  • This autumn appears to be an opportunity to “nail” the pasture cover and BCS targets for the start of winter and then calving, and produce some milk at low cost at the same time by reducing or eliminating nitrogen fertiliser and supplements

    Discussion about coping with the rare event of surplus grass in autumn includes whether to carry the higher pasture cover forward into winter as pasture, or make autumn silage.

    Experience tells us that autumn silage is not a great idea. It adds some cost and wastage. Those that have tried it usually report that the quality is low and the paddock recovery delays the return to the rotation and risks a hole in the feed wedge later in the autumn. 

    The preference is that the higher covers are carried forward into late autumn and winter. Risks include having parts of the farm getting long and reduced future pasture growth rates. Attempt to achieve tidy consistent grazing residuals of 1500-1600 kg DM/ha, although the consequences from missing this in autumn are not as great as in spring. Additionally most herds will soon have dry cows based on their low BCS and early calving date, and they can be useful to lower the grazing residual on parts of the farm.
