Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Genomic inbreeding coefficients using imputation genotypes: Assessing the effect of ancestral genotyping in Holstein-Friesian dairy cows

open access: yesJournal of Dairy Science
The objective of this study was to assess the effect of using or not using the genotypes of the parents of a cow for imputing SNPs on the estimation of genomic inbreeding coefficients of cows. Imputation (i.e., genotyped plus imputed) genotypes from 68,127 Italian Holstein dairy cows registered in the Italian National Association of Holstein, Brown ...

Comparative evaluation of genomic inbreeding parameters in seven commercial and autochthonous pig breeds

open access: yesAnimal, 2020
Single nucleotide polymorphism (SNP) genotyping tools, which can analyse thousands of SNPs covering the whole genome, have opened new opportunities to estimate the inbreeding level of animals directly using genome information.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Use of Cluster Analysis for Identifying Metafounders

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ$$ \boldsymbol{\Gamma} $$ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A$$ \mathbf{A} $$, creating matrix AΓ$$ {\mathbf{A}}^{\boldsymbol{\Gamma}} $$.

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

Analysis of the Genetic Relationship and Inbreeding Coefficient of the Hetian Qing Donkey through a Simplified Genome Sequencing Technology

open access: yesGenes
The Hetian Qing donkey is an excellent local donkey breed in Xinjiang. It is of great significance to accelerate breeding and the speed of breeding and rejuvenation, as well as to understand the genetic basis of the strategies and population. This study collected a total of 4 male donkeys and 28 female donkeys.

Genetic variability in a Holstein population using SNP markers and their use for monitoring mating strategies

open access: yesRevista Mexicana de Ciencias Pecuarias, 2019
As genotyping costs continue to decrease, the demand for genotyping has increased among farmers. In most livestock herds, an important issue is controlling the increase in inbreeding coefficient.
