The objective was to evaluate the processing of the grain of millet in supplements given daily or three times a week to grazing beef cattle on productive performance, economic and diurnal intake behavior during the drought period. Twenty-five non-castrated Nelore cattle with initial body weight of 350.92±31.7 kg were kept in five paddocks with unit area of 1.45 ha formed by B. brizantha cv. Marandu. The animals were distributed in a completely radomized design in a 2 × 2 + 1 factorial arrangement, as follows: two physical forms of the grain of millet (whole or ground), two frequencies of supplementation (daily or three times a week) and the control treatment (mineral mix). It was found that the concentrate supplementation promoted weight gains, while sole mineral supplementation resulted in weight loss of 0.16 kg/animal/day. Grinding the millet grain promoted higher gains (0.36 and 0.38 kg/animal/day for 3 and 7 times a week, respectively) when compared with the whole grain (0.22 and 0.24 kg/animal/day for 3 and 7 times a week, respectively), with no differences between the frequencies of supplementation. Significant effect of the day × treatment interaction was found for time in the trough, grazing and drinking water. For the resting time difference was found between the control treatment and the others. Greater economic return was achieved when ground millet was supplied at lower supplementation frequency (R$ 22,70/animal). The use of multiple supplements, as well as the processing of millet grain, enabled greater weight gain, regardless of the supplementation frequency studied. Providing supplement 3 times a week reduces the costs with supplementation.
