Week ending farm notes
- Cover has climbed this week to 2167kgDM/ha with growth settling around 68kgDM/ha/day and includes the impact of calves (“the nibblers”) eating feed out of the middle of the wedge.
- The herds grazed 6.17ha/day equivalent to a 24 day round of the whole farm or 22 days of the 136ha in grass with 11ha out in cropping area.
- Cows have dropped again this week, to 1.87kgMS average for the week, and as outlined in yesterday’s information this is largely a reflection of changing quality in the grass plants. This is reducing time taken to digest food and therefore has reduced intake. We have now reduced allowances, this week by reducing area offered to ensure satisfactory residuals – cows grazing to 1500-1600, tops out of most clumps
- Residuals for milkers have averaged close to 1,550kgDM/ha with a few “send backs” to tidy up some residuals. Overall we have seen cows doing a good job, but most paddocks have some stem and seed left behind that we will deal with mechanically.
- Roughly a third of the paddocks this week were mowed ahead of the cows as we get into reducing the effort for cows to harvest their food in an environment where the plant is being somewhat unco-operative.
- Key management decisions.
- Grass is doing what we saw in Dec-Feb last year, burning out sugar into NDF. We know the longer the grass gets the worse this impact.
- We are going to keep pre-grazing levels for the herd under 2800kgDM/ha as well as pre-mowing.
- We want to stay on our faster rounds, and not slow down chasing the longer covers.
- We will drop out surplus again now to address the excess growth in the wedge.
- We are forecasting growth over the next two weeks at 65kg/ha/day
- We will make a light quick silage cut to get back in the round and stacked within 10 days from now.
- With demand of approximately 60kg/day including calves and growth of 65kg likely ahead of us we are growing 8% more than demand each day. Removing 8% of the paddock will settle our supply demand imbalance. We have 9ha from the top of the wedge allocated to head into the stack middle of next week
- Evaluation of crops shows the same nasty little insets in the younger crops and they will be sprayed to address this.
- With 46 days of AB completed we have put 99% of the herd up to date – 4 cows have yet to cycle, all calved around September 1st.
- Feeding levels this past week have been as follows,
- Calved cows 19.5kg grass offered
- Feeding levels for the coming week are planned as follows,
- Calved cows 19.5kg grass offered.
Challenging times – but we’re happy with our plan to try and protect the cows production over the next 3 months.
