Determining Foundation Blood Contribution:

When determining how much Foundation blood an IPAA qualifying horse has, we first take a look at the pedigree. A horse is made up of numerous generations of breeding.  Each generation contributing a certain percentage of it’s blood.  For examples sake we take a stallion and a mare.  Each of these two horses if bred to one another contributes 50% of itself in any resulting foal, just as their sire and dam contributed 50% of themselves and so on and so fourth.  Each generation has a contribution to make and each generation contributes half of the previous generation.

In the instance of an IPAA qualifying horse we must look at the registration number of the ancestors of that horse.  Because IPAA counts only the first 139,999 horses with a Foundation (F prefix) or Permanent (# prefix) number and only those registered prior to 1971 to total up the 75% Foundation blood requirement we need to make note of what generation such a registration might fall in.  If a registration number of #166 falls in the sire’s generation of the subject horse we know that the sire has contributed 50% Foundation blood.  (Note that when each generations contribution has been determined there is no further need to continue calculating back through those lines.)  Now we focus on the dam’s side.  If the subject horses maternal grand dam has a registration number F2306 we know that she has contributed 25% Foundation blood, so the subject horse has just qualified for IPAA registration with 75% Foundation breeding and or blood.  This process can go and on until an entire pedigree is researched in order to determine a Foundation blood percentage.

Appaloosa Horse Club registered horses bearing a “T” prefix before a registration number lower than 139,999 and registered before 1971 shall be treated on an individual basis for purposes of figuring their Foundation blood contribution.  Such “T” registered horse(s) whose ancestry traces to unregistered sire and dam or unknown sire and dam shall be allotted 50% of whatever generational total it would have earned if it’s ancestor(s) had been documented/recorded and traceable to a Foundation or Permanent registered horse.
