The work was carried out to evaluate the to growth in kg and in relation to live weight (% LW) and to empty body weight (% EBW) of the viscera and other corporal components with increase of the age of Holstein male calves. Eighteen animals distributed in three slaughter age (six at birth, six at 50 days and six at 110 days of age), weighing between 30 and 100 kg LW or 27.57 and 74.27 kg EBW were slaughtered. After the slaughter, the viscera and corporal components were retired and heavy. Data were submitted to a correlation and regression analyses. An increment of absolute weight was observed of the viscera and other components of the live weight in agreement with the increase of LW and EBW, in intense way to the 50 days and moderated of the 50 to the 110 days of age. However, there was a decreased of the relative weight (% LW and % EBW) in accordance that the animals grew, for the stomach, intestines and content gastrintestinal relative weight that stayed growing until the 110 days of age.
