Week ending farm notes

 

We were very lucky to get 5.8mm of rain overnight. It was very welcome - unfortunately sounds like the distribution of that benefit around the rural areas been quite varied.
As mentioned yesterday the cows were sent back for re-grazing overnight and tidied grass up a lot better in the few paddocks where residuals had crept up. 
We've also had a challenge put to us by a trusted advisor to have a good think about our current position and to react more to where our feed is right now, than worrying 3 months ahead.  Quite fair! 
So, we will drop our PKE usage back to 1kg/cow/day for the next 2 weeks while we still enjoy this growth ahead of us but allocate no more pasture/day - instead force higher utilisation on the herd.
We're going to keep farm walking each week through the holidays, so we can still react to any changes in cover quickly.
