Virtual dissection of lamb carcasses using computer tomography (CT) and its correlation to manual dissection

摘要: Hundred and nineteen lambs from a single abattoir in Norway were scanned using computer tomography (CT) at different equidistances (40, 80, 160 320 mm) to perform virtual dissection of the carcasses, separating muscle, fat bone tissue. The population sheep used covered commercial range breeds body composition full conformation scores. After CT scanning, carcasses manually dissected by trained butchers. volume weight all estimated Cavalieri estimation slices. precision reliability repeated measurements splitting into two halves. results showed that (r > 0.95) was more precise reliable than manual 0.80), both for carcass tissue weights proportions. correlation between high muscle weight, however, lower tissues. dissection, highest low equidistance scanning (40 mm). There some biases especially source bias can be explained inaccurate performed butchers underestimation estimation.
