To evaluate grazing strategies of cattle on pastures, four Holstein black and white coating heifers were submitted to five sward heights of mombaçagrass (Panicum maximum Jacq.) pasture, in a completely randomized design, with two replications, between February and April, 2002. The experimental animals were evaluated during 45 minutes tests. Number of bites, number of feeding stations, number of steps and feeding time were measured, using chronometers and counters. The number of feeding stations per minute decreased quadratically (Y= 16.3199 – […]
