Quantitative trait Loci for health traits in Finnish Ayrshire cattle.
A whole-genome scan was conducted to search for quantitative trait loci (QTL) affecting health traits in Finnish Ayrshire dairy cattle. The mapping population consisted of 12 bulls and their 491 sons in a granddaughter design. A total of 150 markers were typed covering all 29 autosomes. The traits under study were somatic cell score, mastitis, and a group of other veterinary treatments. Effects...
متن کاملQuantitative trait loci affecting milk production traits in Finnish Ayrshire dairy cattle.
A whole genome scan of Finnish Ayrshire was conducted to map quantitative trait loci (QTL) affecting milk production. The analysis included 12 half-sib families containing a total of 494 bulls in a granddaughter design. The families were genotyped with 150 markers to construct a 2764 cM (Haldane) male linkage map. In this study interval mapping with multiple-marker regression approach was exten...
متن کاملA search for quantitative trait loci for milk production traits on chromosome 6 in Finnish Ayrshire cattle.
Cattle chromosome 6 was scanned with 11 markers, ten microsatellites and the casein haplotype, to identify quantitative trait loci (QTLs) affecting the following milk production traits: milk yield, fat percentage, fat yield, protein percentage and protein yield. Twelve Finnish Ayrshire half-sib families with a total of 480 sons were genotyped and used in a grand-daughter design. Interval mappin...
متن کاملInternational Genetic Evaluations for Udder Health Traits in Dairy Cattle
Mark, T. 2005. International Genetic Evaluations for Udder Health Traits in Dairy Cattle. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-6992-9 The aim of this thesis was to investigate different approaches for international genetic evaluations of dairy sires for udder health traits. For this purpose, deregressed national genetic evaluations were used of Holstein milk somatic cell (SC) from...
متن کاملWhole genome scan to detect quantitative trait loci for conformation and functional traits in dairy cattle.
A granddaughter design was used to locate quantitative trait loci determining conformation and functional traits in dairy cattle. In this granddaughter design, consisting of 20 Holstein Friesian grandsires and 833 sons, genotypes were determined for 277 microsatellite markers covering the whole genome. Breeding values for 27 traits, regarding conformation (18), fertility (2), birth (4), workabi...
