I lost a colt this week that was born with what the vet told me was likely a "blind pouch". Can anyone shed some light on the cause of this? is it likely my mare will always produce foals with this problem or is it unlikely to occur again? Also, I was told it equated to a "lethal white" scenario, again, I've never heard of this and would like to hear from anyone who has experience with it. Thanks, Ev |

I'm guessing your vet was using a lay term for "atresia coli". A search for that term plus "lethal white" on Google will yield explanations. |

Hi Ev ,
As Jos mentioned your colt likely had or what is referred to as Lethal White Syndrome , which occure's when you bred two Positive (Overo) Horses for OLWS togther , it can and has run in some lines of Qh and Breeding Stock horses with Overo's in thier pedigree !
If your mare has had one white foal her chances are 25 % that when bred to another Positive stallion to have another "Lethal" That does not mean your mare will ever produce another one but those are the chances , I currently stand a OLWS stallion and he is bred to only NEGITIVE mares in order to avoid having any lethals in the Future , If you want there is a company that will test your stock for the Gene and you can make your own decisions from there weather or not you wanna take a chance in getting another lethal .
I have tons of information and details on this color defect if your interested in learning more  Personally just because your mare has had one Lethal foal that would NOT stop me from breeding her again
Good luck and sorry you had to deal with this first hand , its very hard to wait 11 months only to lose a foal to something that could have been prevented .

Virginia or Jos - Ev's foal wasn't white, it was a bay. Can more than lethal whites have the "atresia coli" condition? If so, does there have to be Overo in the bloodline somewhere or is it just more common in the Overo? Or, is it just a genetic condition that any horse can actually carry?
I have only heard of it when breeding two Overos. |

The colt was bay, out of a black QH mare and a sorrel QH stud ?? that's where I was totally confused, I thought LW was a stricktly a paint horse issue? |

Well thats strange , it must be another condition , if the colt was bay likely not OLWS , BUT it has been noted that you can have two Qh's with the same gene alles that produce the syndrome , although not usually without the other signs such as all white or partially white foal 
Now thats very confusing for sure > Did you get a post mortum done on the foal ? what else was indicated if so ?

While atresi coli is commonly associated with OLWS it is sometimes seen in other situations.
Here are two links to research articles:
1: Discussing colic as a symptom;
2: In an Appaloosa and a Quarter Horse. |

Found a interesting article in the bovine industry that is linking early rectal palpation to this disease in the cattle. ??
In the lamas it seems that what is atresia coli is to have no colon, where the lw in horses is a incomplete large intestines ??? Dont' know if atresia coli is the same in horses as in lamas and cattle ?I would think that it would be the same. Just things that I was picking apart at different sites I was reading.
I have been very adimnet about the lw gene , it can be found in every breed. If it concerns someone then you should test all that you bred , not just the spotted paints.
Ev,On the lw issue, for example Painted Robin(regular registry paint horse, loud overo and not sabino) is 100 percent qh-foundation qh and he came from two solid color 100 percent foundation qhs. Many of your crop outs are frame overo coming from two solid qhs.
I had a frame overo stallion. I had a mare owner breed her solid bay mare to my fellow. She got a lw baby and the next got a solid bay colt. That was the one and only lw foal out of my stallion over 14 years. Its a gamble if you don't test , but in many eyes well worth the outcome of a nicely spotted overo if that is what you are breeding for. Chance, that is what life is about.
I also have some friends that are paint breeders/vets as well. They have noticed in their breeding program over the years that they get the biggest percent of lw babies out of bay solid mares bred to a overo stallion. Many different mares. They have been in the breeding bussiness for many years , way before much was known about the issue. Learning from what they did.
