Understanding host-microbiota interactions in the commercial piglet around weaning
(Nature Research, 2021-12-06)
Weaning is a critical period in the life of pigs with repercussions on their health and welfare and on the
economy of the swine industry. This study aimed to assess the efect of the commercial early ...
Indirect genetic effect model using feeding behaviour traits to define the degree of interaction between mates: an implementation in pigs growth rate
(Cambridge University Press, 2018-06-06)
An alternative implementation of the animal model including indirect genetic effect (IGE) is presented considering pair-mate-specific interaction degrees to improve the performance of the model. Data ...
Indirect genetic effects on the relationships between production and feeding behaviour traits in growing Duroc pigs
(Cambridge University Press, 2019-10-01)
Performance and feeding behaviour traits in growing pigs could be affected by social interaction effects when animals are raised in group. So, properly knowing the genetic correlations between direct ...
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 ...
Leveraging host-genetics and gut microbiota to determine immunocompetence in pigs
(BMC, 2021-10-24)
Background: The gut microbiota infuences host performance playing a relevant role in homeostasis and function of
the immune system. The aim of the present work was to identify microbial signatures ...
A gene co-association network regulating gut microbial communities in a Duroc pig population
(BMC, 2021-02-21)
Background. Analyses of gut microbiome composition in livestock species have shown its potential to contribute to the regulation of complex phenotypes. However, little is known about the host genetic ...
Expression analysis of candidate genes for fatty acid composition in adipose tissue and identifcation of regulatory regions
(Nature Research, 2018-02-01)
The aim of this work was to study the genetic basis of the backfat expression of lipid-related genes
associated with meat quality traits in pigs. We performed a genome-wide association study with ...
Expression-based GWAS identifies variants, gene interactions and key regulators affecting intramuscular fatty acid content and composition in porcine meat
(Nature Research, 2016-08-18)
The aim of this work is to better understand the genetic mechanisms determining two complex traits
affecting porcine meat quality: intramuscular fat (IMF) content and its fatty acid (FA) composition. ...
Transcriptional Characterization of Porcine Leptin and Leptin Receptor Genes
(Public Library of Science, 2013-06-18)
The leptin (LEP) and its receptor (LEPR) regulate food intake and energy balance through hypothalamic signaling. However, the LEP-LEPR axis seems to be more complex and its expression regulation has not ...
Indel detection from Whole Genome Sequencing data and association with lipid metabolism in pigs
(Public Library of Science, 2019-06-27)
The selection in commercial swine breeds for meat-production efficiency has been increasing among the past decades, reducing the intramuscular fat content, which has changed the sensorial and technological ...
