Types of Samples
We accept hair, blood, semen, and buccal swab 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

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 microsatelites 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.
