Genetic parameter estimates of ultrasound-measured longissimus muscle area and 12th rib fat thickness in Brangus cattle.

Journal of animal science - 1 Oct 1993

Johnson M Z, Schalles R R, Dikeman M E, Golden B L

Abstract excerpt

Data from 2,101 Brangus calves born from 1986 to 1990 were analyzed with a REML procedure using a derivative-free algorithm in a mixed linear animal model to obtain variance component estimates of ultrasound-measured longissimus muscle area and fat thickness. Direct additive heritabilities (ha2) of .39 and .40 were obtained for age-constant weaning and yearling longissimus muscle area (WLMA and YLMA,...
