Sabino Pinto Test
A DNA test for Sabino is now
available at all three labs shown above. This test will be very helpful
in establishing if a horse carries the sabino gene. While this test does not
test for all the possible sabino genes, it is the first sabino test that has
ever been available and tests for the Sabino (SB1) gene. All that is needed
is a pulled hair sample sent to the lab.
We were fortunate to be included in the
University of Kentucky sabino research in 2004 and submitted twelve samples
to the research. Examples of horses that tested positive for the sabino gene
can be seen on our website. This is a new exciting test for miniature horse
owners that are interested in positively identifying another pinto pattern.
Horses that are homozygous for sabino (sb1)
are completely white at birth, and could be confused as cremellos, though
genetic testing would correctly identify them as sabinos. Sabinos can have
dark or blue eyes. Lethal white foals are also completely white at birth,
but die within hours or days. These lethal white foals can only occur when
two frame (LWO) horses are bred together. Lethal foals can be avoided by
testing the horses before they are bred to determine if they carry the
lethal white gene.
