We used 28 cull cows with 68.02±17.36 months of age slaughtered at different weights (461, 476, 434 and 522 kg).
The experimental design was completely randomized with four treatments (slaughter weight) and seven replicates (animals).
The dry matter intake, expressed as kg d-1 and % of body weight, presented quadratic variation with increasing slaughter weight, with the highest values observed for slaughter weight of 461 kg.
