Can we reduce ewe wastage and improve their longevity in a flock?

Why are ewes leaving the flock and can we reduce the level of ewe wastage? On this week’s OviCast podcast, we discuss this topic in more detail with Prof. Paul Keynon from New Zealand’s Massey University.  Paul discusses the reasons ewes are culled and lost out of the system and explains the impact this can have on flock output, lamb performance and costs in the system.  Paul also talks to us about variation in ewe replacement rates in flocks in New Zealand and some of the reasons for these differences among farms.  Finally, he discusses how we can alter management on farms to improve ewe longevity in a flock and improve overall productivity.   For more episodes from the OviCast podcast, visit the show page at:
