Impact of multi-output and stacking methods on feed efficiency prediction from genotype using machine learning algorithms
(Wiley, 2023-07-05)
Feeding represents the largest economic cost in meat production; therefore, selection to improve traits related to feed efficiency is a goal in most livestock breeding programs. Residual feed intake ...
A systems biology framework integrating GWAS and RNA-seq to shed light on the molecular basis of sperm quality in swine
(BMC, 2020-12-08)
Background
Genetic pressure in animal breeding is sparking the interest of breeders for selecting elite boars with higher sperm quality to optimize ejaculate doses and fertility rates. However, the ...
Variability-specific differential gene expression across reproductive stages in sows
(Elsevier, 2013-10-11)
Differential gene expression analyses typically focus on departures across mathematical expectations (i.e. mean) from two or more groups of microarrays, without considering alternative patterns of ...
Genetic diversity and selection signatures of the beef ‘Charolais de Cuba’ breed
(Nature Research, 2018-07-20)
In this study, we used BovineSNP50 Genotyping BeadChip data to estimate the structure, putative
ancestral origin as well as to identify regions with selective sweeps that may have had an important
role ...
Opportunities and limits of combining microbiome and genome data for complex trait prediction
(BMC, 2021-08-06)
Background
Analysis and prediction of complex traits using microbiome data combined with host genomic information is a topic of utmost interest. However, numerous questions remain to be answered: how ...
Identification of rumen microbial biomarkers linked to methane emission in Holstein dairy cows
(Wiley, 2019-08-16)
Mitigation of greenhouse gas emissions is relevant for reducing the environmental impact of ruminant production. In this study, the rumen microbiome from Holstein cows was characterized through a ...
Analysis of porcine adipose tissue transcriptome reveals differences in de novo fatty acid synthesis in pigs with divergent muscle fatty acid composition
(BMC, 2013-12-01)
Background: In pigs, adipose tissue is one of the principal organs involved in the regulation of lipid metabolism.
It is particularly involved in the overall fatty acid synthesis with consequences in ...
Use of Bayes factors to evaluate the effects of host genetics, litter and cage on the rabbit cecal microbiota
(BMC, 2022-06-27)
Background
The rabbit cecum hosts and interacts with a complex microbial ecosystem that contributes to the variation of traits of economic interest. Although the influence of host genetics on microbial ...
Selection for environmental variance of litter size in rabbits
(BMC, 2017-05-22)
Background
In recent years, there has been an increasing interest in the genetic determination of environmental variance. In the case of litter size, environmental variance can be related to the capacity ...
Analysis of the causal structure of traits involved in sow lactation feed efficiency
(BMC, 2022-07-26)
Background
Feed efficiency during lactation involves a set of phenotypic traits that form a complex system, with some traits exerting causal effects on the others. Information regarding such ...
