and confirmation of parentage without needing additional trait information?
Order GGP uLD 30K- $35
6. only require parentage confirmation?
Order Basic or Parentage Plus Panel- $20
In most cases the additional investment in the GGP uLD 30K or GGP 50K panel is warranted. These panels provide all of the parentage information and contribute to the EPD evaluation. The GGP 50K tests when paired with specific trait tests are also a cost effective way to obtain specific trait information and enhance the EPD of the animals and are cheaper in combination than performing a standalone trait test and then requiring a 50K or parentage at a later date.
Genetic Evaluation - Impact of GGP 50K on genetic evaluation
While it is essential to continue to collect and record trait information, the following table shows the equivalent number of progeny required to boost the EPD accuracy the same amount that a GGP 50K test does.
