Snapshot:
  • Profit: stubble supplement mob vs lot-fed mob: $6,244.88 vs $2,077.85
  • Profit/finished lamb: $24.39 vs $7.37
  • Feed consumed/head/day (less feed used): 45% less
  • Daily weight gain (comparable): 295g/day vs 286g/day
Background:

An on-farm experiment found that a mob of lambs grazing a stubble crop and supplemented feed ad-lib, compared to lambs in a feed lot, grew faster with lower feed and labour inputs.

Method:
Duration: 60 days
Quantity: 270 in each group
Stock: 5 month old 2nd cross lambs
Stubble supplement mob: Ad-lib barley seconds (approx. 0.5kg/day)
Ad-lib lentil seconds (approx. 0.5kg/day)
Ad-lib stubble pasture (0.55Ha/lamb)
Lot feeding mob: Ad-lib barley seconds (approx. 0.5kg/day)
Ad-lib lentil seconds (approx. 1.0kg/day)
Ad-lib oats/medic hay (approx. 0.5kg/day)

1. Calves per feed input which was increased from 25 calves to the commercial application of 50 calves per feeder

2. The outputs used the calculator from www.advantagefeeders.com.au/calculating-return-on-investment

3. The outputs includes the costs associated with filling, monitoring and depreciation.

Observations:

Tim Petering, the experiment operator had the following observations throughout the experiment.

On the 13/1/15 (one week before the trial commenced), 60mm of rain fell and this germinated self-sown barley in a 140Ha paddock. Half way through the trial , this germinated feed had “hayed” off.

The lamb that made up the Stubble supplement mob were considered the “poorer” doers because they had the lower growth rates before the trial commenced.

PROFIT $6,244.88 $2,077.85
PROFIT/finished lamb $24.39 $7.37

*This is calculated by multiplying the depreciation rate of 15% by the investment of:

2x NGF1800 feeders and 2x Sliding Gates Hay Feeders for the

Lot-fed mob and

2x NGF1800 feeders for the Supplement mob. This also assumes

that this application of feeders accounts for 50% of their use throughout the whole year.

Recalculating with normal inputs

The trial utilised cost effective feeds (barley and lentil seconds, screened out of the harvested samples) unavailable to most enterprises. Between the start and end of the trial, lamb value decreased from approx. $2.70/kg liveweight to $2.55/kg. It is common for the liveweight value to increase approximately $0.10/kg/month.

If the trial was conducted with the following inputs:

  • Finishing value of $2.90/kg liveweight,
  • Barley valued at $250/tonne,
  • Beans substituted for lentils at $400/tonne; and
  • 10% less barley and beans consumed to account for the lower energy content of the seconds used; profit would increase to $15.30/head for the lot-fed mob and $35.13/head for the stubble supplement mob
Conclusions:

The two mobs had similar weight gain.

The Lot-fed mob grew at 286g/day while the stubble supplement mob grew at 295g/day.

The big difference was the supplement consumed.

The Lot-fed mob consumed 2.04kg/head/day – 45%

less supplement.

Other benefits

Less labour. The Lot fed mob required two vaccinations and required their feeders to be filled approximately twice as often at the stubble supplement mob.

There were no stock losses in the stubble supplement mob while 3% of lambs died in the Lot-fed mob.
