A genomewide association study in divergently selected lines in rabbits reveals novel genomic regions associated with litter size traits

Sosa-Madrid, Bolivar Samuel; Santacreu Jerez, María Antonia; Blasco Mateu, Agustín; Fontanesi, Luca; Pena, R.; Ibáñez-Escriche, Noelia (Blackwell Publishing, 2020-03)

[EN] Uterine capacity (UC), defined as the total number of kits from unilaterally ovariectomized does at birth, has a high genetic correlation with litter size. The aim of our research was to identify genomic regions ...
Divergent selection for fat index in Pannon Ka rabbits: genetic parameters, selection response

Kasza, R.; Matics, ZS.; Gerencsér, ZS.; Donkó, T.; Radnai, I.; Szendrő, ZS.; Nagy, I. (Universitat Politècnica de València, 2020-09-30)

[EN] The objective of this study was to estimate the response to selection for total body fat content of rabbits measured by computer tomography (CT). A divergent selection experiment was performed using Pannon Ka rabbits, ...
Effect of divergent selection for uterine capacity on embryonic survival and development at 30 h post-mating in unilaterally ovariectomized rabbit females

Peiró Barber, Rosa Mª; Gallego, M.; Blasco Mateu, Agustín; Santacreu Jerez, María Antonia (Editorial Universitat Politècnica de València, 2015-12-23)

[EN] Uterine capacity has been proposed as an indirect way to increase litter size. The aim of this work is to study the effect of a divergent selection for uterine capacity (UC) on reproductive traits at 30 h post mating ...
Effect of Embryonic and Maternal Genotype on Embryo and Foetal Survival in Rabbit

Vicente Antón, José Salvador; Llobat, L.; Jiménez Trigos, María Estrella; Lavara García, Raquel; Marco Jiménez, Francisco (Wiley, 2013-06)

[EN] The aim of this work was to study the influence of embryonic and maternal genotype of two lines of rabbits selected by growth rate (line R) and litter size at weaning (line A) on prenatal survival. Embryos were recovered ...
Genetic and non-genetic factors affecting rabbit doe sexual receptivity as estimated from one generation of divergent selection

Theau.Clément, M.; Sécula, A.; Saleil, G.; Monniaux, D.; Brecchia, G.; Boiti, C.; Bodin, L.; Brun, J.M. (Editorial Universitat Politècnica de València, 2015-09-30)

[EN] Sexual receptivity of rabbit does at insemination greatly influences fertility and is generally induced by hormones or techniques known as “biostimulation”. Searching for more sustainable farming systems, an original ...
Genome-wide association study for intramuscular fatty acid composition in divergently selected rabbit lines

Laghouaouta, Houda (Universitat Politècnica de València, 2020-07-30)

[EN] Intramuscular fat (IMF) content and composition are key traits determining meat quality. A divergent selection experiment for IMF content in Longissimus thoracis et lumborum muscle was carried out during nine generations ...
Genome-Wide Association Study of Maternal Genetic Effects on Intramuscular Fat and Fatty Acid Composition in Rabbits

El Nagar, Ayman G.; Heddi, Imen; Sosa-Madrid, Bolivar Samuel; Blasco Mateu, Agustín; Hernández, Pilar; Ibáñez-Escriche, Noelia (MDPI AG, 2023-10)

[EN] Maternal genetic effects (MGE) could affect meat quality traits such as intramuscular fat (IMF) and its fatty acid composition. However, it has been scarcely studied, especially in rabbits. The objectives of the present ...
Genomic analysis of divergently selected experimental lines in rabbit

Sosa Madrid, Bolívar Samuel (Universitat Politècnica de València, 2020-04-23)

[ES] La selección divergente puede cambiar las frecuencias de los marcadores genéticos en direcciones opuestas, produciéndose frecuencias alélicas intermedias en estos marcadores cuando ambas líneas divergentes son ...
Genomic regions influencing intramuscular fat in divergently selected rabbit lines

Sosa-Madrid, Bolivar Samuel; Hernández, Pilar; Blasco Mateu, Agustín; Haley, Chris S.; Fontanesi, Luca; Santacreu Jerez, María Antonia; Pena, Romi N.; Navarro, Pau; Ibáñez-Escriche, Noelia (Blackwell Publishing, 2020-02)

[EN] Intramuscular fat (IMF) is one of the main meat quality traits for breeding programs in livestock species. The main objective of this study was to identify genomic regions associated with IMF content comparing two ...
Intramuscular Fat Selection in Rabbits Modifies the Fatty Acid Composition of Muscle and Liver Tissues

Zubiri-Gaitán, Agostina; Blasco Mateu, Agustín; Ccalta, Ruth; Satué, Katy; Hernández, Pilar (MDPI AG, 2022-04)

[EN] Simple Summary Intramuscular fat content improves the juiciness, tenderness, and flavor of meat, but it can also affect its nutritional quality. A divergent selection experiment for intramuscular fat content was ...
