dc.description.abstract | Coat colour has always been a valuable trait for horse breeders. However, preferences for this
feature have changed over the years. In this research, the Pura Raza Español horse (PRE) population
was divided into four subpopulations (Grey, Bay, Black and Others), according to the most
frequent coat colours and those of their ancestors. The purpose was to analyse genetic variability,
reproductive parameters and distances among subpopulations during three key periods in the history
of the breed: before 1960, from 1960 to 2000 and after 2000. The subpopulations composed of
animals with ancestors with the same coat colour showed higher values of recent inbreeding (ranging
from 7.13% to 10.44%) and a greater Nei’s minimum distance between them, as a result of
more inbred matings than those carried out in families with members with different coat colours.
Non-pure subpopulations also showed more similar recent inbreeding values (between 6.63% and
6.74%). Strikingly, the productive life of Pure bay, Pure black and other subpopulations with
minority coat colours was considerably longer (10.79, 10.08 and 9.11 years, respectively) compared
to the values of grey PRE horses (6.01 and 7.98 years), which is the subpopulation with the
highest census. These results, together with shorter generation intervals of black stallion-offspring
(5.51 years via father-son and 6.39 years via father-daughter) and the fact that this coat colour was
not present in the breed until two decades ago, highlight the recent trend towards the breeding of
black animals. | es |
