Abstract

The effect of restricted or ad libitum supplementation on finished beef cattle on pasture during the dry season is provided. Forty-eight animals were divided into two groups, each receiving feed in two modalities: restricted or ad libitum feeding, in a randomized design, with twelve replications. Supplementation with restricted feeding afforded a weight gain of 0.597 kg, whereas ad libitum feeding yielded 0.613 kg of weight gain. There was no difference (p > 0.05) in live weight gain during the first period (0.878 kg and 0.922 kg). Differences occurred in the second (0.586 kg and 0.383 kg) and third (0.282 kg and 0.578 kg) periods studied in the case of restricted and ad libitum feeding respectively. It may be concluded that ad libitum supplementation was a disadvantage.
