Genetic diversity of European livestock breeds. This book contains the first report of the animal genetic data bank, based at Hannover, of the European Association of Animal production. It contains information on breeds of cattle, sheep, pigs, goats and by: However, as regards the proportion of native breeds endangered, the target should be zero if the loss of genetic diversity is to be halted.
At this stage, the livestock genetic diversity indicator should be interpreted with care because: (i) there is still no agreement among countries on the definition of 'native' and 'non-native' breeds. Nei’s genetic distances 30 between studied breeds range from the minimum value of (observed between Alentejana and Iberian breeds) to the maximum value of (observed between Apulo Cited by: 3.

Despite growing interest in safeguarding biodiversity of livestock and poultry, genetic erosion continues. The Scottish Highland Cattle is a hardy breed that thrives in harsh environments.
It is frequently used for conservation grazing as it eats plants that many other cattle avoid. 27 JanuaryRome - Livestock keepers and policy makers worldwide are increasingly interested in harnessing animal biodiversity.
Although most of the genetic diversity is explained within breeds, the global estimate of F st (13%) is quite high compared to the 7–11% reported for European cattle breeds (MacHugh et Cited by: In this study, we characterized genetic diversity in the gene bank for Dutch native cattle breeds.
A total of bulls from seven native breeds and a sample of Holstein Friesian bulls were included. Genotype data were used to calculate genetic similarities.
Based on these similarities, most breeds were clearly differentiated, except for two breeds (Deep Red and Improved Red and White Author: Anouk E.

We hope you enjoy the information provided and find it both educational and fun. DAD-IS provides you with tools to monitor national breed populations and with this, to make informed decisions on the management of animal genetic resources. More than 15 national breed populations (representing more than 8 breeds and about 40 species) from countries are recorded.
Breeds under strict artificial selection and indigenous breeds under traditional breeding schemes were included.
The overall results showed that the genetic diversity is widespread in Buša breeds in the Anatolian and Balkan areas, when compared with the alpine and north‐western European by: The present indicator shows the share of breeding female population between introduced and native breed species (namely, cattle and sheep) per country, as a proxy to assess the genetic diversity of these species.
In addition, it shows the proportion of native breeds which is threatened due to low breeding female population. A germplasm collection curated by the United States Department of Agriculture (USDA), Agricultural Research Service (ARS), National Animal Germplasm Program contains of over one million samples from o animals, representing livestock and poultry breeds.
The collection was developed to provide genetic conservation and security for the U.S. livestock : Harvey D. Blackburn, Carrie S. Wilson, Bethany Krehbiel. Maintaining genetic variation is crucial if we want to continue to improve our livestock and respond to changes in climate, disease or consumer preferences.
The following article by Sarah Blott, John Williams and Chris Haley describes work at the Roslin Institute on the evaluation of genetic diversity in European cattle breeds.
Genetic diversity and population structure of 20 north European cattle breeds. Autochthonous cattle breeds are an important source of genetic variation because they might carry alleles that enable them to adapt to local environment and food conditions.
Original Braunvieh (OB) is a local cattle breed of Switzerland used for beef and milk production in alpine areas. Using whole-genome sequencing (WGS) data of 49 key ancestors, we characterize genomic diversity, genomic.
Information about genetic diversity and population structure among cattle breeds is essential for genetic improvement, understanding of environmental adaptation as well as utilization and conservation of cattle breeds.
This study investigated genetic diversity and the population structure among six cattle breeds in South African (SA) including Afrikaner (n = 44), Nguni (n = 54), Drakensberger Cited by: Genetic divergence of the Spanish cattle breeds and within-population genetic diversity are the combined result of breed origin, founder effects, population size, genetic drift, and admixture.
As shown here, this may lead to inbreeding and low genetic by: Genetic diversity measures of local European beef cattle breeds for conservation purposes.
This study was undertaken to determine the genetic structure, evolutionary relationships, and the genetic diversity among 18 local cattle breeds from Spain, Portugal, and France using 16 microsatellites.
Heterozygosities, estimates of Fst, genetic distances, multivariate and diversity analyses, and assignment tests were performed. Heterozygosities ranged from in the Pirenaica breed Cited by: Abstract. Blood samples were collected from animals from 15 indigenous, 2 old imported, and 3 commercial North European cattle breeds.
The samples were analyzed for 11 erythrocyte antigen systems, 8 proteins, and 10 microsatellites, and used to assess inter- and intrabreed genetic variation and genetic population by: between Bu a cattle breeds with the aim to design adequate breeding programs and preserving strategies.
As the genetic diversity is a global objective, we put our results into the context of European cattle diversity here represented by 20 cattle breeds. To ensure the accuracy of genotyping and to further avoid accidental confusion of samples we.

In a study of the genetic structure and population dynamics of a unique breed of cattle that is indigenous to Southeastern Europe, researchers have discovered a remarkable degree of genetic variation. China exhibits a great diversity of ecosystems and abundant cattle resources, with nearly 30 million cattle from 53 indigenous breeds reared in specific geographic regions.
To explore the genetic diversity and population structure of Chinese indigenous cattle, a population genetic analysis at both the individual and population levels was conducted and the admixture analysis was by: 5.

The sample comprised 68 European domestic breeds (and lines), including 29 local breeds, 18 varieties of major international breeds, namely Duroc, Hampshire, Landrace, Large White and Piétrain, and 21 commercial lines either purebred or synthetic, to which the Chinese Meishan and a sample of European Cited by: The first herd books were opened in England in the nineteenth century, encouraging breeders to standardize appearance and improve production.

breeds across Europe are well known for. Native cattle breeds are important genetic resources given their adaptation to the local environment in which they are bred. However, the widespread use of commercial cattle breeds has resulted in a marked reduction in population size of several native cattle breeds worldwide.
Therefore, conservation management of native cattle breeds requires urgent attention to avoid their by: 2.
The genetic diversity of livestock can play a vital role in feeding the world in the face of hotter weather and the other effects of climate change, yet many valuable breeds continue to be at risk. Genetic Concentration: Starbuck.
Intensive livestock operations also threaten breed diversity by narrowing the genetic base of popular breeds. Hanoverhill Starbuck, a Canadian Holstein bull, is one example of this genetic concentration. Considered to be near-perfect, Starbuck and his sons and daughters have been widely praised.
