Projected green herbage available relative to historic variation

KEY
HISTORIC
Current Growth
(modelled)
0kg/ha/day
Summary
  • There is currently no green herbage available
  • Poor conditions until December 26 will result in pasture availability in the bottom 25% of years on record
  • Average conditions will see pasture availability in the bottom 50% of years on record
  • Really good conditions will see pasture availability in the top 10% of years on record

Plant available soil water (modelled)

Current PAW
(3 day average)
0mm
Summary
  • Plant available water (calculated as an average over the last 3 days) represents water held across the entire pasture root zone
  • At this time of year, for the wettest 10% of cases the soil has held 34mm or more and is currently holding 0mm
  • Currently the PAW is dry relative to historic variation

Ground Cover

KEY
Current Ground Cover
0%
Chance of falling below the minimum ground cover target
(if no changes are made)
0%
Summary
  • Ground cover should be managed carefully and maintained at over critical level of 70% to prevent erosion
  • Current ground cover of 0% is less than the minimum ground cover target
  • There is a low risk (0% chance) of dropping below this level

Female Condition Score

KEY
Current condition score
0
Summary
  • Condition scores are currently well below average for this time of year
  • Poor conditions until December 26 will result in a condition score well below average, supplementary feeding is likely to be required
  • Average conditions will see a below average condition score, supplementary feeding may be required
  • Really good conditions will see a below average condition score, supplementary feeding may be required

Stock Weight

KEY
Summary
  • Potential liveweight of weaned male progeny from the forecast pasture levels
  • There is a 50% chance of animals reaching 22.4kg by the end of the Forecast Period
KEY
Male weaners average weight
22.6kg
Female weaners average weight
34kg

Feeding Projections for Weaners

KEY
Summary
  • The amount of supplementary feed per head per day and the time when feeding will start at 3 percentile levels
  • Feeding is estimated to start on September 01

Total Supplement Fed

KEY
Summary
  • The probability of the total supplement fed in the three month forecast period exceeding the value shown on the horizontal axis (kg/head) for the 3 age groups of females
  • There is a 10% chance of needing to supply feed to maidens, a 50% chance for mature females and a 100% chance for weaner females
