Key Decisions: this week

  • Feed planning was challenging this week due to an increasing number of mobs on the farm as cows are dried off and R2’s return to the farm on Sunday. Maintaining fodder beet in the diet of the Std and LI FB herds and minimising the risks of acidosis as they transfer between mobs is the most challenging
  • From Sunday we will have x3 dry mobs, x5 milker mobs and R2’s on farm. After teat sealing the heifers on Monday they will be split into kale and fodder beet mobs and used to open up crop paddocks and start their transition onto crop.
  • We have increased fodder beet allocation to Std and LI FB herds to 3 kg DM/cow/day (1 hour on crop). Any fodder beet herd cows pulled out for lameness or mastitis will stay in the sick mob until dry off which is scheduled for the 25th and 26th May.
  • The remaining cows in the fodder beet herds will be dried off on the 25th May and kale herds on the 26th May. By this time we will have all our crop paddocks opened up so they will be used to minimise the need to have cows on pasture at this time.
  • Based on growth over the last 2 winters and current growth we have decided to drop the cover on all farmlets slightly lower than the original feed budget so while we have dropped below the target line on the graphs we are not panicking at this stage.

Figure 1:  Autumn feed budget tracking against the plan

 

  • 11 young, high BW culls were sold locally this week rather than being culled through the works
  • R1’s return to the support block today. They will be run on grass over the weekend and then split into their kale and fodder beet mobs on Tuesday and the fodder beet calves will start transitioning onto beet. We are targeting 5.5 kg DM intake for both groups through June and 6 kg DM in July. Total allocations, accounting for wastage, are 7.2 and 6.7 kg DM/animal for kale and fodder beet respectively in June and 7.8 and 7.3 kg DM/animal respectively in July.
  • The R2’s will be used to take the top out of x4 springer paddocks across the farmlets. These paddocks are already at 3000 kg DM/ha!. We will take them down to approximately 2300-2400 kg DM/ha.

General Notes:

  • We identified a couple more empties from the herd test so have reduced discretionary culls in the herds affected. Last culls will go as soon as we can get space for them
  • Soil temperature has averaged 10 C again this week but 74mm of rainfall have made ground conditions quite wet in some paddocks
  • Cows dried off last Friday are cleaning up behind the milkers and being offered green chop oat silage and hay.

  • Alternating new grass paddocks will older pastures this week did not prevent the drop in production we have been experiencing when grazing the new grasses. We have enlisted the help of our PGGW agronomist to help us get to the bottom of what might be causing the production drop. While pasture cuts are indicating lower DM the pre-graze mass is still at target or above when they are being grazed and they are not nailing the residuals.

  • Over the last couple of weeks all our young stock (including R2s) have been weighed and measured. When the R2s will return on Friday, they will receive Cu bolus and a short acting Se injection, before being teat sealed. We are still waiting on the LW data to come through from the grazier but the remainder of the data is summarised below.

Animal Health

  • Dusting of DCP continues on the new pasture breaks to FB herds and to dried off cows in their grass paddock. As they move full time onto the crop DCP will be put on baleage
  • To ensure their feet are fully healed prior to winter all the lame cows in the sick mob will be dried off this week
  • Dried off cows are being checked daily when being moved to make sure they are drying down properly.

Research on-farm

  • Our research last winter has provided some practical indicators for when weather and soil conditions start to impact on animal behaviour, especially lying time.

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).

Research Proposals

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 louise.cook@southerndairyhub.co.nz
