Resumo: | This study aimed to evaluate four deferral periods for pastures of Brachiaria decumbens cv. Basilisk, and the implications on the ingestive behavior of crossbred heifers. Animals were distributed in a completely randomized design with four periods (63, 84, 105 and 126 days), each with three replications. The time spent daily by animals on grazing, idle, rumination and in the trough was not affected by periods of sealing the pastures, with mean values of 566.6; 422.29; 426.9 and 24.1 minutes, respectively. The number of feeding stations, the time spent in the stations and the number of feeding stations per minute were not different between periods of sealing the pastures, averaging 106.4; 34.6 and 3.0, respectively. The number of bites and the number of bites per minute showed a quadratic effect, with a point of maximum equal to 1,098 bites and 31 bites per minute, observed on days 93 and 88, respectively. Feed efficiency was linearly decreasing influenced by periods of sealing the pastures. Periods of grazing and idle, the number of bites, the number of bites per minute and feed efficiency are influenced by different deferral periods of pastures under the conditions of this study. |

Basilisk, e suas implicações sobre o comportamento ingestivo de novilhas mestiças. As novilhas foram distribuídas em delineamento inteiramente casualizado, com quatro períodos (63, 84, 105 e 126 dias), cada um com três repetições. Os tempos gastos diariamente pelos animais em pastejo, ócio, ruminação e no cocho não foram influenciados pelos períodos de vedação dos pastos, com valores médios de 566,56; 422,29; 426,98 e 24 minutos, respectivamente. O número de estações alimentares, o tempo nas estações e o número de estações alimentares por minuto não diferiram entre os períodos de vedação dos pastos, com médias de 106,37; 34,65 e 3,04, respectivamente. O número de bocados e o número de bocados por minuto apresentou efeito quadrático, com ponto de máxima igual a 1.098 bocados e 31 bocados por minuto, alcançados aos 93 e 88 dias, respectivamente. A eficiência alimentar foi influenciada de forma linear decrescente pelos períodos vedação. Os períodos de pastejo e de ócio, o número de bocados e número de bocados por minuto e a eficiência alimentar são influenciados pelos diferentes períodos de diferimento dos pastos, nas condições de realização desta pesquisa.
