Grass Watch Report – June 2016

Grass Watch report for 3rd June 2016

Grass Watch Logo


Grass growth has started to slow, falling 21kg DM/ha/day to an average of 79kg DM/ha/day.

Declining growth rates will mean that it will be important to monitor grass supply closely to ensure potential shortfalls are identified as early as possible as the summer progresses.

We are fast approaching the summer solstice and daylight hours are still increasing leading to an increase in the potential grazing hours available.

Predicted grass DMI has risen by 1.8kg DM/day to 13.5kg DM.

This has underpinned an increase in the potential milk yield from grazing, from M+ 10.8 litres/day last week to M+ 14.9 litres/day this week. This is driven by grass availability and grazing hours in daylight as grass quality is lower than the seasons average with ME at only 11.4 MJ/kgDM.

The higher NDF content and NutriOpt Fibre Index will help support butterfat.

The average crude protein content of the grass samples sent into the Trouw Nutrition GB lab has fallen slightly from last week to 20.77%, which is close to the 6 year average of 20.94% for this time of year.
