  • By now, most farms will have passed balance date and pasture growth should be more consistently exceeding stock demand. This will mean that we will be moving into a pasture surplus situation pretty quickly. Surplus management is one of the greatest skills of pasture management and is a critical aspect of maximising pasture eaten and feed quality.

    Grazing residuals drives pasture quality and when growth exceeds demand, residuals will rise unless this surplus is managed. Surplus management is all about anticipation. To get surplus management right requires regular (ideally weekly) pasture assessment to predict feed surpluses before they happen. Identifying pasture surplus early allows better management of a surplus, including decisions around rotation length, removal of supplements and the number of paddocks to shut up.

    Spring grazing management will influence the amount and quality of pasture grown later in the season. Pasture quality is optimised when pastures are grazed between the 2nd and 3rd leaf stages of regrowth, and grazed to residuals of 3.5-4cm (or 7-8 clicks on RPM). By maintaining a strategy of timing grazing pastures between the two and three leaf stages and maintaining more consistent post-grazing residuals, pastures will also persist longer.

    Work hard to achieve a consistent grazing height at each grazing. If you are consistently grazing to below 7-8 clicks, feed the most cost-effective supplement to maintain herd intakes at the required level. If the post grazing residual height is more than 9-10 clicks (1750kg DM), consider using a clean-up mob or top to the lower height after grazing.

    Careful grazing management through the spring will pay dividends in better quality pasture through the period of peak cow production and will identify any feed surpluses as they develop. These surpluses can then be harvested as good quality supplement and the paddocks returned to the grazing round promptly.
