Use of group records of feed intake to select for feed efficiency in rabbit
(Journal of Animal Breeding and Genetics, 2019-04-24) Genètica i Millora Animal
Models for genetic evaluation of feed efficiency (FE) for animals housed in groups when they are either fed ad libitum (F) or on restricted (R) feeding were implemented. Definitions of FE on F included ...
Inbreeding depression load for litter size in Entrepelado and Retinto Iberian pig varieties
(Journal of Animal Science, 2019-03-14) Genètica i Millora Animal
Individual-specific hidden inbreeding depression load (IDL) can be accounted for in livestock populations by appropriate best linear unbiased prediction approaches. This genetic effect has a recessive ...
Genetic parameters of sow feed efficiency during lactation and its underlying traits in a Duroc population
(animal, 2019-11-25) Genètica i Millora Animal
As a result of the genetic selection for prolificacy and the improvements in the environment and farms management, litter size has increased in the last few years so that energy requirements of the ...
Discovery and annotation of novel microRNAs in the porcine genome by using a semi-supervised transductive learning approach
(Genomics, 2019-12-06) Genètica i Millora Animal
Despite the broad variety of available microRNA (miRNA) prediction tools, their application to the discovery and annotation of novel miRNA genes in domestic species is still limited. In this study we ...
Bayesian hierarchical model for comparison of different nonlinear function and genetic parameter estimates of meat quails
(Poultry Science, 2018-12-07) Genètica i Millora Animal
This study aimed to compare different nonlinear functions to describe the growth curve of European quails and to estimate growth curve parameters, (co)variance components, and genetic and systematic ...
Differential expression of mRNA isoforms in the skeletal muscle of pigs with distinct growth and fatness profiles
(BMC Genomics, 2018-02-14) Genètica i Millora Animal
Background: The identification of genes differentially expressed in the skeletal muscle of pigs displaying distinct
growth and fatness profiles might contribute to identify the genetic factors that ...
Diversity across major and candidate genes in European local pig breeds
(PLoS ONE, 2018-11-20) Genètica i Millora Animal
The aim of this work was to analyse the distribution of causal and candidate mutations associated to relevant productive traits in twenty local European pig breeds. Also, the potential of the SNP panel ...
Polymorphisms of the cryptochrome 2 and mitoguardin 2 genes are associated with the variation of lipid-related traits in Duroc pigs
(Scientific Reports, 2019-06-21) Genètica i Millora Animal
The genetic factors determining the phenotypic variation of porcine fatness phenotypes are still largely
unknown. We investigated whether the polymorphism of eight genes (MIGA2, CRY2, NPAS2, CIART,
ARNTL2, ...
Analysis of porcine IGF2 gene expression in adipose tissue and its effect on fatty acid composition
(Plos One, 2019-08-08) Genètica i Millora Animal
IGF2:g.3072G>A polymorphism has been described as the causal mutation of a maternally imprinted QTL for muscle growth and fat deposition in pigs. The objective of the current work was to study the ...
Genetic diversity and selection signatures of the beef ‘Charolais de Cuba’ breed
(Scientific Reports, 2018-07-20) Genètica i Millora Animal
In this study, we used BovineSNP50 Genotyping BeadChip data to estimate the structure, putative
ancestral origin as well as to identify regions with selective sweeps that may have had an important
role ...
