A south-west trial is seeking to improve the survival rates for twin lambs in mixed sheep and cropping enterprises.
Preliminary results from the trial by the Willaura Best Wool Best Lamb group project show lower mob sizes lead to better survival but the cost of temporary fencing to achieve the change could be prohibitive.
The project is part of the MLA Producer Demonstration Site program.
Steve Cotton from Dynamic Ag Consulting is managing the project. He said analysis of the first 12 months of data from the three-year project shows that when the mob size is halved there is improved survival.
However, when the stocking rate becomes low relative to the size of the paddock, the number of lambs weaned per hectare goes down.
