Hierarchy Establishment in Growing Finishing Pigs: Impacts on Behavior, Growth Performance, and Physiological Parameters
(MDPI, 2023-01-14)
Pigs are social animals that live in groups with well-established social structures and have always been a key species in debates over farm animal welfare. However, intensive production systems often ...
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 ...
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 ...
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 ...
Analysis of the causal structure of traits involved in sow lactation feed efficiency
(BMC, 2022-07-26)
Background
Feed efficiency during lactation involves a set of phenotypic traits that form a complex system, with some traits exerting causal effects on the others. Information regarding such ...
Identification of transcriptional regulatory variants in pig duodenum, liver, and muscle tissues
(Oxford University Press, 2023-06-24)
Background
In humans and livestock species, genome-wide association studies (GWAS) have been applied to study the association between variants distributed across the genome and a phenotype of interest. ...
Feature Selection Stability and Accuracy of Prediction Models for Genomic Prediction of Residual Feed Intake in Pigs Using Machine Learning
(Frontiers Media, 2021-02-22)
Feature selection (FS, i.e., selection of a subset of predictor variables) is essential in high-dimensional datasets to prevent overfitting of prediction/classification models and reduce computation ...
Characterization of the Maternally Derived Antibody Immunity against Rhdv-2 after Administration in Breeding Does of an Inactivated Vaccine
(MDPI, 2020-08-28)
Inactivated strain-specific vaccines have been successfully used to control rabbit haemorrhagic disease (RHD) caused by RHDV-2 in the rabbit industry. It is unknown whether and how vaccination of breeding ...
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 ...
