Derrypatrick Farm Notes Week Beginning August 6th

General Details

  • 96 cows and 96 calves, 29 replacement heifers, 99 steers/heifers currently at grass

Breeding

  • A pregnancy scan is scheduled for the 19th of September

Animal performance

  • All animals were weighed this week
  • Calves are currently receiving 1 kg per head concentrates through creep feeders
    • This was implemented during the drought to ensure calves were continuing to receive adequate feed when baled silage was being fed in the paddock
    • The decision has been made to maintain the calves on creep to ensure animal performance is not affected by removal of the supplementation
    • These animals are currently getting 4 kg concentrates
  • Steers/heifers are currently receiving 2 kg per head concentrates
  • 20 animals have been selected for finishing

Grass

  • Farm was walked on Monday and average farm cover has improved significantly (AFC 627 kg DM/ha)
  • We had an increase in growth this week compared with previous weeks (41 kg DM/ha/day)
  • Both grass growth and quality have improved over the last week
  • Average pre-grazing yield for this week has been 1300 kg DM/ha at a dry matter of 20.1%
  • We are no longer feeding baled silage to cows as of 30th of July
  • We currently have 11 days grass ahead of us
  • We have closed area for second-cut silage (18 hectares; 27% of total area)
    • Three bags of CAN/acre was spread on the second-cut silage ground
  • We will continue to walk the farm to monitor grass growth and will make management decisions based on our weekly farm walks
  • No fertiliser had been spread for a month previous so the decision was made to blanket spread the farm with fertiliser on the 25th of July
    • The whole farm received 1 bag of CAN per acre
  • One bag of CAN/acre (27.5 units of N fertiliser) is now being spread following each grazing
  • We are ensuring a post-grazing sward height of <4.5 cm to ensure we are utilising all available grass we have
