Week ending farm notes

 

URL

·        Cover has decreased this week to 2255kgDM/ha with the whole farm growing 57kgDM/ha/day.  Cows have grazed 5.6ha/day this is equivalent to a 27 day round of the whole farm or 23day round of the paddocks held in the grazing round for the last week (127 ha).  11ha were excluded from the wedge for silage, but in the coming week will be grazed off.

·       Cows appear to have been allocated 17.5kg of pasture this week, and on most days have sought any shade available in the heat of the day reducing the amount of time spent grazing.  Milkers have been producing an average of 1.59 kgMS/cow this week ranging from 1.66kg/cow to 1.54kg/cow.  The week ahead will see allocations lifted slightly with the long grass ahead, and introduction of PKE when it fits from Friday onwards at 1kg/cow.

·        With a rapidly drying farm, cows have grazed to just under 1500kgDM/ha twice this week, and closer to 1600kgDM/ha several times as well.  The nature of grass at the moment means accurately predicting the cover is proving a challenge.  As such the decision to eat off our previous surplus is an easy one to make.  Holding the slowest possible round right now is vital to maximise growth.

·        The feed wedge surplus at the top of the wedge is to be eaten in the coming week, and will stretch our round out to 33 days of the area in grass on farm, with all grass paddocks in rotation.  This should create a nice breathing space for the other paddocks on the farm to grow quietly in the current weather.

·        Soil temp has lifted rapidly this week, and considerable areas of the farm are burning off in pasture.  See images attached.
