Lamb Production on Grey Calcerous Soils

Summary

In some paddocks, lambs were shown to be severely deficient in cobalt by lamb marking, which could be affecting life time productivity of these sheep. Further investigation needs to be completed to determine both the long term impact of, and how to address, cobalt deficiency. As a result of the project, group members have changed their mineral supplementation and drenching programs. Supplementary feeding has also been used to manage the nutrition requirements of young sheep and to prepare ewes for mating.
