  • NIWA’s climate outlook predicts a warm, wet winter for the upper North Island. Climate predictions are increasingly accurate so it’s appropriate to prepare for wet conditions. For some areas it’s already too wet. Successful wintering means arriving at calving with pastures in a good state to re-grow, with little pugging, and maximising the area of the farm at the correct length to encourage growth (i.e. average farm cover no more than 2400, or no less than 2200 kg DM/ha). Current high covers and growth rates might tempt you to abandon long rotations to reduce pugging damage, but speeding up the rotation can result in cows underfed in early spring. A trial in the 1980’s at Ruakura No.2 Dairy demonstrated this. Herds on a fast rotation before calving had less feed at calving and slower growth rates in early spring compared with herds on a slower rotation before calving. Pugging must be avoided, but not by going faster. If you speed up the rotation, then slow down during fine periods to keep farm cover. Increase the level of supplement during fine periods if necessary. Avoid grazing pastures too frequently. Is the stand –off area ready for the likely wet winter?
