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 ...
Study of using marker assisted selection on a beef cattle breeding program by model comparison
(Elsevier, 2012-03-31)
A data set of a commercial Nellore beef cattle selection program was used to compare
breeding models that assumed or not markers effects to estimate the breeding values,
when a reduced number of animals ...
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, ...
A pilot RNA-seq study in 40 pietrain ejaculates to characterize the porcine sperm microbiome
(Elsevier, 2020-08-15)
The microbiome plays a key role in homeostasis and health and it has been also linked to fertility and semen quality in several animal species including swine. Despite the more than likely importance ...
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 ...
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 ...
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 ...
Efect of feed restriction on the environmental variability of birth weight in divergently selected lines of mice
(BMC, 2019-06-13)
Selection of mice for decreased environmental variability of birth weight has achieved higher survivability and larger litter size as a correlated response to canalized selection, which suggests higher ...
