Challenging selection for consistency in the rank of endurance competitions
(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 ... -
Does the Acknowledgement of S1-Casein Genotype A ect the Estimation of Genetic Parameters and Prediction of Breeding Values for Milk Yield and Composition Quality-Related Traits in Murciano-Granadina?
(MDPI, 2019)A total of 2090 lactation records for 710 Murciano-Granadina goats were collected during the years 2005–2016 and analyzed to investigate the influence of the αS1-CN genotype on milk yield and components (protein, fat, and ... -
Does the Acknowledgement of αS1-Casein Genotype Affect the Estimation of Genetic Parameters and Prediction of Breeding Values for Milk Yield and Composition Quality-Related Traits in Murciano-Granadina?
(MDPI, 2019)A total of 2090 lactation records for 710 Murciano-Granadina goats were collected during the years 2005–2016 and analyzed to investigate the influence of the αS1-CN genotype on milk yield and components (protein, fat, and ... -

Estimation of Genetic Parameters for Litter Size and Growth Traits in a Prolific Line of Tunisian Barbarine Sheep
(MDPI, 2024)This study aimed to assess genetic parameters for ewe productivity in a Tunisian Barbarine sheep line. The traits studied were litter size (LS), birth weight (BW), weight at 90 days (W90), and average daily gain between ... -
Genetic inbreeding depression load for fertility traits in Pura Raza Española mares
(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
(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 Parameters of Somatic Cell Score in Florida Goats Using Single and Multiple Traits Models
(MDPI, 2022)A total of 1,031,143 records of daily dairy control test of Spanish Florida goats were used for this study. The database was edited, and only the records of the first three lactations were kept. The final database contained ... -
Prediction of adult conformation traits from shape characteristics of Pura Raza Español foals
(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 ... -
Relationship between somatic cell score and fat plus protein yield in the first three lactations in Spanish florida goats
(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 ... -
Selection Criteria for Improving Fertility in Spanish Goat Breeds: Estimation of Genetic Parameters and Designing Selection Indices for Optimal Genetic Responses
(MDPI, 2021)The aim of this study was to estimate genetic parameters for several female fertility criteria and to choose the most suitable selection index in Spanish Florida and Payoya goat breeds. In this study, we analyzed as fertility ... -
Structural organization of genetic diversity and ethofunctional characterization in the Andalusian donkey breed
(Universidad de Córdoba, UCOPress, 2019)Tools allowing to understand the evolution of donkey populations in time, the future trends that these populations describe, and the factors conditioning such trends, become invaluably critical when aiming at preserving ... -
Survival analysis of productive life in Florida dairy goats using a Cox proportional hazards model
(Wiley, 2023)Longevity is an economically important trait, since extending the functional life of a doe would allow us to keep the most productive females in the herd as long as possible, and this could result in the increased profitability ...
