2017/18 Season HUB Weekly Farm Update as at 2nd February 2018
All smiles this week with a bit of moisture (55.6mm rainfall on the 2nd Feb)
All smiles this week with a welcome rain of 55.6mm on the 2nd Feb. Urea had been applied to 92ha at a rate of 25 units/N/ha a couple of days before the rain so this will help the pastures respond from the dry period. The current round length on the platform will be maintained at 30 days and pasture growth monitored. As growth increases supplements will continue to be offered, giving the pastures time to respond to the moisture and N, to lift average pasture cover (APC).
Critical Targets this week
- Continue to monitor SCC
- FarmTune workshop
Herd & Production
Four herds split evenly on age, BW / PW and on the winter crop trial treatment groups 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).
Staph Aureus has been identified in approximately 40 cows at The Hub. A high bulk SCC and cows not reacting quickly to treatment encouraged investigation leading to this diagnosis. Infected cows have drafted out and are being milked last to prevent the spread of this infection.

The four herds are to remain on their allocated farmlets at all times. The 2017/18 season aim is to feed all cows in a similar manner all season. Any differences to be recorded. Decision rules for Cows of BCS 4 or less are that they can be fed extra supplement in the shed as required by the farm team and be milked OAD but will remain in their allocated herds for research purposes. The concentrate in the shed is a 50:50 mix of PKE and barley.
Average pasture cover was measured and had lifted from 1770kgDM/ha to 1915kgDM/ha. This was unexpected and as mentioned may be a result of a small amount of moisture from the week before.
Residuals are holding between 1500 – 1550kgDM/ha, with approx. 7 – 8 kgDM/cow/day of pasture being offered.
Supplements being offered to all cows are:
- 1.0 kg/cow/milking of PKE/Barley 50:50 mix in the shed;
- 1.0 kg/cow/day of PKE in the paddock;
- Remainder being made up of pasture silage to meet the 16 kgDM/cow/day intake target.

Land, Pasture, Crop & Silage Management
Total area is 327ha(eff), 32.5ha(eff) young stock block and 294ha(eff) platform. Winter crop is grown on both blocks for all stock. Crop rotation is two years in crop then re-grass. PGG Wrightson grass cultivars used are Rely, Platform and Excess, all diploids. Where target residuals are missed, topping after grazing is the tool the farm team use as needed.
The R1 heifers have all been split into mobs of approx. 10 animals and spread evenly across the platform.
DM% results are back for the silage stack remaining on farm at 29% DM. ME was not measured at this time.
Table 3: Land, Pasture, Crop & Silage Metrics
There is a question on the growth rate recorded this week of 44kgDM/ha/day which is more than expected. However, this has been recorded on other farms and it follows 7.2mm of rain the week before.

|Post - Graze cover target||kgDM/ha||1500|
|Average Pasture Cover (avg. over 4 farmlets)||kgDM/ha||1915|
|Growth Rate (avg. over 4 farmlets)||kgDM/ha/day||44|
|Rotation Length (avg. over 4 farmlets)||days||30|

Research Update (fortnightly)
Last update was last week.
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
For more information check out the DairyNZ link:
- Advertising and interviews continue for another permanent employee to lift our team to 5 permanent farm staff for the rest of this season and into the next. https://www.southerndairyhub.co.nz/jobs/
- Another FarmTune session completed – now we are into planning and for setting up workspaces, cowshed and workshop. Will keep you posted.
Early changes as a result from our time with Lynsey doing FarmTune. Animal health cupboard easy access, correct height, with products set out and with listed treatments for each cow in the treatment mob, along with a re-order sheet
