Why should we repeat the breeding?
Once you have constructed what you believe is the best possible genetic combination for your sport horse foal, the experts advise that you repeat the breeding, at least once.
Even Tesio did this, and the science of genetics backs this advice up.

The FEI has cancelled international events in 10 countries on the European mainland with immediate effect and until 28 March 2021 due to the rapid evolution of a very aggressive strain of the neurological form of Equine Herpes Virus (EHV-1), which originated in Valencia (ESP) and has already... + continue reading
France is setting an example. This comes after the behavior of certain of its riders who did everything they could to ride in competition this weekend despite participating in Valencia in recent weeks. Equestrian competitions and gatherings have now been suspended in France!

Degrees of heritability and genetic correlations in the Hanoverian breed.
"How safe is it to assume that the shape of a horse's head will be passed on from one generation to the next?
What happens to the basic gaits and the typiness if we select for jumping ability only?
Ludwig Christmann researched these kinds of statements in the course of his study of the development of the breed value estimation based on the results from mare inspections and mare performance tests at the Institute of Animal Breeding at the University in Goettingen. These results are not only necessary for the estimation of the breed values, they, in themselves, also bear important information with respect to breeding."
The scores of mare inspections and mare performance tests of a total of 5,347 mares tested from 1987 to 1993 were taken in to consideration for this project.
The degree of heritability is a way to measure the genetic strength of a characteristic, up to... More
Once you have constructed what you believe is the best possible genetic combination for your sport horse foal, the experts advise that you repeat the breeding, at least once.
Even Tesio did this, and the science of genetics backs this advice up.
Bowling said, "The random assortment of chromosome pairs during gamete formation means we can not predict the exact proportion of genes that any two siblings have in common."
Each of the genes can divide and combine in many variations and your first, or even second mating may not get the most beneficial shuffle of the genetic deck.
If you are planning your matings correctly, even the lesser of the foals should be a very good horse, but the variation possible doesn't insure that the first foal will be the best of the bunch, so repeat the breeding, at least once.
If you doubt the variation possible you only have to look at your... More
We often think of pregnancy as a delicate and fragile condition. When it comes to horses, this perception is perhaps due to the mare's relatively poor reproductive performance in comparison to other domestic animals.
However, in a natural setting, the mare does comparatively well reproductively. Therefore, this seemingly poor performance is due as much to improper management as to any reproductive deficiency. Fortunately, management is something we can control.
As a conscientious owner, you probably have many questions about caring for your expectant mare. In truth, you may be a little worried. Relax. With a little TLC, your mare should progress through her pregnancy without mishap. Proper nutrition, deworming, exercise, and vaccinations will help ensure a healthy pregnancy, and you can look forward to the birth of your foal with greater confidence.

WFFS was initially identified in warmblood breeds, but recent research at the VGL identified a low allele and carrier frequency of the WFFS variant in Thoroughbreds as well (2.4% carrier frequency in the 716 horses evaluated).
The study, an international collaboration led by UC Davis Veterinary Genetics Laboratory Director Rebecca Bellone, PhD, screened more than 4,000 horses from 38 horse breeds in the United States and Europe.
200 horses (4.9%) representing 21 breeds carried the WFFS allele. Most of these breeds were warmbloods; however, a few non-warmblood breeds also carried the allele. The non-warmblood exceptions include the Thoroughbred (carried by 17 out of 716 horses), the Knabstrupper (3/46), the Haflinger (2/48), and the American Sport Pony (1/12).
The WFFS allele was detected in 17 out of the 19 tested warmblood breeds, with the highest carrier frequency observed in Hanoverians and Danish Warmbloods (both approximately 17.3%). The allele was not... More
"I’m a pedigree and database nerd, so a resource like this is practically like oxygen to me.
This is a wonderful, wonderful resource. I use it a LOT! I can also appreciate the challenges that go with maintaining such a vast database. You all do a fantastic job!"
"Best horse search site EVER!!! The pedigrees are so complete for generations and offspring lists. And I can't express how much I appreciate the pictures. I've been doing a project on TBs with color and to be able to find pics of offspring and generations back was beyond helpful. Thank you!!!!"
"I am Sporthorse breeder in South Africa, and have been using your website for a while now. I absolutely love the versatility of it. Very user friendly."
"I really appreciate this website, and the data base, and it's my preferred online pedigree tool for breeding purposes! Love it, and use it daily, multiple times per day. In particular the test mating function is invaluable!"
