Genomic Variation and Population Structure of Portuguese Native Dog Breeds. [PDF]

Anim Genet
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

Revisiting Genetic Relationships of the Endangered Austrian Turopolje With Balkan and Commercial Pig Breeds Using Genome-Wide SNP Data. [PDF]

Anim Genet
ABSTRACT The endangered Austrian Turopolje (AT) pig population, which originated from six Croatian Turopolje founders imported during the early 1990s, is nowadays preserved through a national conservation project. This study aims to identify genetic relations, genetic distances and migration events between the AT population, four Austrian commercial ...

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed. [PDF]

J Anim Breed Genet
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

Autozygosity islands and ROH patterns in Nellore lineages: evidence of selection for functionally important traits

BMC Genomics, 2018
Background The aim of this study was to assess genome-wide autozygosity in a Nellore cattle population and to characterize ROH patterns and autozygosity islands that may have occurred due to selection within its lineages.

Assessing runs of homozygosity reveals production traits of Kazakh sheep breeds [PDF]

Brazilian Journal of Biology
Sheep breeding in Kazakhstan is one of the main local roles in animal husbandry. This article presents the results of a study of the genetic indicators of sheep breeds in Kazakhstan, in relation to their meat and wool productivity.

Genetic Diversity in the Italian Holstein Dairy Cattle Based on Pedigree and SNP Data Prior and After Genomic Selection

Frontiers in Veterinary Science, 2022
Genetic diversity has become an urgent matter not only in small local breeds but also in more specialized ones. While the use of genomic data in livestock breeding programs increased genetic gain, there is increasing evidence that this benefit may be ...

Genomic inbreeding estimation in small populations: evaluation of runs of homozygosity in three local dairy cattle breeds

Animal, 2016
In the local breeds with small population size, one of the most important problems is the increase of inbreeding coefficient (F). High levels of inbreeding lead to reduced genetic diversity and inbreeding depression.

A New Fractional Order Hold and Its Capability in Frequency Response and Zero Placement

Journal of Applied Mathematics, 2013
This paper introduces a new holder with application on digital control systems. This holder is a combination of fractional order hold (FROH) and zero-order hold (ZOH) that has the capability of both holders and a frequency response better than both of ...

Conservation Genomic Analysis of the Croatian Indigenous Black Slavonian and Turopolje Pig Breeds

Frontiers in Genetics, 2020
The majority of the nearly 400 existing local pig breeds are adapted to specific environments and human needs. The demand for large production quantities and the industrialized pig production have caused a rapid decline of many local pig breeds in recent
