Correlated genetic trends for production and welfare traits in a mouse population divergently selected for birth weight environmental variability
(Elsevier, 2016-05-12)
The objective of this work was to study the changes that, selecting for environmental variability of birth weight (BW), could bring to other interesting traits in livestock such as: survivability at ...
Integrative approach using liver and duodenum RNA-Seq data identifies candidate genes and pathways associated with feed efficiency in pigs
(Springer Nature, 2018-01-11)
This study aims identifying candidate genes and pathways associated with feed efficiency (FE) in pigs. Liver and duodenum transcriptomes of 37 gilts showing high and low residual feed intake (RFI) were ...
The Effects of Weaning Methods on Gut Microbiota Composition and Horse Physiology
(Frontiers Media, 2017-07-25)
Weaning has been described as one of the most stressful events in the life of horses. Given the importance of the interaction between the gut-brain axis and gut microbiota under stress, we evaluated (i) ...
Analysis of porcine IGF2 gene expression in adipose tissue and its effect on fatty acid composition
(Public Library of Science, 2019-08-08)
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 ...
Genome-Wide Association Study Singles Out SCD and LEPR as the Two Main Loci Influencing Intramuscular Fat Content and Fatty Acid Composition in Duroc Pigs
(Public Library of Science, 2016-03-29)
Intramuscular fat (IMF) content and fatty acid composition affect the organoleptic quality and nutritional value of pork. A genome-wide association study was performed on 138 Duroc pigs genotyped with ...
Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
(BMC, 2017-12-01)
Background: Improving feed efciency (FE) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding ...
The effect of a high monounsaturated fat diet on body weight, backfat and loin muscle growth in high and medium-lean pig genotypes
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2012-01-23)
The objective of this study was to evaluate whether the use of a diet rich in oleic acid could have an effect on daily
weight gain, backfat and loin muscle (Longissimus thoracis) depth. One hundred and ...
Detection of homozygous genotypes for a putatively lethal recessive mutation in the porcine argininosuccinate synthase 1 (ASS1) gene
(Wiley, 2019-11-15)
The sequencing of the pig genome revealed the existence of homozygous individuals for a nonsense mutation in the argininosuccinate synthase 1 (ASS1) gene (rs81212146, c.944T>A, L315X). Paradoxically, ...
Interaction of direct and social genetic effects with feeding regime in growing rabbits
(BMC, 2017-07-20)
Background: Most rabbit production farms apply feed restriction at fattening because of its protective efect against digestive diseases that afect growing rabbits. However, it leads to competitive ...
Using genome wide association studies to identify common QTL regions in three different genetic backgrounds based on Iberian pig breed
(PLoS ONE, 2018-03-09)
One of the major limitation for the application of QTL results in pig breeding and QTN identification has been the limited number of QTL effects validated in different animal material. The aim
of the ...
