Prediction of carcass energy content of Pelibuey ewes by ultrasound measurements [PDF]
Ecosistemas y Recursos Agropecuarios, 2017 The aim of this study was to evaluate the relationship between body ultrasound measurements (USM) and carcass energy content (CEC) of Pelibuey ewes. USM were taken 24 h before slaughter in twenty-two ewes. Fat thickness (FT) and Longissimus dorsi area (LDA) were determined in the thoracic (TFT and TLDA) and lumbar region (LFT and LLDA).
