Week ending 20-1-20 farm notes:
With only 5.6mm of rain since the rainfall event on the 20th Dec we are feeling fairly crisp at the farm. APC has dropped to 1897 kgDM/ha with a low growth rate of 15kgDM/ha/day.
The 3 in 2 milking routine and feed allocation has become a fairly easy routine now. Everyone is enjoying being away from the shed during the hottest parts of the day. This combined with sprinklers on the yard, access to shade during the day, and access to water troughs in the races has helped alleviate the stress of the hot week we have had.
We have recorded daily highs of around 24-29◦C and around 11-15◦C at night. This is well over the comfort zone for a cow at 4-20◦C.
Feeding for the last week has been approx. 6kgDM grass, 5kgDM grass silage, 4kgDM crop and 2kgDM PKE total of 17kgDM allocated.
This week we will be starting to feed our one paddock of deferred grazing. We are planning to offer the big herd of 240 cows 2.5kgDM per day (based on a 1800kgDM residual), 5kg grass silage, 4kg crop and 2kg PKE up to 4.5kg pasture = 18kgDM.
The smaller herd will receive the same total but with 7kgDM pasture. The feed wedge is looking tight this week but we will maintain a 37 day round and the cows will receive whatever pasture is available in that area allocation with the aim to feed between 16-18kgDM total diet.
We have had 6 cull cows leave the farm and another 30 are booked for early and mid-Feb. We still have 3 weeks of turnip crop and another 2 weeks of kale crop based on current feeding levels.
We will hold the current feeding and milking system until we carryout PD and BCS.
Time saved in reduced milking is being used by feeding out and shifting cows throughout the day.
On our farm walk we identified 2 paddocks and another 4 paddocks with small patches that have YBG that requires spraying. After close inspection there were only a few seed head. These paddocks will be grazed shortly and then sprayed after grazing with Dockstar.
