LDHA Gene Discussion
Is there a commercial test currently available in the U.S. where one can
submit samples to be analyzed for the LDHA gene? Yes there is. This lab has
already conducted LDHA genotyping on racing pigeons and is set up to perform
this analysis on a commercial basis. It is as follows:
Gene Check, 1175 58th Ave., Suite 100, Greeley, Colorado 80634
Toll Free Phone 800/822-6740 Website: www.genecheck.com
This lab is headed by Dr. Bob Wagner where his team has performed primarily
livestock genotyping for over 17 years and has analyzed over 40,000 sheep
samples during that time. Dr Wagner is available to answer in depth questions
that you may have concerning LDHA genotyping.
What is the approximate cost for a LDHA test? Cost will be $20.00 per
sample/bird and if there are submissions of large numbers of samples, quantity
discounts will be available.
How do I collect and submit a sample? This is quite simple. DNA can be
extracted from a pigeonís feather, so this makes collection extremely easy. A
single feather from the secondary flights is probably the desired
feather/sample, as they are shorter than the primaries to enclose in a sample
envelope. The small gummed envelopes of the 2 ľ X 3 Ĺ inch or 3 X 4 Ĺ inch size
are ideal to place the feather sample in. Seal the envelope and be sure to label
the envelope with the birdís band number. The small collection envelopes can
then be consolidated into a larger mailing envelope, for sending to the lab. A
collection form can be printed from the Gene Check website to accompany samples.
In what ways will the LDHA test be utilized by the sport? One loft races
where stamina is essential in hot conditions with headwinds such as the South
Africa race, could be a likely choice in analyzing for and sending only AB or AA
genotypes. Pigeons selected for and sent to other one loft series may also be
analyzed and selected with the beneficial AB or AA genotype in trying to
increase their odds in these races.
Elite seed stock producers who look for ways of differentiating themselves from
the competition may also utilize LDHA genotyping. Pigeons with the AB and AA
genotypes will most likely be in higher demand and bring higher prices as others
incorporate this technology into their breeding schemes.
Over time smaller lofts may want to identify the genotypes of their key breeders
and breed for an increased frequency of the A allele in their breeding stock.
Are their any negatives? There is the possibility that as the A allele
becomes favored, dumping of well bred breeders that test BB onto the internet
sale sites to unsuspecting buyers could take place. Also, donít abandon the
pigeons that have brought you success. LDHA is only a tool, and cannot replace
homing ability, quick orientation, and the desire and determination to get home.
