Sire:
The term sire is used to refer to the father of a horse.
Dam:
The term dam is used to refer to the mother of a horse.
Stallion : We use the term
Stallion to refer to a living male horse, currently at stud.
Mare:
The term mare is used when referring to a female horse herself in situations such as the Stallion Finder or a Test
Mating, as opposed to when referring to her as the mother of another horse.
Linebreeding: The selection and
placement of ancestors within a pedigree with the aim of bringing forward the traits of those
ancestors.
Pedigree: The ancestral family,
to various generations, of a horse.
Generations:
A single generation is a set of parents. Direct sire and dam
are the first generation, grandparents the second and so on. Also known as a ‘remove’.
Duplicate: A duplicate in a
pedigree is an ancestor present through at least two different offspring.
Cross-duplicates: A duplicate that is
present in the sire’s half of the pedigree and the dam’s half, not just one or the other. Considered to be ‘true’
duplicates.
Sex-balanced: Duplicates that are
represented by both male and female offspring.
Family
Number: Bruce Lowe family numbers group families by their female taproot and
were numbered to indicated the most successful family (1) down through the lesser lights (47+) at the time of their
design many years ago. The family number still a very useful way to identify same named horses and their
background. Think of it as the horse’s surname.
LBI: Linebreeding Index. A
combination of four major linebreeding factors. Cross Duplicate Total, ¾ Duplications, Female Inbreeding and Sex
Balance. See the section in the LBI in theFAQ in this file.
CDT: The Cross Duplicate Total. This is a score based on the cross duplicates in a six
generation pedigree (7 as an option) that mates the selected mare with the stallion. The formula gives more points
for duplications in earlier generations. It is important to note, this is not a measurement of quality, just of the
amount of cross-duplicates in the pedigree. Although the quantity of cross-duplicates is not an indicator of
quality, the correct blend and variety of cross-duplicates is an essential factor in
linebreeding.
Three Quarter
Duplication: A duplication of a horse in the dams side of the pedigree and in the
sire’s dam’s section of the pedigree (the 2nd quarter).
FIB: Stands
for Female
Inbreeding. It is far more common to have male duplicates in a pedigree than female. However, many
pedigree analysts agree that duplicated females in the pedigree are advantageous. The FIB column shows the
number of different inbred females in the pedigree that mates the selected mare with the
stallion.
SB% (Sex
Balance): Reports another factor prized by many
pedigree analysts. Not only is it desirable to have ancestors cross-duplicated in the pedigree, linebreeding works
best when those ancestors are present though a son and a daughter. The SB% column shows the percentage of
duplications in the pedigree that are present through a son and daughter.
Wright’s Inbreeding
Coefficient. A method of calculating the amount
of inbreeding in a pedigree. Wright's Equation considers duplicated ancestors only if they are common to both sire
and dam.
Hardiman’s Coefficient
of Inbreeding. An alternate method calculating
and stating the degree of inbreeding in a pedigree. Hardiman's Method considers all inbred
ancestors.
Dosage.
A method of classifying racehorses on a scale from Sprinter
to Stayer, based on the performance of the offspring of Chefs de Race in a pedigree.
Modern Conduit
Mare: Modern Conduit Mares is a new book which outlines an innovative approach
toward evaluating thoroughbred pedigree, and applying aptitudinal characteristics passed through the female
family.
Reine-de-Course. The Reines-de-Course
("Queens of the Turf") series was created by Ellen Parker in 1991 as a guide to influential female Thoroughbred
families that could be utilized to improve the breed. Now, fifteen years after its inception, the number of
mares given the coveted designation of Reine-de-Course has grown to over 600. See http://www.reines-de-course.com
X-Factor: Term used to for the female X chromosome theory, relating to large hearts found in
outstanding racehorses.
