Types of Samples
We accept hair, blood and semen samples. For hair samples, there must be at least 30-60 hairs with attached bulbs. This means the hair samples must be pulled, not cut. If you have trouble pulling a good hair sample, there are many videos and pictures for references.

Information about Genotyping
For cattle and horse genotyping and horse ancestry testing you will receive a general report which show the microsatellite markers for the individual. This is a unique, genetic finger print that can be used for identification. In cattle, each individual has two microsatellite numbers. One comes from the sire and the other comes from the dam. This is how we verify parents. The numbers (Ex: 202/208) represent the molecular weight of the DNA fragments and the markers (INRA23) typically represent the laboratory who founded the markers.
In equine ancestry, instead of numbers the microsatellites are represented in letter. The basic principles are exactly the same, only the letter is a part of a code which represents the particular fragment of DNA.
