Cover has held this week at 2065kgDM/ha with the whole farm growing 35kgDM/ha/day.
Cows have grazed 4.2ha/day, this is equivalent to a 35 day round of the whole farm or 30 day round of the paddocks held in the grazing round for the last week (127 ha).
Milkers have produced an average of 1.19kgMS/cow, with a diet of 4kgPKE (3.6kgDM), 4kg grass silage and 10 kg grass offered during the week.
Growth has stalled further despite warm soil temperatures. However high ambient temperatures and dry ground underfoot is seeing areas burn off as if under moisture stress.
We will maintain our current levels of supplement and look to exit cull cows as soon as possible to ease demand, and deploy feed resources to the cows we are calving next spring.
Eczema spore counts remain at 25,000. We continue to monitor at this stage.
