| If there was a stallion that was a carrier for glycogen branching enzyme deficiency (GBED) would you still breed to him if he was out of a producing dam and sire? Also if he was a true 1D horse? Would that affect your decision to pick another stallion?

Location: Peg-Leg Julia Grimm | GBED is recessive. If I wanted to breed to a GBED positive stallion, I would test my mare. If she's negative for GBED, it's all good. But the fact of the matter is, everyone should test all their mares for at least the 5 panel. There are other things that need to be bred away from as well. And it's not just the stallions fault. |

| That’s what I thought both have to be carriers for it to show! Thank you for your input! |

| But is it responsible to breed to a carrier and risk carrying the disease further another generation? Plus I think even if the resulting foal is only a carrier of a recesive disease, resale value will be reduced. |

| No one seemed to mind with A Smooth Guy and he was a carrier of two not just one. |

Are a smooth guy foals reduced? |

For the last few weeks I've been seriously shopping for a stud prospect. I priced several 2 yo prospects out of well bred mothers. I passed on 2 prospects by A Smooth Guy because they were not 5 panel N/N even though 1 had the strongest dam of all of the prospects I was looking at. They were cheaper and I still passed. Is that a perfect example since the prospects were not exactly the same in every other way? No. But it was certainly a major part of my decision. |

Yeah I understand that! Especially if you’re looking for a stallion prospect! |

| If you had a young stallion that was a carrier would you cut him or give him a chance? |

In my opinion absolutely not. Im happy the 5 panel is becoming requested and people are seeking clean horses but I have no issues breeding recessive carriers to clean partners.
If we were to just say K, nobody who caries a recessive genetic disorder can no longer breed the genetic pool would be drastically reduced, many believe to a dangerous level, I would have to agree to be honest.
If breed properly to foal has a 50/50 chance of being a carrier or clean, I just do 5 panel results with parentage DNA and the new owners can make any informed decisions they want with all the info to breed safely if they so chose to.
If you want only 5 panel clean stock that is OK too, but It does not lower the price to me and I have breed to a GBED carrier before and its been my highest selling foals to date. |

| I must live under a rock or something because I can only think of 2 commercial studs that are GBED carriers. I don't think either of them add so much to AQHA that anyone would even notice if they weren't part of the yearly breeding decisions.

Location: Peg-Leg Julia Grimm | It sucks to be someone looking for a stallion prospect at this time.
But compared to the next 5 disorders and the 5 or 10 after them, GBED is NOTHING! Give me a GBED horse over a P2 horse any day and all day.
Whether you believe in the P2 variant testing or not, there are at least 30 more muscle myopathy diseases lurking in our stock. Per Dr. Valberg. Some day they will be able to test for them. Very few people will have clean horses and one copy of GBED will look like a blessing if that's all they have. Thing is there are a lot of "dirty" horses competing now. A lot of them are by some of the highest priced stallions in our industry and many are on their way to the NFR or have been there. So... There's a lot to think about. |

I had the pleasure of attending a weekend conference hosted by Dr. Valberg. Her knowledge is incredible. |

There are more than 2 ...
Then consider HERDA.
Then consider all the mares
My filly was sold before I even got her results back, they did not care one way or another what they were.
I used to be dead set against any genetic diseases but I have changed my opinion quite strongly after lots of research and hearing to lectures on the matter. The real issue is all these mares that are NOT tested where proper informed breeding decisions can not be made without all the information.
However its your money your are spending, spend it how you see fit.... Nothing wrong with 5 panel clean, don't take me that way but I don't run away from recessive carriers either. |
