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 ...
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 ...
Indirect genetic effect model using feeding behaviour traits to define the degree of interaction between mates: an implementation in pigs growth rate
(Cambridge University Press, 2018-06-06)
An alternative implementation of the animal model including indirect genetic effect (IGE) is presented considering pair-mate-specific interaction degrees to improve the performance of the model. Data ...
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 ...
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 ...
Selection for environmental variance of litter size in rabbits
(BMC, 2017-05-22)
Background
In recent years, there has been an increasing interest in the genetic determination of environmental variance. In the case of litter size, environmental variance can be related to the capacity ...
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 ...
Lactating performance, water and feed consumption of rabbit does reared under a Mediterranean summer circadian cycle of temperature v. comfort temperature conditions
(Elsevier, 2015-01-16)
The general aim of this research was to study the effect of high ambient temperature on the performance of does during lactation, specifically the following factors: average daily feed (ADFI) and water ...
