Ultrasonic assessment of meat quality traits in pigs

Meat quality indicators were studied in Large White pigs using an ultrasound real-time AQUI-LAVET PRO system. A slide-format passport specifying the fat-deposition and muscle-development topography was provided for each animal selected for a replacement stock. The lean meat yield (57.8) was associated more with a section of longissimus dorsi ( r = 0.85) than with a value of backfat thickness ( r = − 0.66). Equations and coefficients were estimated for a “daughter-mother” rectilinear regression to obtain age indicators for reaching a 100-kg weight and some backfat thickness.
