Genetic parameters and associated genomic regions for global immunocompetence and other health-related traits in pigs
(Nature Research, 2020-10-28)
The inclusion of health-related traits, or functionally associated genetic markers, in pig breeding programs could contribute to produce more robust and disease resistant animals. The aim of the present ...
Co-expression network analysis predicts a key role of microRNAs in the adaptation of the porcine skeletal muscle to nutrient supply
(BMC, 2020-01-17)
Background
The role of non-coding RNAs in the porcine muscle metabolism is poorly understood, with few studies investigating their expression patterns in response to nutrient supply. Therefore, we aimed ...
Maternal Transmission Ratio Distortion in Two Iberian Pig Varieties
(MDPI, 2020-09-05)
Transmission ratio distortion (TRD) is defined as the allele transmission deviation from the heterozygous parent to the offspring from the expected Mendelian genotypic frequencies. Although TRD can be ...
Priming for welfare: gut microbiota is associated with equitation conditions and behavior in horse athletes
(Nature Research, 2020-05-20)
We simultaneously measured the fecal microbiota and multiple environmental and host-related variables in a cohort of 185 healthy horses reared in similar conditions during a period of eight months. 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 ...
Breeding farm, level of feeding and presence of antibiotics in the feed influence rabbit cecal microbiota
(BMC, 2020-11-02)
Background
The effect of the production environment and different management practices in rabbit cecal microbiota remains poorly understood. While previous studies have proved the impact of the age or ...
Machine Learning Prediction of Crossbred Pig Feed Efficiency and Growth Rate From Single Nucleotide Polymorphisms
(Frontiers Media, 2020-12-18)
This research assessed the ability of a Support Vector Machine (SVM) regression model to predict pig crossbred (CB) performance from various sources of phenotypic and genotypic information for improving ...
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 ...
Identification of strong candidate genes for backfat and intramuscular fatty acid composition in three crosses based on the Iberian pig
(Nature Research, 2020-08-18)
Meat quality has an important genetic component and can be modified by the fatty acid (FA) composition and the amount of fat contained in adipose tissue and muscle. The present study aimed to find genomic ...
Genome-wide association study for feed efficiency in collective cage-raised rabbits under full and restricted feeding
(Wiley, 2020-07-22)
Feed efficiency (FE) is one of the most economically and environmentally relevant traits in the animal production sector. The objective of this study was to gain knowledge about the genetic control of ...
