Figure 7 - Grazing methods. Dotted lines refer to uninterrupted transferable fences with the exception of “Creep grazing”, where fences include selective gates (from Molle et al., 2004). 112
How should the number of paddocks be calculated? Rotational, strip and leaders-followers grazing methods require that the number (N) and the dimension (H, in ha) of each sector of pasture be assessed. For a given sward canopy, it is necessary to know (Brandano and Rossi, 1975): 1. the optimum range of sward height to start grazing (usually, 5-10 cm); 2. the occupancy period of a sector (O). This is the maximum number of days the animals remain in a given sector to avoid them grazing the re-growing grasses (usually, 4-8 days); 3. the stay period of a sector (S). This is the number of days a group of animals (lactating ewes, dry ewes, replacement maiden ewes, etc.) remains in a given sector (usually it is calculated by dividing the occupancy period by the number of groups G); 4. the rest period (R). This is the minimum number of days that should pass before the same sector is used again (it depends on the season and sward canopy, ranging from 20 days in spring - early summer, to 40 in late summer - autumn). The formula to obtain the number of sectors (N) is: [14] N = (R +O)/S For example, with R = 20 days, O = 4 days and G = 2 (so that S =2), the sectors needed are 12. If one assumes that the pasture has the same productivity, then the dimension of each paddock is easily calculated. Of course the farm itself and the major paddocks have fixed fences, while secondary or mobile fences split up the paddocks into the required sectors, as is shown in Figure 8.
