A genome-wide association study of mare fertility in the Pura Raza Español horse
Laseca, Nora; Demyda-Peyrás, S.; Valera Córdoba, M.; Ramón, M.; Escribano, Begoña M.; Perdomo-González, Davinia I.; Molina, Antonio (Elsevier, 2022)Despite the economic importance of fertility for the horse industry, few efforts have been made to achieve a better understanding of the genetic mechanisms underlying its control. This is probably due to the difficulty of ... -
Allele/haplotype variation in the MHC-DQA2 gene in Spanish sheep and its association with footrot susceptibility
Anaya, Gabriel; Negro, S.; Zhou, H.; Hickford, J.; Molina, Antonio (Elsevier, 2021)Footrot is a contagious disease that affects the hoof of sheep and other ungulates.

Un estudio sobre el rendimiento de separación de tubos helicoidales aplicados a flujos bifásicos de agua y aceite de oliva
Vallesquino-Laguna, Pedro; Molina, Antonio (Universitat Politècnica de València, 2019)Studies on water and oil two–phase flows, developed in helical pipe separators, are not numerous and seem to be currently restricted to the petrochemical industry. The present work has been done to study the performance ... -
Fine-tuning genomic and pedigree inbreeding rates in equine population with a deep and reliable stud book: the case of the Pura Raza Española horse
Perdomo-González, Davinia I.; Laseca, Nora; Demyda-Peyrás, S.; Valera, Mercedes; Cervantes, I.; Molina, Antonio (Springer, 2022)Estimating inbreeding, which is omnipresent and inevitable in livestock populations, is a primary goal for management and animal breeding especially for those interested in mitigating the negative consequences of inbreeding. ... -
Genomic Population Structure of the Main Historical Genetic Lines of Spanish Merino Sheep
Granero, A.; Anaya, Gabriel; Demyda-Peyrás, S.; Alcalde Aldea, M.J.; Arrebola, F.; Molina, Antonio (MDPI, 2022)According to historiographical documentation, the Romans first began to select Merino sheep in the Iberian Peninsula during the first century, with the aim of obtaining a breed appreciated for the quality of its wool. This ... -
Genomic screening of allelic and genotypic transmission ratio distortion in horse
Laseca, Nora; Cánovas, Ángela; Valera, Mercedes; Id-Lahoucine, Samir; Perdomo-González, Davinia I.; Fonseca, Pablo A. S.; Demyda-Peyrás, S.; Molina, Antonio (Public Library os Science, 2023)The phenomenon in which the expected Mendelian inheritance is altered is known as transmission ratio distortion (TRD). The TRD analysis relies on the study of the transmission of one of the two alleles from a heterozygous ... -

Prevalence of Sex-Related Chromosomal Abnormalities in a Large Cohort of Spanish Purebred Horses
Demyda-Peyrás, S.; Laseca, Nora; Anaya, Gabriel; Kij-Mitka, Barbara; Molina, Antonio; Karlau, Ayelén; Valera Córdoba, M. (MDPI, 2023)Chromosomal abnormalities are largely associated with fertility impairments in the domestic horse. To date, over 600 cases of individuals carrying abnormal chromosome complements have been reported, making the domestic ... -
Relationship between somatic cell score and fat plus protein yield in the first three lactations in Spanish florida goats
JIménez-Granado, Rocío; Molina, Antonio; Sánchez-Rodríguez, M.; Ziadi, Chiraz; Menéndez-Buxadera, A. (MDPI, 2024)The aim of this study was to estimate genetic parameters of somatic cell score (SCS) and fat plus protein yield (FPY) using repeatability (RM) and random regression (RRM) models in Florida goats. The data consisted of ... -
Reproductive traits in Pura Raza Española mares manifest inbreeding depression from low levels of homozygosity
Laseca, Nora; Ziadi, Chiraz; Perdomo-González, Davinia I.; Valera, Mercedes; Demyda-Peyrás, S.; Molina, Antonio (Wiley, 2023)Inbreeding depression is a genetic phenomenon associated with the loss of fitness and mean phenotypic performance due to mating between relatives.
