I finally bit the bullet and ordered the DNA test kits from the APHA the other day. I will be testing both my mares for HERDA, HYPP, GBED, and OLWS. I will also be sending in separate samples for PSSM1, as the APHA panel does not cover it. That's the part I'm nervous about.
The part that's exciting is that I also ordered the color test panel! Yay. This test will cover red factor, agouti, cream, pearl, champagne, dun, silver, gray, tobiano, OLWS, Sabino1, and SW1, 2 & 3. My mares aren't canidates for many of these, but it's cheaper to do this than order separately and I think they list the results on the registration papers, which is pretty cool. :p
Anyway, wish me all negatives on the genetic disorder panel!
