NB: The target lines on these wedges are incorrect. Current area allocation is being determined from the spring rotation planner
Updated APC targets relative to the Spring Rotation Planner
Key Decisions this week
- The milking mob has been split into their four farmlets
- From herd test data, animals with SCC > 200,000 will be sampled for bacteriology of individual quarters and sent away for testing.
- Feed budgets and grazing plans have been updated.
- An increased focus on grazing LI FB paddocks (yellow farmlet) has been made to even up the area grazed across the farmlets.
- Kale dry cows will be used on the weekend to clean up a paddock grazed by colostrum cow’s where the target residual was not acheived.
- Increased use of the farm whiteboard and WhatsApp to keep communication up across the whole team.
- Calved cows are still on 100% pasture.
- SCC has stayed steady around 143,000 which is below last year’s value of SCC 180,000.
- Kale cows will have finished the crop by next week and will go onto predominantly baleage.
- Pasture readings have been varied which maybe due to wet conditions and clumping of grass in some paddocks.
- All herds are sitting above the average pasture cover target line in the spring rotation planner (SRP) and we have ‘banked’ area on each farmlet that can be utilised to minimise damage in wet conditions.
- The farmlet feed budgets are being updated weekly with actual APC information from the farmwalk. No supplements have been required for milking cows to meet the feed budget targets
- Due to the positive staph aureus test, cows identified from the herd test with SCC >200,000 will be sampled and sent away for determination of bacterial infection.
- All quarters are RMT at the 4th milking and must test clear before entering the milking herd.
- Continued supplementation of MgO to springers and milkers and P to fodder beet cows.
- Down cows are blood tested prior to receiving first skin treatment. Initial treatment – 1 bag into the vein and 1 under the skin.
- We are still searching for a new employee to join the team.
- A plan will be put in place to develop policies and procedures for all activities on the farm.
- A daily checklist will be developed for staff to follow and decisions around communication and recording are being put in place.
- In the last 2 weeks we have given out 2 Research Recognition Awards to farm staff who have gone the extra mile to support the research on the farm.
Alex received his for showing great initiative and decision making relating to the feeding of one of the fodder beet mobs
Ben received his for his development of an electronic calving notebook which has enabled the tech team to easily keep up to date with all the calving information ensuring the measurements we have planned occur on time.
- First herd test was completed this week
- Calf measurements are on-going
- Next week we will be taking additional measurements to estimate the N intake of each of the mobs of animals
General Farm Systems information
The project farm systems comparison has been designed to better understand crop-based wintering in relation to consequences for environmental impact and profit
- The four herds are split evenly on age, BW / PW, calving date and breed to ensure the herds are as even as possible.
- Each herd allocated a farmlet corresponding to their herd tag colour Green, Blue, Yellow and Pink.
- Farmlets have paddocks allocated so each herd has equal walking distance from the shed and the same proportion of each soil type and equal proportions of pastures in the FVI trial (forage value trial – refer web site section on research).
The SDH welcome research proposals for any sampling or research on the SDH, these are assessed by the Research Advisory Committee (RAC). Just send your request or ask for information via firstname.lastname@example.org
