O presente estudo foi desenvolvido com o objetivo de quantificar as variações das vísceras e demais componentes corporais, de forma absoluta e relativa com base no peso vivo (PV) e peso de corpo vazio (PCVZ), em função da idade de bezerros machos Holandês. Foram abatidos 18 animais, distribuídos em três idades de abate (seis ao nascimento, seis aos 50 dias e seis aos 110 dias de vida), apresentando entre 30 e 100 kg de PV ou 27,57 e 74,27 kg de PCVZ. Após o abate, as vísceras e componentes corporais foram retirados e pesados. Os dados foram submetidos a análises de correlação e regressão. Foi observado incremento de peso absoluto das vísceras e demais componentes do PV, de acordo com o aumento de PV e PCVZ, de maneira intensa até os 50 dias e moderada dos 50 aos 110 dias de vida. No entanto, houve decréscimo do peso relativo (% PV e % PCVZ), à medida que os animais se desenvolveram, com exceção do peso relativo de estômago, intestinos e conteúdo gastrintestinal, que se manteve crescente até os 110 dias de vida. 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
