Genomic differentiation among varieties of Iberian pig
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2020-02-26)
Aim of study: The objective of this study was to identify the autosomal genomic regions associated with genetic differentiation between three commercial strains of Iberian pig.
Area of study: Extremadura ...
Social network analysis of agonistic behaviour and its association with economically important traits in pigs
(MDPI, 2020-11-16)
Aggression behaviour has several negative consequences on the performance and welfare of pigs. Here, the Social Network Analysis (SNA) approach was employed to (1) identify individual traits that describe ...
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 ...
Whole-genome sequencing of European autochthonous and commercial pig breeds allows the detection of signatures of selection for adaptation of genetic resources to different breeding and production systems
(BMC, 2020-06-26)
Background
Natural and artificial directional selection in cosmopolitan and autochthonous pig breeds and wild boars have shaped their genomes and resulted in a reservoir of animal genetic diversity. ...
Effects of a high-fat-diet supplemented with probiotics and ω3-fatty acids on appetite regulatory neuropeptides and neurotransmitters in a pig model
(Wageningen Academic Publishers, 2020-07-28)
The pig is a valuable animal model to study obesity in humans due to the physiological similarity between humans and pigs in terms of digestive and associated metabolic processes. The dietary use of ...
Identification of eQTLs associated with lipid metabolism in Longissimus dorsi muscle of pigs with different genetic backgrounds
(Nature Research, 2020-06-17)
Intramuscular fat content and its fatty acid composition affect porcine meat quality and its nutritional value. The present work aimed to identify genomic variants regulating the expression in the porcine ...
Gut eukaryotic communities in pigs: diversity, composition and host genetics contribution
(BMC, 2020-05-07)
Background
The pig gut microbiome harbors thousands of species of archaea, bacteria, viruses and eukaryotes such as protists and fungi. However, since the majority of published studies have been focused ...
Networks of inbreeding coefficients in a selected population of rabbits
(Wiley, 2020-08-17)
The correlation between pedigree and genomic‐based inbreeding coefficients is usually discussed in the literature. However, some of these correlations could be spurious. Using partial correlations and ...
The Identification of Runs of Homozygosity Gives a Focus on the Genetic Diversity and Adaptation of the “Charolais de Cuba” Cattle
(MDPI, 2020-11-27)
Inbreeding and effective population size (Ne) are fundamental indicators for the management and conservation of genetic diversity in populations. Genomic inbreeding gives accurate estimates of inbreeding, ...
Genome‐wide detection of copy number variants in European autochthonous and commercial pig breeds by whole‐genome sequencing of DNA pools identified breed‐characterising copy number states
(Wiley, 2020-06-08)
In this study, we identified copy number variants (CNVs) in 19 European autochthonous pig breeds and in two commercial breeds (Italian Large White and Italian Duroc) that represent important genetic ...
