Genomic selection strategies in animal breeding programs Molecular genetics is an additional tool which provides information for the detection and exploitation of genes or chromosomal regions with large influence on economic traits. This comes from the development of dense maps of linkage disequilibrium among genetic markers for many livestock species. Although each type of genetic marker has advantages and disadvantages, the only polymorphisms with enough density to meet important requirements for gene mapping are the Single Nucleotide Polymorphisms Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013
Genomic selection in dairy cattle breeds in Brazil raditional breeding has generated significant genetic gain over time. However, this strategy falls short of yielding information on the biological processes involved. Additionally, there are great difficulties for the genetic improvement of characteristics which are measured solely in one gender and/or late in the life span of the animal. With the development of DNA chips it became possible maximizing genetic gain by reducing the generation interval and increasing the intensity of selection.

Influence of polymorphisms in the gene encoding the Stearoyl-CoA desaturase (SCD) enzyme on the nutritional quality of milk fat in Gyr and Guzerat cows Recent evidence from observational studies and controlled clinical trials indicates that milk fat, although predominantly saturated, has neutral or positive effects on cardiometabolic health. Such benefits have been attributed to the complex and unique chemical nature of milk fat, which contains several compounds potentially beneficial to health, such as butyric acid (C4:0), vaccenic acid ( trans-11 C18:1), rumenic acid ( cis--9, trans-11 CLA), oleic acid ( cis-9 C18 ...

Detection of selection signatures in cattle using Next Generation Sequencing (NGS) data Selection for desirable phenotypes has been practiced in cattle since their domestication approximately 10,000 years ago. This process, alongside breed development and genetic improvement programs, has led to the vast diversity of cattle breeds known today. Traditional breeding methods, grounded in quantitative theory, have facilitated continuous genetic gains in most economically important traits. However, until recently, selection has been conducted without knowledge of the specific genes infl Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2019
