March 2018

·        Cover has held this week at 2102kgDM/ha with the whole farm growing 51kgDM/ha/day.

·        Cows have grazed 4.8ha/day, this is equivalent to a 31 day round of the whole farm or 28 day round of the paddocks held in the grazing  round for the last week (137 ha). 

·       Milkers have produced an average of 1.21kgMS/cow with cooler weather, and shorter pre-grazing covers and a diet of 15kg grass plus 2kgPKE offered. Pasture samples have seen about a 1.0MJME/kgDM lift in quality, and a 2-4% lift in soluble sugar content.  It seems the grass is enjoying some cooler weather also.

·        Residuals have been far better this week also with cows happily grazing to 1500-1550 in most paddocks.

·        The wedge still shows a deficit coming as the silage paddocks lag a little in re-growth still. In addition we have advanced the spray out of our 8ha for grass-grass regrassing by 10 days as they were grazed this week. This gives us an effective grazing platform of 129ha for the week ahead.

·        We will fill the looming deficit with supplements, at first this will be an increase of PKE over the next three weeks to test our FEI at both 3kg and 4kg/cow/day.  Should growth still be less than demand we will start our silage feeding as required.

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