Population study of the Pura Raza Español Horse regarding its coat colour

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 c...

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.SciendoAgronomíaAGR273: Nuevas Tecnologías de Mejora Animal y de Sus Sistemas Productivos2018info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://hdl.handle.net/11441/102021https://doi.org/10.2478/aoas-2018-0016reponame:idUS.

description Coat colour has always been a valuable trait for horse breeders. However, preferences for this feature have changed over the years.
