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 کاملCandidate genes for production traits in Nelore beef cattle.
Meat quality is an important trait for the beef industry. Backfat thickness, ribeye area, and shear force are traits measured late in life, and the investigation of molecular markers associated with these traits can help breeding programs. In cattle, some polymorphisms have been related to production traits. Thus, the purpose of this study was to assess the presence of polymorphisms in the...
متن کاملEstimates of Genetic Correlations between Carcass and Growth Traits and Scrotal Circumference in Nelore Cattle
INTRODUCTION The demand for high quality meat and the competition with other protein sources imposes the introduction of new technologies in the Brazilian beef cattle system of production. Most of breeding evaluation programs in Brazil, have given emphasis to records of weights and scrotal circumference (SC) at different ages, ignoring carcass traits (CT) and other growth traits. Carcass traits...
متن کاملNetwork Analysis Reveals Putative Genes Affecting Meat Quality in Angus Cattle
Improvements in eating satisfaction will benefit consumers and should increase beef demand which is of interest to the beef industry. Tenderness, juiciness, and flavor are major determinants of the palatability of beef and are often used to reflect eating satisfaction. Carcass qualities are used as indicator traits for meat quality, with higher quality grade carcasses expected to relate to more...
متن کاملAccuracy of genomic breeding values in multibreed beef cattle populations derived from deregressed breeding values and phenotypes.
Genomic selection involves the assessment of genetic merit through prediction equations that allocate genetic variation with dense marker genotypes. It has the potential to provide accurate breeding values for selection candidates at an early age and facilitate selection for expensive or difficult to measure traits. Accurate across-breed prediction would allow genomic selection to be applied on...
