Week ending farm notes 18-03-19

Cows are now at full rate zinc in dosatron as we see the pasture burn off and a likely reduction in grazing residuals in the near future. Spore counts today were between 5 and 15k, our first hint of activity in the paddocks.  We will now conduct faecal samples and be ready to trigger to boluses if required.
