As with carcase traits, over time Rick has been working with the tools available to further parasite resistance and resilience in the St Leger flock. These have included:
- blood testing
- saliva testing
- genetic testing
While not recording FEC, these are monitored.
We have a minimal drench and drench resistance programme. No capsules are used. Until last season breeding ewes had gone 5 years without drenching at all.
Again 50k GbV will aid in selecting sire rams with greater resistance and resilience.
