Farmlets Feed Wedges 20th July 2018

Blue = Lower intensity kale

Green = Standard fodder beet

Red/Pink = Standard kale

Yellow = Lower intensity fodder beet

Brown = Support block (not measured this week)

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).

Cows BCS results this week compared to 05/7/2018:

Standard Kale Red Lower intensity Kale Blue Standard Fodder beet Green Lower intensity Fodder beet Yellow
BCS R2 (21/6/2018) 5.6 5.8 5.7 5.6
BCS R2 (05/7/2018) 5.9 6.0 5.9 5.6
BCS R2 (19/7/2018) 5.7 5.7 5.7 5.5
BCS MA (21/6/2018) 4.7 4.8 4.7 4.7
BCS MA (05/7/2018) 5.3 5.2 5.1 4.9
BCS MA (19/7/2018) 5.2 5.1 5.1 5.1

Comments:

  • Data suggests that the BCS of the R2 animals in all but one herd has slipped slightly in the last 2 weeks which may be the result of redrafting the animals into calving mobs 2 weeks ago. As a result, the R2’s have moved from a mob of predominantly their own age group to one with a higher proportion of mixed age cows which they will be competing with.

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:

  • PKE feeding in the kale diet has finished and the proportion of kale in the diet increased
  • Feed allocation to kale cows has been reduced based on BCS targets being achieved. Estimated ME intake is now 120 MJ/cow/day 
  • Feed allocation has remained the same to the fodder beet herds as a higher proportion of the herd was less than BCS 5 at the last assessment. Estimated ME intake of 135 MJ/cow/day is targeted.
  • Fodderbeet residuals from the R1 herd have visually reduced suggesting their intake has improved.
  • APC across the farmlets continues to increase with growth rates between 7-10 kg DM/day in the last fortnight.

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:

  • The kale paddocks currently being grazed are averaging 14.2 T DM/ha which is an improvement from the 12.0 T DM/ha in the earlier grazed paddocks
  • Fodder beet yields have remained very similar 21-22 T DM/ha but the proportion of leaf has declined from 25 to 20% between mid-June and mid-July.
