This is a summary of the key lessons learnt from the 3 year Dairying in a Variable Climate trial looking at production and profit responses to adding PKE and other supplements. For more detailed information see the annual summaries at the end of each season. 3 yr Summary – Lessons […]
There have been many studies looking at the effects of teat spraying (TS) and dry cow therapy (DCT) as single treatments. This 2011 trial was unique in the way it measured how a combination of teat-spraying and whole herd DCT affect clinical mastitis and production in a pasture-based herd. […]
This plot trial in spring 2019 looked at pasture responses to Nitrogen, Sulphur and Potash. The trial was driven by farmers asking whether it was economic to apply Ammo or Potash instead of straight urea in spring. Three sites were used to test responses on different soil types Marine Clay […]
Supplement Use in a Variable Climate Trial results are in for the 2019/20 season. The effect of the drought is clear with all farms dropping in profit by $600 to $1200/ha. The PKE Plus farm was the most profitable for the first time in this trial, but needed the high […]
This trial at NARF compared a kikuyu based farmlet with a ryegrass farmlet for profitability under best practice. The kikuyu was mulched and undersown with Italian rye in autumn, effectively transitioning the pasture to ryegrass each spring. Supplements were fed in order to maximise profit on both farmlets.
