Competing risk analyses of longevity in Duroc sows with a special emphasis on leg conformation
(Elsevier, 2009-01-01)
A competing risk approach was used to evaluate the influence of several factors on culling risk for 587 Duroc sows. Three
different analyses were performed according to whether sow failure was due to ...
Genomic selection of purebreds for crossbred performance
(BMC, 2009-01-15)
Background: One of the main limitations of many livestock breeding programs is that selection is
in pure breeds housed in high-health environments but the aim is to improve crossbred
performance under ...
Genetic comparison of milk production and composition in three maternal rabbit lines
(Universidad Politécnica de Valencia, 2014-12-18)
The aim of this study was to compare 3 Spanish maternal rabbit lines (A, V and LP) in terms of milk production and composition. These lines were founded on different criteria but selected for litter ...
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 ...
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 ...
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 ...
Identification of strong candidate genes for backfat and intramuscular fatty acid composition in three crosses based on the Iberian pig
(Nature Research, 2020-08-18)
Meat quality has an important genetic component and can be modified by the fatty acid (FA) composition and the amount of fat contained in adipose tissue and muscle. The present study aimed to find genomic ...
Identification of candidate regulatory genes for intramuscular fatty acid composition in pigs by transcriptome analysis
(BMC, 2024-02-12)
Background
Intramuscular fat (IMF) content and its fatty acid (FA) composition are typically controlled by several genes, each with a small effect. In the current study, to pinpoint candidate genes and ...
A genome-wide association analysis for porcine serum lipid traits reveals the existence of age-specific genetic determinants
(BMC, 2014-09-04)
Background: The genetic determinism of blood lipid concentrations, the main risk factor for atherosclerosis, is practically unknown in species other than human and mouse. Even in model organisms, little ...
