“…These involve identification of animal species in ground meat mixtures (Winquist et al, 1993) or fat tissue (Beattie et al, 2007) LD -longissimus dorsi; TB -triceps brachii; R 2 -coefficient of determination; r -correlation coefficient; P -prediction; C -classification; VIS -visible; NIR -near infrared; IR -infrared. (Hwang et al, 1997), detection of RN -phenotype in pigs (Josell et al, 2000), the "walk-through" weighing of pigs (Wang et al, 2008), the efficiency of ANN for visual guidance of pig evisceration at the slaughter line (Christensen et al, 1996) and the use of ANN for the processing control of meat products (Eklöv et al, 1998;Ibarra et al, 2000;Santos et al, 2004). Again, in the majority of studies, ANN approach was an instrument to deal with the complex output signal of novel technologies applied.…”
