Snapshot:
  • Weaning rate: creep-fed vs control: 159% vs 139%
  • Value of lamb/ewe (creep-fed vs control): $107.16 vs $78.06
  • Daily weight gain to weaning: 211g/day vs 168.8g/day
  • Net value less feeding expense/ewe: $92.55 vs $78.06
Background:

An on-farm experiment found that a mob of spring drop ewes carrying twin lambs that were supplemented into lambing and then their offspring up to weaning produced considerably more meat compared to another mob that had no supplement.

Method:
Duration:Total:
Ewe feeding:
Lamb creep feeding:
135 days
40 days
95 days
Quantity:97 ewes in the supplement group and
99 ewes in the control group
Scanning:All ewes scanned with twins
Ewe age:3 and 4 year old
Ewe breed:Merino
Ram breed:Merino
Lambing period:1/8/14 to 4/9/14
Diet:Supplement group:
Ewes: 300 grams/day of Triticale
Lambs: 200 grams/day of Triticale
Control group:
No supplement
Both groups:
Continual access to pasture higher than 1200kg/DM

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:

Mac Fraser, the experiment operator had the following observations throughout the experiment:

“On the 2/08/2014 we had an outbreak of Campylobacter confirmed and it was recommended to get them off the feeder, which we did.

Two weeks later on the 16/08/2014 we decided to recommence the trial as the Campylobacter had settled down after injecting mobs with antibiotics. It has been a trying year but the trial has shown us the great benefit in creep feeding twin lambs.

We have also used the feeders to supplement ewes in autumn. Ewes that were on the feeders scanned at 147% while ewes without feeders scanned at 112%.”

*This is calculated by multiplying the depreciation rate of 15% by the investment of a feeder ($2,200) and dividing it by 97 ewes. This also assumes that the feeder is used only for this application throughout the year.

**The feeder was filled twice, taking one hour to fill both feeders each time at $60/hour to fill.

Conclusions:

Lambs that were creep fed with Advantage Feeders averaged a weight of 27.0kg at weaning while the lambs in the control mob average only 22.4kg.

With an estimated lamb birth weight of 4kg, the creep fed mob grew 25% faster.

The weaning rates were substantially different. The supplement mob achieved 159% while the control group were at 139%.

Other benefits include

  • Lambs were imprinted with the knowledge to feed from feeders after weaning, reducing the occurrence of a weaning check.
  • The ewe lambs from the creep feeding group have a much higher likelihood of reaching target mating weight.
  • Lambs reach marketable weight earlier freeing up more area to run ewes.
Recommendations:

The experiment shows that the creep fed group grew considerably faster than the control group and were more profitable in both the pre and post weaning periods. The creep fed group weaning rate was 20% higher than the control group and daily weight gain to weaning was 43gram greater. From these results the recommendation is to continue on with this new feeding program.
