Preparing for autumn grazing
Rotation length should increase from 25 days in mid-August to 35 days by mid-September and 45 days by the start of the last rotation.
Grass covers should increase to a peak of 450 kgDM/cow or 1,150 kgDM/Ha in mid- to late-September. 
Do not build up too much grass as heavy covers are difficult to graze under wet conditions and will delay the achievement of the 60% target.
Assess grass covers in early September.  Blanket spread the entire farm with 30 /Ha N before September 15th where possible. 
Use KOCH KAN instead of CAN
Get P & K out where required
Autumn grazing - objectives
Keep grass in the milking cows’ diet for as long as possible this autumn.
Allocate a portion of the farm for grazing each day.
Start closing paddocks from the 10th October onwards (1-2 weeks earlier in wet areas).
Aim to have 60% farm closed by the end of the first week of November (1-2 weeks earlier in wet areas).
Leave the grazing platform with an “adequate grass cover” when the cows are housed.
The target closing cover is 220 kg DM per cow or 560 kg DM per ha
Key Message: The key to providing grass for your milking herd next spring is to graze 60% of your grazing platform by end of the first week of November.  The paddocks grazed by this date will have an opportunity to grow grass before growth rates decline in November.
Autumn grazing - guidelines
Graze paddocks to 3.5 - 4 cm to encourage winter tillering of the grass plant.
From the 10th of October do not re-graze fields that have been closed.
Feed supplements if there is insufficient grass in the daily allocation.
Skip heavier paddocks – and graze paddocks with ideal covers - to meet 60% target if necessary.
Use wet weather grazing techniques if ground conditions deteriorate.
Key Message: During the last rotation, you must focus on grazing residuals if you want to have top quality swards for your milking herd next spring.
Poaching management:
Good roadways, multiple access points and numerous watering points are a must
During wet weather on / off grazing must be utilised to prevent grass soiling and soil damage
In larger paddocks back fencing is required to prevent poaching after grazing off

Calculations

Calculate Stocking Rate: Divide the number of cows by the area available for grazing (hectares).

For example, 60 cows ÷ 24 hectares = 2.5 cows/ha

Calculate Cover per Cow: Divide average farm cover by stocking rate.

For example, 1,130 kgDM/Ha ÷ 2.5 cows/ha = 450 kgDM/cow

Calculate Allocation per Cow: Divide grass available on paddock by number of cows.

For example, a 2.5 hectare paddock with a cover of 1,500 kgDM/Ha has a total cover of 2.5 x 1,500 = 3,000 kgDM.  If there are 60 cows grazing this paddock, then there is an allocation of 3,000 ÷ 60 = 50 kgDM/cow (three days full-time grazing at this time of the year).
