March 26

 

·        Cover has dropped slightly this week to 2044kgDM/ha with the whole farm growing 34kgDM/ha/day.   The range in growth of paddocks is a  meagre 8kg/day up to a maximum of 62kg/day.  25mm of rain over the weekend was incredibly welcome and the average growth seen for the week has increased since Saturday, with pastures looking much healthier than they did a week ago.

·        Cows have grazed 4ha/day, this is equivalent to a 37 day round of the whole farm or 32 day round of the paddocks held in the grazing round for the last week (127 ha).  3 paddocks have now been sprayed out to sow into annuals ahead of next year’s Summer Turnips another 5.2ha out of rotation, but the first paddock of regrassing is back in.  The net result is that we have 123ha in the grass rotation for the coming week.

·        Milkers have produced an average of 1.15kgMS/cow, with a diet of 4kgPKE (3.6kgDM), 4kg grass silage and 9.5 kg grass offered during the week.  With slow growth and a few pre-grazings below anticipated levels, pasture allocation to cows decreased below anticipated levels.   32 culls go today and their total daily allocation - 32 cows x 17.1kgDM/cow = 547kgDM freed up to distribute to remaining cows on hand (380), or an extra 1.4kgDM/day to every cow left on the farm.  A further 20 cows will be removed ASAP based on available works space, which will offer further feed allowance benefits.

·        Priority feeding remains to the at-risk cows based on BCS, and approximately 60 will be dried off in one week’s tome after the last herd test.  Followed by another 80 10 days later and another 80 around ANZAC day.

·        Eczema spore counts remain at 25,000.  We continue to monitor at this stage and will conduct another round of Faecal zinc levels and faecal spore counts ASAP.
