A project at the Graham Centre for Agricultural Innovation has identified a possible way to boost lamb survival.
Following analysis of forage, blood and urine samples from 16 farms across four states, a potential link has been identified between the higher calcium and magnesium status of ewes and improved lamb survival.
Researcher Dr Shawn McGrath said survival rates are a “reasonably big issue” for farmers.
Industry benchmarks suggest 70-80 per cent of twin-born lambs live to marking.
A study across five farms is currently underway to identify whether supplementation improves survival. If demonstrated, this may represent a quick and simple way to strengthen flocks.
“It’s a very easy thing for farmers to be able to put out supplements,” Dr McGrath said.
The on-farm studies will be completed this spring.
