Week summary:

  • Weigh and drench R1 heifers
  • Calf shed redevelopment
  • Monitor health of all crop cows and remove animals not eating / putting on weight
  • Winter crop management (accurate fence placement, bale feeders over baleage, plastic wrap picked up, back fences moved up, portable troughs moved, P supplement placed on fodder beet baleage)
  • Team to meet with PrimaryITO for training plans
  • Training on FarmTime timesheet app

Four different farmlets Feed Wedges 15th June 2018

Blue = Low N kale

Green = Standard N fodder beet

Red = Standard N kale

Yellow = Low N fodder beet

Brown = Support block

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).

Feed Management

  • The four herds are to remain on their allocated farmlets always.
  • 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 to be determined for the 2018/19 season.

Comments:

  • Hub kale crops are averaging 12t/ha so PKE is being supplemented to spread out the feed available, fed in feed trailers on the crop paddocks.

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.

Comments:

  • Target cover at the end of May was 2000kgDM/ha. Pasture eaten during the period when herds were being dried off dropped quickly due to ground conditions and high rainfall. Hence target covers by the end of May when all cows were on crop was lower than planned on average by 75kgDM/ha
