Research

A pilot observational case study - Allergy against horses: Are curly horses an alternative for horse-allergic riders?

Below you find the pilot study of Dr. Wolfgang Mitlehner, Germany, ABCR member

 

 

 

 

Dr. Mitlehner currently continues this studies. The second study will test the hypothesis that regular contact to Curly Horses will induce a immuntolerance to horses.

Coefficent of Inbreeding (COI) of the Curly Horse

ABCR checked the average COI in the Closed Books. We used the reduced formular of Wright for it, based on 5 generations. Here are the results:

 

All ABCR closed book entries, regardless if still alive or not:

Full book: 1.72% (4,848 entries) / Blood book: 0.88% (765 entries / Closed book total: 1.61% (5,613 entries)

Current ABCR closed book breeding population (no geldings, not deceased, DOB > 1.1.1994):

Full book: 2.14% (2,182 entries) / Blood book: 1.12% (553 entries) / Closed book total: 1.95 % (2,735 entries)

For some indication, find the average inbreeding COI of other horse breeds below (Schäfer (2011)):

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It needs to be considered that the pedigrees, especially the ones of the older horses are often incomplete, and ABCR still works on correcting wrong parentage entries. However, since most of the work is done, these numbers can be considered as quite stable as per today. It will change with further registrations, though. More research on this topic will be done and published in the future.

 

We encourage all of our breeders to check the COI before breeding (we offer that as a free service to our members, non-members can buy that service, too), because a COI of below 1 % is recommended to avoid inbreeding depression within a population (DGfZ (1992)). For details contact [email protected]

Thanks to more than 5,600 registered horses and due to our high-functional database, we have all kind of Curly Horse information at a fingertip, which makes ABCR the first choice partner for research on the Curly Horse.

Wrong parentage

ABCR found due to a check of DNA samples, that about 90 horses have stated a wrong Sire or Dam in their pedigree. This could happen because horses have been registered BEFORE DNA samples were mandatory, and only LATER the samples of the Sire or Dam stated in these registrations have been handed in. The books have been corrected accordingly, and members can have a look in a full searchable pdf-studbook. If you are interested if your horses might be affected, please contact our Registrar, Melinda Martino, or Caren Schumann to get some information. Please also state why you are eligible to receive this information.
