Heavy rain across the country over the last few days has seen ground conditions deteriorate in many areas and the forecast for the coming week shows little sign of improvement. During periods of constant rain, grass dry matter (DM) becomes significantly lower – anywhere between 10% – 12% DM. For comparison sake, during a week of dry weather, grass would normally be 18% – 20%DM.

This means in every bite of grass a cow takes during periods of wet weather, they are taking in over 40% less dry matter than in normal conditions.
