Week ending farm notes

February 2018

·        Cover has increased this week to 2494kgDM/ha with the whole farm growing 46kgDM/ha/day.  With 39mm of rain received in the week

·       Cows have grazed 3.3ha/day this is equivalent to a 44 day round of the whole farm or 35 day round of the paddocks held in the grazing  round for the last week (115 ha). 

·       Milkers have produced an average of 1.13kgMS/cow, having now curved around a low point and settling around the 1.14kgMS/cow/day.

·       Offering 13kg of grass, has again seen cows leaving above target residual, with un-grazed leaf still evident.  Residuals have ranged between 1525kgDM/ha and 1750kgDM/ha.  This grass left behind offsets some of the discrepancy between supply/demand and change in cover.  THe surplus grass is at the bottom of the wedge in an untidy residual.

·       The feed wedge surplus continues and this week a further 3 paddocks have been excluded now – a total of 27ha out for silage. We are actively working to keep cow’s pre-grazing covers in leafy pasture of no more than 3,000kgDM/ha, but struggling to speed up the round as we would wish to.  As we approach the silage cutting date we may look to throw other paddocks out for silage too – right now we have approximately 20% of the grass area out of round.  This pushes our demand on the remaining 110ha grass platform 49kgDM/day and we should be in balance on this area moving forward.

·       Spore counts returned a result between 0 and 40,000 on Friday and between 0-25,000 today. Zinc continues in the Dosatron, but with increasing counts boluses are still a very real possibility.
