Part of modern day animal breeding is the assessment of the production value of livestock by using Estimated Breeding Value (EBVs). Selection of breeding animals with superior EBVs in growth rate, egg, meat, milk, or wool production, or other desirable traits has revolutionized livestock production throughout the world. Commonly, EBVs are calculated using statistics such as best linear unbiased prediction.
In recent years, genetic data based on DNA has been added to the EBV calculations. Phenotypical traits have been related to segments of DNA, making the genetic data a predictive model for the performance of an animal. These so-called genomic EBVs are indicated as genomic EBVs or gEBVs.
VHLGenetics is now able to offer the statistical calculations needed to generate gEBVs through its partner the American organization Council of Dairy Cattle Breeding (CDCB). This test allows for the assessment (calculations) of US-based gEBVs, commonly known as GTPI.
Test specific information
The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.
The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.
Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.
