Week ending farm notes

March

·        Cover has dropped this week to 2065kgDM/ha with the whole farm growing 43kgDM/ha/day.

·       Cows have grazed 4.7ha/day, this is equivalent to a 32 day round of the whole farm or 27 day round of the paddocks held in the grazing round for the last week (128 ha). 

·       Milkers have produced an average of 1.19kgMS/cow, whilst the public enjoyed our milking times in the middle of the day on Saturday it has messed with the cows routine.  We’re hoping they will settle back down now.

·       A considerable slowing of growth is not unexpected but we have multiple paddocks in the “stalled growth” category.  This means we will start feeding silage now to ensure we hold our cover as we move into colder months.  This will see 10 days of approximately 4kg of silage, 4kg of PKE and 10kg of grass, whilst the wedge recovers as some of the silage paddocks are lagging.  Then we will reduce to closer to 6kg supplement total fed.

·       Eczema spore counts on Friday last week were between 25,000 and 40,000.  We continue to monitor at this stage.
