QTL Experiment in Brief

Animals:

Animals with a daughter desing were selected from 9 Holstein cattle farms in Beijing. In the moderately sized populations for Chinese Holstein, potentially many more daughters were available with multiple records per cow.

Breeds associated:

n/a

Design:

The official Beijing Holstein genetic evaluations are computed twice yearly at the Beijing Dairy Cattle Center. Milk yield, fat yield, protein yield, fat percentage, and protein percentage over 305d are analyzed.

Analysis:

Fourteen microsatellite markers were selected from bovine chromosome 6. Using the marker data and the EBV of the 2,260 cows and their sires, linkage analysis was performed using the regression approach.

Software:

QTL Express Software and CriMap 2.4
