title: [Study of mapping QTLs for milk traits on the German dairy cattle].
abstract: A total of 1,130 bulls belonging to 20 half-sib families of German dairy cattle were genotyped for 229 microsatellite markers on 30 chromosomes. The data were used in an attempt to map quantitative trait loci applying regression as multiple-marker regression. For association analysis with a granddaughter design, the estimated breeding values for 3 milk traits were used: milk production, fat production and protein production. The empirical values of significance thresholds were determined by using a permutation test on the experimental data. Several significant QTLs were found on some chromosomes, especially on the chromosome 14. The results give a strong support for the experiments of Coppieters et al. and Ron et al.
