Genome scan for meat quality traits in Nelore beef cattle.
Meat quality traits are economically important because they affect consumers' acceptance, which, in turn, influences the demand for beef. However, selection to improve meat quality is limited by the small numbers of animals on which meat tenderness can be evaluated due to the cost of performing shear force analysis and the resultant damage to the carcass. Genome wide-association studies for War...
متن کاملGenetic mapping of quantitative trait loci for meat quality and muscle metabolic traits in cattle.
A whole-genome scan was carried out in New Zealand and Australia to detect quantitative trait loci (QTL) for live animal and carcass composition traits and meat quality attributes in cattle. Backcross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass ...
متن کاملFine mapping of quantitative trait loci underlying sensory meat quality traits in three French beef cattle breeds.
Improving the traits that underlie meat quality is a major challenge in the beef industry. The objective of this paper was to detect QTL linked to sensory meat quality traits in 3 French beef cattle breeds. We genotyped 1,059, 1,219, and 947 young bulls and their sires belonging to the Charolais, Limousin, and Blonde d'Aquitaine breeds, respectively, using the Illumina BovineSNP50 BeadChip (Ill...
متن کاملIdentification of quantitative trait loci in beef cattle*
The objective of this review is to describe the quantitative trait loci (QTL) identified in beef cattle at the U. S. Meat Animal Research Center (MARC), and to describe the process in which they can be incorporated into animal breeding schemes. Four large half-sib families were developed (two families with 500 offspring each, and two families with an average of 227 offspring) to detect QTL for ...
متن کاملBovine quantitative trait loci analysis for growth, carcass, and meat quality traits in an F2 population from a cross between Japanese Black and Limousin.
A genome-wide scan for QTL affecting economically important traits in beef production was performed using an F(2) resource family from a Japanese Black x Limousin cross, where 186 F(2) animals were measured for growth, carcass, and meat-quality traits. All family members were genotyped for 313 informative microsatellite markers that spanned 2,382 cM of bovine autosomes. The centromeric region o...
