The genetic evaluation o f sport horses is com m on practice on the Continent and in
Ireland but, until now, has not been carried out in Great Britain. The aim o f this
project was to derive m odels for predicting breeding values for British bred sport
horses and hence develop procedures for their evaluation. The research consisted
predom inantly o f the estim ation o f genetic and phenotypic param eters from two
datasets; results from the Young Horse Evaluation Series (YHE), which assesses 4
year old potential sport horses, and com petition data on UK eventing horses. Eleven
traits were m easured in the YHE, including a veterinary score, conform ation, paces
and jum ping ability. A small dataset led to some problem s and m eant that
heritabilities could not be predicted, however, the predicted repeatabilities were
sufficient in m agnitude and precision to indicate that the YHE m ay prove useful as a
test o f individuals. A m uch larger and more com prehensive dataset was available for
UK eventing horses. Penalty points from each o f the three phases - dressage,
show jum ping and cross country - and overall com petition were converted to normal
scores for analysis. Each phase was separated into 4 different grades o f com petition
- pre novice, novice, interm ediate and advanced. Results showed heritabilities
significantly different from zero for all phases (0.02-0.23). Correlations between the
grades for each phase were high, suggesting that it should be possible to predict a
horse’s perform ance at advanced level by its perform ance at novice or pre novice
level. For the first tim e, the proportions o f variance attributed to the rider, perm anent
environm ental effect and genetics o f the horse were estim ated separately. These
estim ates showed that for m ost grades and phases the m ost important com ponent was
the perm anent environm ental effect, w ith the rider and genetics becom ing more
im portant as the grades become more challenging. This analysis allowed the
successful prediction o f estim ated breeding values (EBVs), horse values (HVs) and
rider values (RVs). Using these values, the intensity o f selection on sires, horses and
riders progressing from the pre novice to advanced grades in each o f the phases of
eventing com petition was investigated.
