A functional regulatory variant of MYH3 influences muscle fiber-type composition and intramuscular fat content in pigs
(Public Library of Science, 2019-10-11)
Muscle development and lipid accumulation in muscle critically affect meat quality of livestock. However, the genetic factors underlying myofiber-type specification and intramuscular fat (IMF) accumulation ...
Identification of rumen microbial biomarkers linked to methane emission in Holstein dairy cows
(Wiley, 2019-08-16)
Mitigation of greenhouse gas emissions is relevant for reducing the environmental impact of ruminant production. In this study, the rumen microbiome from Holstein cows was characterized through a ...
Analysis of porcine adipose tissue transcriptome reveals differences in de novo fatty acid synthesis in pigs with divergent muscle fatty acid composition
(BMC, 2013-12-01)
Background: In pigs, adipose tissue is one of the principal organs involved in the regulation of lipid metabolism.
It is particularly involved in the overall fatty acid synthesis with consequences in ...
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 ...
Variability-specific differential gene expression across reproductive stages in sows
(Elsevier, 2013-10-11)
Differential gene expression analyses typically focus on departures across mathematical expectations (i.e. mean) from two or more groups of microarrays, without considering alternative patterns of ...
Selection of Internal Control Genes for Real-Time Quantitative PCR in Ovary and Uterus of Sows across Pregnancy
(Public Library of Science, 2013-06-13)
Background: Reproductive traits play a key role in pig production in order to reduce costs and increase economic returns. Among others, gene expression analyses represent a useful approach to study ...
Breeding programmes to improve male reproductive performance and efficiency of insemination dose production in paternal lines: feasibility and limitations
(Universidad Politécnica de Valencia, 2013-06-26)
This paper reviews the current genetic knowledge on issues related with the efficient use of bucks
in artificial insemination (AI). Differences between lines have been found to be relevant in semen ...
An association analysis for 14 candidate genes mapping to meat quality quantitative trait loci in a Duroc pig population reveals that the ATP1A2 genotype is highly associated with muscle electric conductivity
(Wiley, 2019-10-21)
In previous GWAS carried out in a Duroc commercial line (Lipgen population), we detected on pig chromosomes 3, 4 and 14 several QTL for gluteus medius muscle redness (GM a*), electric conductivity in ...
Genome data from a sixteenth century pig illuminate modern breed relationships
(Springer Nature, 2014-09-10)
Ancient DNA (aDNA) provides direct evidence of historical events that have modeled the genome of modern individuals. In livestock, resolving the differences between the effects of initial domestication ...
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 ...
