A dimensional reduction approach to modulate the core ruminal microbiome associated with methane emissions via selective breeding
(2021-03-15)The rumen is a complex microbial system of substantial importance in terms of greenhouse gas emissions and feed efficiency. This study proposes combining metagenomic and host genomic data for selective breeding of the ... -
Additive genetic and heterosis effects for milk fever in a population of Jersey, Holstein × Jersey, and Holstein cattle under grazing conditions
(2018-08-30)The aim of this study was to estimate additive genetic and heterosis effects for milk fever (MF) in Costa Rican dairy cattle. A farm-based management information software was used to collect 223,783 parity records between ... -
Holobiont effect accounts for more methane emission variance than the additive and microbiome effects on dairy cattle
(2021-05-11)Rumen microbiota has been previously related to phenotypic complex traits of relevance in dairy cattle. The joint analysis of the host’s genetic background and its microbiota can be statistically modelled using similarity ... -
Improving phenotypic prediction in dairy cattle breeding using the metagenome
(2019-11-18)Ruminants evolved from Artiodactyla in the Eocene 50–70 million years ago. In that period, grass began to populate the largest land surface on Earth. Since then, ruminants and their microbiota have evolved together in ... -
Predicting complex traits using microbiome information: A comparison of metagenome distance matrices
(2018)The aim of this study was to compare ordination methods for microbiota distance matrices, in order to estimate variance components for complex traits prediction including the microbiome in its estimation. Seven ordination ... -
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) ... -
Study of the host genetic control over the ruminal microbiota and their relationships with methane emissions in dairy cattle
(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 ... -
Variance components estimation of complex traits including microbiota information
(2018-07-13)The influence of the microbiome on relevant complex traits for dairy cattle, such as feed efficiency or methane emissions has been well established. Further, recent studies have released evidences on the control of the ...
