Challenging selection for consistency in the rank of endurance competitions
Cervantes, I.; Bodin, L.; Valera, M.; Molina Alcalá, Antonio; Gutierrez, J.P. (BioMed Central (Springer), 2020)Control of the environmental variability by genetic selection offers possibilities for new selection objectives for productive traits. This methodology aims at reducing heterogeneity in productive traits and has been applied ... -
Designing an early selection morphological traits index for reproductive efficiency in Pura Raza Española mares
Perdomo-González, D.I.; Sánchez-Guerrero, M.J.; Bartolomé, E.; Guedes dos Santos, Rute; Molina Alcalá, Antonio; Valera, M. (Oxford Academic, 2024)The low rate of reproductive efficiency in horses may be linked to the equine industry’s practice of maintaining breeding stock that stands out for its athletic or morphological performance but exhibits poor reproductive ... -
Genetic inbreeding depression load for fertility traits in Pura Raza Española mares
Perdomo-González, D.I.; Molina, A.; Sánchez-Guerrero, M.J.; Bartolomé, E.; Varona, L.; Valera, M. (Oxford Academic, 2021)Fertility is a key factor in the economic success of horse farms. However, it has received little attention due to the difficulty of measuring fertility objectively. Since its studbook creation (1912), the Pura Raza Española ... -
Genetic inbreeding depression load for morphological traits and defects in the Pura Raza Española horse
Poyato-Bonilla, J.; Perdomo-González, Davinia I.; Sánchez Guerrero, María José; Varona, L.; Molina Alcalá, Antonio; Casellas, J.; Valera, M. (BioMed Central (Springer), 2020)Background Inbreeding is caused by mating between related individuals and is associated with reduced fitness and performance (inbreeding depression). Several studies have detected heterogeneity in inbreeding depression ... -
Genetic Structure Analysis of the Pura Raza Español Horse Population through Partial Inbreeding Coefficient Estimation
Perdomo-González, Davinia I.; Sánchez Guerrero, María José; Molina Alcalá, Antonio; Valera, M. (MDPI, 2020)The aim of this work was to analyze genetic parameters such as the inbreeding coefficient (F), relatedness coefficient (AR) and partial inbreeding coefficient (Fij) of the whole PRE population, and the ancestors which ... -
Prediction of adult conformation traits from shape characteristics of Pura Raza Español foals
Gómez-Ortiz, M.D.; Molina, A.; Sánchez-Guerrero, M.J.; Valera, M. (Elsevier, 2021)Horse conformation has been proposed as an indirect indicator of performance, since their genetic correlations are often positive and high. In Pura Raza Español (PRE) horses, the selection of conformation traits more related ... -
Quantitative analysis of parent-of-origin effect in reproductive and morphological selection criteria in the Pura Raza Española horse
Perdomo-González, D.I.; Varona, L.; Molina Alcalá, Antonio; Laseca, Nora; Valera, M. (Wiley, 2023)It is generally assumed that parents make a genetically equal contribution to their offspring, but this assumption might not always hold. This is because the expression of a gene can be blocked by methylation during ...
