Genome wide scan for somatic cell counts in holstein bulls
BACKGROUND Mastitis is the most costly disease for dairy production, and control of the disease is often difficult, due to its multi-factorial nature. Susceptibility to mastitis is under partial genetic control and the industry uses indirect selection for decreased concentrations of somatic cells in milk to reduce mastitis. METHODS A genome-wide scan was performed to identify genomic regions ...
متن کاملA whole genome scan to map QTL for milk production traits and somatic cell score in Canadian Holstein bulls.
The detection and mapping of genetic markers linked to quantitative trait loci (QTL) can be utilized to enhance genetic improvement of livestock populations. With the completion of the bovine genome sequence assembly, single nucleotide polymorphisms (SNP) assays spanning the whole bovine genome and research work on large scale identification, validation and analysis of genotypic variation in ca...
متن کاملRelationships between evaluations of Canadian and USA Holstein bulls for longevity and somatic cell score
Canadian and United States evaluations of Holstein bulls were compared for longevity and somatic cell score. A total of 13 236 bulls was evaluated for longevity with 462 bulls having evaluations in both countries, and 10 945 bulls evaluated for somatic cell score with 564 bulls having evaluations in both countries. Multiple across country evaluation procedures were used to estimate the genetic ...
متن کاملA genome-wide scan for signatures of recent selection in Holstein cattle.
The data from the newly available 50 K SNP chip was used for tagging the genome-wide footprints of positive selection in Holstein-Friesian cattle. For this purpose, we employed the recently described Extended Haplotype Homozygosity test, which detects selection by measuring the characteristics of haplotypes within a single population. To assess formally the significance of these results, we com...
متن کاملA whole-genome scan to map quantitative trait loci for conformation and functional traits in Canadian Holstein bulls.
Genetic improvement of livestock populations can be achieved through detection and mapping of genetic markers linked to quantitative trait loci (QTL). With the completion of the bovine genome sequence assembly, single nucleotide polymorphism (SNP) assays spanning the whole bovine genome and research work on large-scale identification, validation, and analysis of genotypic variation in cattle ha...
