Evaluates how different forage NDF levels affect growth performance and intake in Nellore bulls, suggesting diet modifications may not sustain benefits long-term.

Key Points

The study investigates the impact of fixed and changing forage NDF levels on the intake and growth performance of Nellore bulls.
56 Nellore bulls were fed varying forage NDF levels over 100 days
Diets of 12% and 7% NDF were tested across two periods
Data on growth performance, intake, and carcass traits were collected and analyzed.
Bulls on 12% NDF had significantly higher average daily gain (ADG) and dry matter intake (DMI) during the first 50 days
Switching NDF levels showed no significant differences in growth performance after 100 days
Overall benefits of 12% NDF did not persist throughout the trial.
