Contenido:

The forage intake in grazing animals has been defined as the product of the bite size and biting rate integrated
within the grazing time. Pasture height and density are the most important factors explaining bite size (Laca and Demment,
1996), while the internal state of the animal, quantity and quality of the available pasture, final products of digestion and
photoperiod have been postulated as the main factors that affect the length of the grazing session (Soca, 2000). Pasture
height and available time for grazing interact with pasture allowance and chemical composition of the supplement, affecting
pasture intake rate, selectivity, energetic costs of harvesting the pasture and the nutritional balance of the animals (Soca,
2000). Experiments, conducted on daily management of a herd of dairy cows, imposed different times of access to grazing
suggest that the control of the grazing time could improve the efficiency of pasture utilization (Soca et al, 1999). This
experiment was carried out to evaluate the effect of the control of grazing time and pasture height on grazing behaviour and
the dynamics of defoliation, resulting from growing cattle grazing an improved pasture at the same forage allowance and
supplemented with an energy-rich concentrate.
