Grass Watch Report - 9th September 2016

By Steve Brown 3 years ago

For the third week running we have seen an uplift in average grass growth rate to 64 kg DM/ha, an increase of 11 kg DM/ha compared to last week. This is following the expected “autumn flush” with warm and damp weather helping to keep grass growing. We have also seen a drop in grass dry matter, from 16.3% last week to 14.9% in this week’s report. There has also been a slight drop in grass ME, which coupled with a lower potential grass dry matter intake, has caused a drop in potential milk yield from grazing to 6.4 litres, a reduction of 2.6 litres from last week. It is important to ensure that buffer feeding is adjusted to account for this to avoid excessive body condition loss which can be so costly in terms of lost milk production through the first months of winter.

The warm temperatures seen in the past week have meant that the risk of summer heat stress has remained high. With warm and showery weather forecast for the coming week, the risk of heat stress may continue to be high, especially with the high levels of humidity that we can expect.

Continued monitoring of grass growth and quality can help manage day-to-day feed planning on farm and also looking forward to next season, can help ensure winter covers are managed to help maintain grass quality come turn-out in 2017.
