HubWatch - 17 September 2026

Your weekly glimpse into research in action at Southern Dairy Hub.

Insights

  • Standard herd: The herd was split late last week. There are currently 202 mixed-age cows in the Std 1 mob and 226 R2s, R3s and approximately 30 lighter mixed-age cows in the Std 2 mob.

  • High pre-graze covers at the top of the feed wedges, along with silage and in-shed feeding, are allowing us to maintain the spring rotation plan area allocations for both farmlets. With ground conditions impacting silage utilisation, we are opting for more in-shed feeding for the Standard herd to capitalise on the better utilisation of this feed.

  • Nitrogen applications are becoming a little more urgent if we are to avoid a pasture deficit in the second round. However, with soils still at field capacity and paddock conditions too wet for vehicle application, we will continue to hold off until conditions enable a good response to the nitrogen and sulphur applied.

  • We are working through strategies to prepare for the forecast El Niño. Early conversations with contractors to maximise the chances of good crop establishment, using N for the best response, and discussing options for calves to go off earlier to generate more baleage from the support block are all in the mix.

  • The effluent pond is now at 80% capacity, so we are hoping for some settled weather soon so we can start applying.

  • All cows that have been calved for more than two weeks will be Metrichecked this week.

  • The first calves ventured outside this week.

Farm System Description
