Genome-wide association study of mature cow size traits in American Angus cattle.

Highly significant associations were detected on BTA6, BTA7, and BTA20 (e.g., ADG on BTA7, p = 1.16 × 10−58; MBW on BTA20, p = 8.39 × 10−280), with carcass weight QTLs overlapping MWT and BCS on BTA7 ( p = 4.61 × 10−31) and BTA20 ( p = 2.87 × 10−58).
