A meta-analysis of genetic and phenotypic diversity of European local pig breeds reveals genomic regions associated with breed differentiation for production traits
(BMC, 2023-12-07)
Background
Intense selection of modern pig breeds has resulted in genetic improvement of production traits while the performance of local pig breeds has remained lower. As local pig breeds have been ...
Polymorphisms of the cryptochrome 2 and mitoguardin 2 genes are associated with the variation of lipid-related traits in Duroc pigs
(Nature Research, 2019-06-21)
The genetic factors determining the phenotypic variation of porcine fatness phenotypes are still largely
unknown. We investigated whether the polymorphism of eight genes (MIGA2, CRY2, NPAS2, CIART,
ARNTL2, ...
Comparing the mRNA expression profile and the genetic determinism of intramuscular fat traits in the porcine gluteus medius and longissimus dorsi muscles
(BMC, 2019-03-04)
Background
Intramuscular fat (IMF) content and composition have a strong impact on the nutritional and organoleptic properties of porcine meat. The goal of the current work was to compare the patterns ...
On the holobiont ‘predictome’ of immunocompetence in pigs
(BMC, 2023-05-01)
Background
Gut microbial composition plays an important role in numerous traits, including immune response. Integration of host genomic information with microbiome data is a natural step in the prediction ...
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 ...
Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
(BMC, 2017-12-01)
Background: Improving feed efciency (FE) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding ...
Second litter syndrome in Iberian pig breed: factors influencing the performance
(Elsevier, 2022-11-09)
Second litter syndrome (SLS) consists of a loss of prolificacy in the second parity (P2), when a sow presents the same or lower results for litter size than in the first parity (P1). This syndrome has ...
Nutrient supply affects the mRNA expression profile of the porcine skeletal muscle
(BMC, 2017-08-10)
Background: The genetic basis of muscle fat deposition in pigs is not well known. So far, we have only identified a limited number of genes involved in the absorption, transport, storage and catabolism ...
An association analysis between a polymorphism in the SEC24A gene and lipid traits recorded in Duroc pigs
(Taylor & Francis Open Access, 2021-10-05)
By regulating the expression of low-density lipoprotein receptors (LDLR), the SEC24A protein modulates the clearance of plasma cholesterol in mice. The whole-genome sequencing of five Duroc boars that ...
Variability in porcine microRNA genes and its association with mRNA expression and lipid phenotypes
(BMC, 2021-05-04)
Background: Mature microRNAs (miRNAs) play an important role in repressing the expression of a wide range of
mRNAs. The presence of polymorphic sites in miRNA genes and their corresponding 3′UTR binding ...
