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 ...
Admixture and breed traceability in European indigenous pig breeds and wild boar using genome-wide SNP data
(Nature Research, 2022-05-05)
Preserving diversity of indigenous pig (Sus scrofa) breeds is a key factor to (i) sustain the pork chain (both at local and global scales) including the production of high-quality branded products, (ii) ...
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 ...
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. ...
Mutations on a conserved distal enhancer in the porcine C-reactive protein gene impair its expression in liver
(Frontiers Media, 2023-09-14)
C-reactive protein (CRP) is an evolutionary highly conserved protein. Like humans, CRP acts as a major acute phase protein in pigs. While CRP regulatory mechanisms have been extensively studied in humans, ...
Multi-Criteria Evaluation Model of Management for Weaned Piglets and Its Relations with Farm Performance and Veterinary Medicine Consumption
(MDPI, 2023-11-14)
Weaned piglets, being immature, demand careful handling to mitigate post-weaning stress in order to avoid immunosuppression and the use of antimicrobials to palliate the effects of disease outbreaks due ...
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 ...
Role of AMPK signalling pathway during compensatory growth in pigs
(BioMed Central, 2018-09-17)
Background: The molecular basis of compensatory growth in monogastric animals has not yet been fully explored.
Herewith, in this study we aim to determine changes in the pig skeletal muscle transcriptome ...
Segregation of Regulatory Polymorphisms with Effects on the Gluteus Medius Transcriptome in a Purebred Pig Population
(Public Library of Science, 2012-04-24)
Background: The main goal of the present study was to analyse the genetic architecture of mRNA expression in muscle, a
tissue with an outmost economic importance for pig breeders. Previous studies have ...
