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 ...
Expression analysis of candidate genes for fatty acid composition in adipose tissue and identifcation of regulatory regions
(Nature Research, 2018-02-01)
The aim of this work was to study the genetic basis of the backfat expression of lipid-related genes
associated with meat quality traits in pigs. We performed a genome-wide association study with ...
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, ...
Second litter syndrome in Iberian pig breed: factors influencing the performance
(Elsevier, 2022-11-09)
Second litter syndrome (SLS) consists of a loss of prolificacy in the second parity (P2), when a sow presents the same or lower results for litter size than in the first parity (P1). This syndrome has ...
Genetic parameters and direct, maternal and heterosis effects on litter size in a diallel cross among three commercial varieties of Iberian pig
(Elsevier, 2019-06-04)
The Iberian pig is one of the pig breeds that has the highest meat quality. Traditionally, producers have bred one of the available varieties, exclusively, and have not used crosses between them, which ...
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 ...
Single-step genome-wide association study for social genetic effects and direct genetic effects on growth in Landrace pigs
(Nature Research, 2020-09-11)
In livestock social interactions, social genetic effects (SGE) represent associations between phenotype of one individual and genotype of another. Such associations occur when the trait of interest is ...
Genetic variability of functional longevity in five rabbit lines
(Cambridge University Press, 2020-01-22)
The objectives of this study were to analyse the differences in the genetic determination of functional longevity in five Spanish lines of rabbits and to check how different systematic factors might ...
SNP co-association and network analyses identify E2F3, KDM5A and BACH2 as key regulators of the bovine milk fatty acid profile
(Nature Research, 2017-12-11)
The fatty acid (FA) profle has a considerable impact on the nutritional and technological quality of milk
and dairy products. The molecular mechanism underlying the regulation of fat metabolism in ...
Association between the pig genome and its gut microbiota composition
(Nature Research, 2019-06-19)
The gut microbiota has been evolving with its host along the time creating a symbiotic relationship. In this study, we assess the role of the host genome in the modulation of the microbiota composition ...
