Con este trabajo, desarrollado por @rarribasglo y colaboradores, con la financiación de @AgEInvest, desde @MEGA_ULE, buscamos aportar resultados útiles a los ganaderos de @ASSAFESPAA y al sector #ovinolechero para afrontar sus retos actuales. #ResilSheep @FacVetLeon @unileon
Gracias a @SEOCSpain por el reconocimiento a la comunicación de @MEGA_ULE resultante del proyecto #ResilSheep en #congresoSEOC2026. Un sincero agradecimiento a los ganaderos colaboradores, esenciales para este trabajo, a @ASSAFESPAA, por su valiosa colaboración, y a @DeLaval.

En Cádiz, en el congreso de @SEOCSpain, presentando los resultados del proyecto #ResilSheep, financiado por @AgEInves, y realizado por el grupo @MEGA_ULE en colaboracion con @ASSAFESPAA. En la fase final del proyecto, acercando los resultados al sector #ovinolechero @FacVetLeon
Also at @wcgalp2026, @rarribasglo presented the results of a #GWAS on #resilience indicators in #dairysheep derived from the #ResilSheep project funded by @AgEInves. The candidate #genes identified may help to unravel the #biologicalmechanisms underlying this complex phenotype.
At @WCGALP2026 @Beatriz_GG_Leon presented results from the #ResilSheep project, funded by @AgEInves. For 3 indicators of general #resilience in #dairysheep, we showed how the lactation curve fitting method chosen influences the estimation of genetic parameters #EMOTIONSpackage
Also, @AroaSuarez presented interesting results of single-cell deconvolution analyses, carried out within the @EUPAHW European Partnership, revealing mammary cell and gene dynamics in ewes following an intramammary inflammatory challenge. 🐑🧬 #WCGALP26 #AnimalHealth #SingleCell
At #WCGALP26, @MarkoVrcan presented our LIVER #transcriptomic study on the intergenerational effects of maternal protein restriction in replacement ewe lambs. #OxidativeStress & #EndoplasmicReticulum pathways emerged as key biological processes affected in the liver. @FacVetLeon
The MEGA-ULE group at #WCGALP2026 in Madison, Wisconsin! 🇪🇸
Proud to present the latest research of our group focused on #dairysheep production, from #genomics and #transcriptomics to prediction of #resilience indicators.
Learning from cutting-edge research around the world.
El 21/01/2026 @Maria21Alonso de @MEGA_ULE defendió su tesis doctoral (compendio de publicaciones) centrada en el Uso de datos transcriptómicos para el estudio de la deposición grasa en #corderoslechales. Enhorabuena de todo el grupo a la nueva doctora! #RNAseq #ovino @FacVetLeon
Contentos de ver la interacción entre estudiantes y #asociaciones de ganaderos a través de los trabajos de la asignatura de Cría y Mejora Animal de @FacVetLeon. Un ejemplo, desde la Asociación de ganaderos de bovino de raza #Pajuna.

Recopilación de los hilos sobre trabajos realizados por varios alumnos del #MásterInvBiotecyBiom de @unileon sobre estudios #GWAS relacionados con un tema de su interés. Genial ver, a través de su curiosidad, el gran abanico de fenotipos al que se aplica esta metodología.
And we’d also like to highlight the achievement of
@Pablo_bio2 's project, which won the 1st Prize at the AI Hackathon for Livestock Data 2024, organized by
@v_hive29966 at @UniOfSurrey! 🎉🏆vhive.buzz/ai-hackathon
Enhorabuena a @Maria21Alonso, estudiante de doctorado de @MEGA_ULE, por el Premio a la Mejor Comunicación Oral de las I Jornadas de Jóvenes Investigadores en @unileon. Gracias a @AIF_unileon por la organización. #jovenesinvestigadores

Finalizadas las I Jornadas de Jóvenes Investigadores en la FCC Biológicas y Ambientales de @unileon. Esperamos poder repetirlas el próximo año.

Also, within the framework of the @SmarterprojectE and the #EPIMILKSHEEP(@AgEInves) project, we have had the opportunity to learn about the dynamic transcriptomic changes in the sheep's lactating mammary gland after an E. coli LPS inoculation bit.ly/4h0Pd3r @FacVetLeon
One of our studies within the @SmarterprojectE, in collaboration with @Igm_Leon, has shown how the information from the milk transcriptome can be used to identify biomarkers enhance feed efficiency and reduce nutritional costs in dairy ewes bit.ly/3W0hsra @FacVetLeon
#EAAP2024: @MarkoVrcan of @MEGA_ULE has presented a study, performed within the framework of the national #REGEMAV project (@AgEInves), analyzing genomic regions associated to resistance against Maedi Visna infections in two Spanish sheep breeds @EAAPofficial @FacVetLeon @unileon
Also @Maria21Alonso has presented results related to #EpiMilkSheep & #ResilSheep national projects (@AgEInves) about how a protein restriction in ewe lambs may affect their resilience against later inflammatory challenges of the mammary gland @EAAPofficial @FacVetLeon @ASSAFESPAA
Yesterday I had the opportunity to tell a little bit more about the effect of protein restriction during growth on the #immune response by analysing the #transcriptome of 🐑🧬

In #EEAP2024, our students @Maria21Alonso
and @MarkoVrcan are presenting results related to the ongoing #QUALITYLAMB (@educacyl) project, where relevant biological mechanisms for suckling lamb production have been identified. @RazaChurra @ASSAFESPAA @FacVetLeon @EAAPofficial

Using fat #transcriptome data from two local sheep breeds, we have further investigated how #lncRNAs are involved in the regulation of #fat deposition, providing insights that can be used to improve carcass quality traits in 🐑 @MEGA_ULE 🧬

In this paper of our group, published in @jdairyscience in collaboration with researchers of @Igm_Leon, milk metabolites are assessed as biomarkers for predicting feed efficiency in dairy sheep. @SmarterprojectE @unileon @FacVetLeon
