The intensity of MLLT area changes and development of chosen body parts muscling in bulls and heifers of Blonde d´Aquitaine cattle during rearing period

Original language description

The objective of this work was to determine effect of animal sex, breed and birth season of calves to intensity of MLLT area changes and development of chosen body parts in bulls and heifers of Blonde d´Aquitaine (BA) cattle during rearing period. Two generations of bulls (n=63) and heifers (n=68) of Blonde d´Aquitaine (n=61) and crossbreds CxBA (C ? Czech Pied Cattle) (n=70) born from December 2004 to June 2006 were evaluated. MLLT area measurements and subjective evaluations of 3 basic body areas muscling (shoulder, back, rump) on live animals were performed at 120, 210 and 365 days of animal age. Statistically significant differences were determined in shoulder, back, and rump muscling in relation to animal sex in favor of bulls at 120 and 210 daysof age (P < 0.01 to P < 0.001). Purebred animals achieved significantly higher muscling of rump at 120 days, and muscling of rump and back at 210 days (P < 0.05 to P < 0.001). Statistically significant differences were determined in anima
