Step 1. Estimate The Forage Demand:
8
9
The forage demand is the amount of forage dry matter (DM) required to feed the herd/flock for one day.
10
It is calculated based on the rule of thumb that grazing animals need to have daily access to approximately 4%
11
of their live weight in forage (2.5% intake, 0.5% trampling loss, 1% buffer). This figure may be adjusted
12
depending on specific animal needs or pasture management techniques or if you are willing to supplement
13
hay or grain during periods of low production.

Step 2. Estimate the Forage Supply:
36
37
This is the amount of forage dry matter that is predicted to be available for grazing after a 15 day growth period in the
38
spring and a 30 day growth period in the summer and fall. Actual pasture growth rates are extremely variable.
39
As a result the numbers presented are for planning purposes only. Optimum growth rates may be longer or shorter
40
than those indicated.
41
42
Unless actual measured yields are available, use estimated yields such as NRCS Soils 5 data for grass-legume hay or
43
UWEX figures. Use the following table to convert to forage availability on a rotational basis, average over five to
44
six rotations.

Step 3. Select Residency Period:
58
59
In other words, decide how long you want your livestock to remain in a particular paddock. One to two days is recommended
60
for lactating dairy cows, dairy sheep, goats and growing steers; three to seven days for all other livestock. For maximizing
61
harvest efficiency, use the shortest residency period indicated for the type of operation.
62
63
Residency Period=1.0days
64
65
Step 4. Determine Paddock Size:
66
67
The paddock size is based on meeting the total forage demand for the number of days of grazing indicated by the residency period.

Step 5. Calculate the Number of Paddocks:

The number of paddocks required is based on meeting the longest regrowth interval recommended, i.e. 30 days.
