Expression analysis of porcine miR-33a/b in liver, adipose tissue and muscle and its potential role in fatty acid metabolism
(Public Library of Science, 2021-01-26)
mir-33a and mir-33b are co-transcribed with the SREBF2 and SREBF1 transcription factors, respectively. The main role of SREBF1 is the regulation of genes involved in fatty acid metabolism, while SREBF2 ...
The value of gut microbiota to predict feed efficiency and growth of rabbits under different feeding regimes
(Nature Research, 2021-09-30)
Gut microbiota plays an important role in nutrient absorption and could impact rabbit feed efciency.
This study aims at investigating such impact by evaluating the value added by microbial information
for ...
Whole-genome sequencing reveals insights into the adaptation of French Charolais cattle to Cuban tropical conditions
(BMC, 2021-01-04)
Background: In the early 20th century, Cuban farmers imported Charolais cattle (CHFR) directly from France. These
animals are now known as Chacuba (CHCU) and have become adapted to the rough environmental ...
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 ...
Comparative Transcriptome Profile between Iberian Pig Varieties Provides New Insights into Their Distinct Fat Deposition and Fatty Acids Content
(MDPI, 2021-02-27)
The high deposition of intramuscular fat and the content of oleic fatty acid are characteristic of the Iberian pig. These two parameters present great variability and are differentiated amongst the ...
Leveraging host-genetics and gut microbiota to determine immunocompetence in pigs
(BMC, 2021-10-24)
Background: The gut microbiota infuences host performance playing a relevant role in homeostasis and function of
the immune system. The aim of the present work was to identify microbial signatures ...
Early socialization and environmental enrichment of lactating piglets affects the caecal microbiota and metabolomic response after weaning
(Nature Research, 2021-03-17)
The aim of this study was to determine the possible impact of early socialization and an enriched neonatal environment to improve adaptation of piglets to weaning. We hypothesized that changes in the ...
Describing variability in pig genes involved in coronavirus infections for a One Health perspective in conservation of animal genetic resources
(Nature Research, 2021-02-09)
Coronaviruses silently circulate in human and animal populations, causing mild to severe diseases. Therefore, livestock are important components of a “One Health” perspective aimed to control these viral ...
Variability in porcine microRNA genes and its association with mRNA expression and lipid phenotypes
(BMC, 2021-05-04)
Background: Mature microRNAs (miRNAs) play an important role in repressing the expression of a wide range of
mRNAs. The presence of polymorphic sites in miRNA genes and their corresponding 3′UTR binding ...
Understanding host-microbiota interactions in the commercial piglet around weaning
(Nature Research, 2021-12-06)
Weaning is a critical period in the life of pigs with repercussions on their health and welfare and on the
economy of the swine industry. This study aimed to assess the efect of the commercial early ...
