Weekly Summary 14 February 2025

Introduction

  • Latest pasture quality results: Crude protein ranged from 17.1 to 25.4% helping explain the swings in milk urea nitrogen we are seeing the vats; NDF from 44.1 to 51.8%, metabolisable energy from 10.8 to 12 MJME/kg DM and soluble sugars from 1.9 to 9.4.

  • We are continuing to graze new grass paddocks, which will offer as a full feed between am and pm milkings rather than 1-2 hours immediately before the pm milking to get them grazed off faster. 

  • We're putting them onto paddocks full to reduce the risk of nitrate issues but given current in-shed feed allocations cows will not be going back to the paddocks hungry.

  • Targeting effluent applications on new grass and baleage paddocks. 

  • SCC creeping up so did a full strip of all cows to identify clinical and subclinical mastitis for treatment. Herd test next week will be used to identify staph cows and do Johnes screening. 

  • Maintenance fertiliser applications to start next week, N applications will be dependent on rain in the forecast. 

  • Second scan scheduled for 5th March, heifers being scanned Friday. 

  • Revisiting culling decision criteria and timing. 

Our research is looking at comparisons between a 'Standard' herd (average BW Southland herd stocked at 3.2 cows per ha wintered on swedes) and a 'Future' herd (higher genetic merit cows (127 BW difference) with a lower stocking rate (2.5), less imported lactation supplement, wintered on baleage).

The Standard herd

  • Will reduce baleage and PKE allocations as cows graze through new grass paddocks.

  • Rotation out to 27 days and will lengthen further with more new grass paddocks coming in.

  • Monitoring FEI with increased intake of PKE.


The Future herd

  • Winter italian paddocks to be harvested for baleage this week.

  • Rotation out to 30 days will one new grass paddock still to be grazed.
