Average GB grass growth rates have continued to decline this week to 52 kg DM/ha/day, down from 55 kg DM/ha/day last week. The potential grass DM intake has also fallen to 6.6 kg/day. This is down 1.3 kg/day in comparison to last week. The continued decrease in potential grass DM intake and a slight reduction in average grass ME has put further pressure on milk yield from grazing, with the current average at -1.3 litres/day. However it is important to note there is a range in the data from -9.9 litres/day to 9.1 litres/day.
With wide variations in the potential milk yield from grazing across farms there must be continued attention on buffer feeding to avoid excessive body condition loss, which can be costly in terms of lost milk production through the first months of winter.
