The bloodline of a race horse equates to a family tree. It represents a horse’s descendants on the male and female parent’s side, and is measure of a horse’s
pedigree. A horse’s mother and father are known as the
dam
and
stallion, who are coupled to produce a
foal.
When a horse is offered at the sales the bloodline is an important factor in determining the price. Horses are bred to produce qualities in combination from the male and female bloodline. Horses bred for racing are called
thoroughbreds
and they are known for their speed and racing ability.

How is Bloodline used in Sports Betting?
The objective of breeding a race horse is to produce an animal that will be effective on the race track. The ultimate goal for breeders who produce
flat racing
horses is to breed a horse that can win Classics and in particular the
Epsom Derby.
The bloodline of a horse should determine its physical attributes but this is not an exact science. There have been many examples of an excellently bred horse not being able to run fast or have the aptitude for beating other horses. Conversely horses with a modest bloodline can overachieve and produce great results on the track.
In juvenile races, in which the horses have little or no experience, the
horse racing odds
will partly be based on breeding and the bloodline. Flat and
jump racing
horses have different bloodlines and a flat stallion will not pass on the attributes that make for a good jumps horse and vice versa.
The records of bloodlines and results on the track will determine the quality of the breeding stock and offspring produced for racing. These factors go back generations and horses often show the qualities of relatives from many years ago. However, pedigree is not always an accurate guide to quality but that is the nature of breeding thoroughbreds.
