I'm intersted to hear how you're getting on with lambing? What feeding strategy have you employed and is it working for you?
Have you seen this presentation from last year's Best Wool/Best Lamb Conference? https://www.youtube.com/watch?v=srjWJbf48H4&feature=youtu.behttps://www.youtube.com/watch?v=srjWJbf48H4&feature=youtu.be
Amy Lockwood, from Murdoch University, has done research on the impact of mob size and stocking density on lamb survival. Some of her work indicated significantly greater survival (6.2% higher survival, 12.4 lambs/100 ewes in twin mobs) in smaller mob sizes particularly at low FOO (<400kgDM>
She indicates in question time that there haven't been any research trials done on using self-feeders vs trail feeding on the impact on lamb survival, but hopes that they can put a project together to do this down the track.
