Domestic estimated breeding values and genomic enhanced breeding values of bulls in comparison with their foreign genomic enhanced breeding values.
Estimated breeding values (EBVs) and genomic enhanced breeding values (GEBVs) for milk production of young genotyped Holstein bulls were predicted using a conventional BLUP - Animal Model, a method fitting regression coefficients for loci (RRBLUP), a method utilizing the realized genomic relationship matrix (GBLUP), by a single-step procedure (ssGBLUP) and by a one-step blending procedure.

متن کاملBreeding Cattle for Mastitis Resistance
The development of an immunological assay where cells isolated from blood are stimulated by an Staphylococcus aureus antigen in vitro is described. Variation was observed in the ability of cells isolated from young cattle, cows and bulls to respond in vitro to S. aureus, suggesting that differences in immune responsiveness may be measured by this method. Bull progeny groups were shown to have c...
متن کاملEffect of Markers Effect Estimation Methods, Population Structure and Trait Architercture on the Accuracy of Genomic Breeding Values
This study aimed to investigate the effect of the method of estimating the effects of markers , QTLs distribution, number of QTLs, effective population size and trait heritability on the accuracy of genomic predictions. Two effective population sizes, 100 and 500 individuals, were simulated by QMSim software. A 100 cM genome including one chromosome was simulated where 500 SNPs and two diffe...
متن کاملGenomic heritabilities and genomic estimated breeding values for methane traits in Angus cattle.
Enteric methane emissions from beef cattle are a significant component of total greenhouse gas emissions from agriculture. The variation between beef cattle in methane emissions is partly genetic, whether measured as methane production, methane yield (methane production/DMI), or residual methane production (observed methane production - expected methane production), with heritabilities ranging ...
متن کاملGenomic-assisted prediction of breeding values: Indications of its effectiveness
A massive quantity of genomic information is now available in livestock. For example, 2.8 million single-nucleotide polymorphisms (SNPs) have been found in the chicken genome. It is natural to consider use of this information as an aid in genetic improvement of livestock or plants. In medicine and agriculture, for example, genomic information could also be used for designing, e.g., diet or plan...
