Twelve microsatellite markers on chromosome 6 were analyzed in German Holstein population to detect and locate QTL affecting daily body weight gain (DBWG). The results indicate promising location for QTL controlling daily body weight gain trait on chromosome 6. Where, three markers BMS2508 BM3026 and TGLA37 at three different positions in a distance 15.2 cM on BTA6 were associated with significant effects for daily body weight gain trait (DBWG). Comparison between this finding and previously identified QTL support the location of a QTL for growth traits on chromosome 6, where a significant QTL for birth and yearling weight was previously identified on chromosome 6 tightly close to marker BM3026. Finding from this study could be used in subsequent fine-mapping work and applied to marker-assisted selection (MAS) of production traits.
