Note: The rotation length at the start of calving is normally 100 days. Lower stocked farms may start at 80 days.
Note:The rotation length at balance date is usually 20-25 days. Lower stocked farms or farms with using high amounts of supplements may go to an 18 day round. Farms that are subject to very volatile growth rates (one week 80 kg DM/ha the next week 20 kg DM/ha) tend to have a slower rotation (23-25 days) at balance date as do high stocked farms.
Note: The opening cover should be the target cover required at calving not the actual cover at calving.
