Sutarno (2010) Genetic variations among Indonesian native cattle breeds based on polymorphisms analysis in the growth hormone loci and mitochondrial DNA. Biodiversitas 11: 1-5. Genetic variation within breeds is important and its study has become a subject of interest in livestock species, as it has many applications in animal breeding and genetics, such as the identification of animals and par...
The number of breeds of domesticated animals, especially livestock, have declined rapidly. The proximate causes and processes involved in loss of breeds are outlined. Also the path-dependent effect and Swanson’s dominance-effect are discussed in relation to lock-in of breed selection. While these effects help to explain genetic erosion, they need to be supplemented to provide further explanatio...
The introduction of livestock species in Europe has been followed by various genetic events, which created a complex spatial pattern of genetic differentiation. Spatial principal component (sPCA) analysis and spatial metric multidimensional scaling (sMDS) incorporate geography in multivariate analysis. This method was applied to three microsatellite data sets for 45 goat breeds, 46 sheep breeds...
We have investigated the origin of swine breeds through the joint analysis of mitochondrial, microsatellite, and Y-chromosome polymorphisms in a sample of pigs and wild boars with a worldwide distribution. Genetic differentiation between pigs and wild boars was remarkably weak, likely as a consequence of a sustained gene flow between both populations. The analysis of nuclear markers evidenced t...
Following domestication, livestock breeds have experienced intense selection pressures for the development of desirable traits. This has resulted in a large diversity of breeds that display variation in many phenotypic traits, such as coat colour, muscle composition, early maturity, growth rate, body size, reproduction, and behaviour. To better understand the relationship between genomic compos...
When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still critical component of animal breeding Laos. Thus, there a need to review previous, current situation prospects for Laos' production. It aimed study different traits among existing dominant improved (cattle, pig, goat) more in-depth on sector's previous evolving prospects. Our findings re...
In situ conservation of local breeds requires populations in economically sustainable and resilient production systems. those countries where the market recognizes quality products breeds, traditional relationship between can be used to improve breed profitability. We analyze sales data from year 2020 five dairy associated with endangered farmed northern Italy, order understand potential resili...
There is considerable interest in locally adapted breeds of livestock as reservoirs of genetic diversity that may provide important fitness traits for future use in agriculture. In marginal areas, these animals contribute to food security and extract value from land unsuitable for other systems of farming. In England, close to 50% of the national sheep flock is farmed on grassland designated as...
Information on genetic structure and variability of livestock breeds is critical for efficient conservation plans. Here we present molecular characterization of 5 Indian grey colored cattle breeds from northern and western parts of India on the basis of 21 FAO recommended microsatellite markers. Kankrej breed has its native tract in the state of Gujarat, Tharparkar, Nagori and Mewati in Rajasth...
This review compiles the results of 21 genomic studies of European Bos taurus breeds and thus provides a general picture of the selection signatures in taurine cattle identified by genome-wide selection-mapping scans. By performing a comprehensive summary of the results reported in the literature, we compiled a list of 1049 selection sweeps described across 37 cattle breeds (17 beef breeds, 14 ...
