The aim(s) of this trial were to demonstrate an improvement in twin lamb survival by reducing mob and paddock size with temporary fences during lambing and demonstrate the cost-benefit of using temporary fences and the ease of construction and removal.
This trial was conducted on Merino ewes and Composite ewes across four properties in the Willaura/Lake Bolac areas of western Victoria between 2017-2019.
Over the life of the trial, there was a 4.8% improvement in lamb survival across the participating properties.
For producers from the Willaura BestWool BestLamb (BWBL) group to demonstrate:
- how temporarily reducing paddock and twin ewe mob size during lambing can increase twin lamb survival by 10% (measured by marking percentage relative to mob allocation to paddock)
- the ease at which temporary fences can be constructed and removed
- that temporary fencing is a cost effective strategy to employ rather than increasing single bearing mob size to free paddocks up for twins.
- Across all farms, years and stocking rates there was a 4.8% improvement in twin lamb survival, representing a 9.8% improvement in lamb marking rate.
- Over the trial period, a 301% return on investment over the trial period was demonstrated.
- The total net benefit over the trial period was $2.78 per ewe, $20.73 per hectare and $15.06 per lamb.
