Improving Lamb Survival

​8 businesses in the group participated in the on-farm demonstration phase of the Lifetime Wool Project and discovered that they could increase their historically low conception rates in Merinos to acceptable levels (130%) using Lifetime Wool ewe management guidelines. However the lambing potential was not being realised due to very poor lamb survival rates and more than 20% of the lambs not being accounted for between scanning and lambing. 

Case study examples found from more than 2000 fetuses only 1000 lambs were being marked. Preliminary investigations found approximately 500 lambs dead in the paddock, while the remaining 500 lambs were unaccounted for, despite vigilant fox management programs. This problem formed the basis for undertaking this PIRD on ‘improving lamb survival’. 

​The aims of this PIRD application on ‘Improving lamb survival’ were; 

  • to improve producers understanding of the key factors affecting lamb survival, 

  • ​to identify the reason why on a number of properties in the group, 20% of the lambs couldn’t be accounted for between scanning and lambing, 

  • to improve producers skill level in managing for improved lamb survival, 

  • to increase lamb survival rates and reduce ewe mortality rates, and 

  • to develop best management practice guidelines for improving lamb survival.
