Invited review: Novel methods and perspectives for modulating the rumen microbiome through selective breeding as a means to improve complex traits: Implications for methane emissions in cattle
(2023-02-03)
The rumen microbiome is responsible for methane emission in ruminants. The study of microbes in the rumen has attracted great interest in the last decade. High-throughput sequencing technologies have been key in expanding ...
Study of the host genetic control over the ruminal microbiota and their relationships with methane emissions in dairy cattle
Estudio del control genético del hospedador sobre la microbiota ruminal y sus relaciones con emisiones de metano en bovino lechero
(2021-07-01)
The analysis of the host genetic control over its microbiota has recently been pointed out as a promising theme in different fields of study. The relationship between the host-microbiome holobiont and phenotypes in dairy ...
Efecto del polimorfismo DGAT1 K232A sobre fenotipos productivos y reproductivos en el ganado bovino
Effect of DGAT1 K232A polymorphism on productive and reproductive fenotypes in cattle
(2018-06-18)
El polimorfismo genético DGAT1 K232A es una sustitución no conservadora en el gen del mismo nombre, se trata de un cambio del aminoácido alanina por lisina, que tiene como consecuenciamayor actividad de la enzimaDiacilglicerol ...
Structural equation models to disentangle the biological relationship between microbiota and complex traits: Methane production in dairy cattle as a case of study
(2019-09-18)
The advent of metagenomics in animal breeding poses the challenge of statistically modelling the relationship between the microbiome, the host genetics and relevant complex traits. A set of structural equation models (SEMs) ...
Impact of oestrus synchronization devices on ewes vaginal microbiota and artificial insemination outcome
(2023-03-23)
Introduction: The low pregnancy rate by artificial insemination in sheep represents a fundamental challenge for breeding programs. In this species, oestrus synchronization is carried out by manipulating hormonal regimens ...
