Effect of genotype, sex and slaughter weight on veal Longissimus muscle area measured by ultrasound and planimeter

The aim of this research was to determine effect of genotype (Holstein, Simmental and their crossbreeds), sex and slaughter weight groups (SW1= 150-160 kg and SW2=190-200 kg) on veal longissimus muscle area (LMA). Between the12th and the13th rib, two ultrasound LMA (ULMA) images were taken from each animal and carcass LMA (CLMA) traced on transparent foil was measured by planimeter. For both measures, Simmental calves had larger LMA than Holstein (P
