Answers

1. On properties where liver fluke occurs, when is the most important time of the year to treat for liver fluke?

The most important treatment is carried out in April–May and should be based on the flukicide, triclabendazole, which is effective against all stages of the fluke found in the sheep. If treatments are also required in August–September and/or February, one or both of these treatments should be a flukicide other than triclabendazole (if this was used in April). This treatment rotation will reduce the rate of development of fluke resistant to triclabendazole.

2. When can two lice treatments be mixed together?

Under no circumstance should products be mixed or label rates altered in an attempt to improve the effectiveness of lice control. There are many different effective products from a number of different chemical groups currently available on the market. Mixing chemicals or increasing rates will not make up for a failure in lice biosecurity or inadequacies in application technique.

3. What are the 4 strategies you can use to manage dag and lower flystrike risk?

  • Use worm egg counts to monitor worm burdens and understand the causes of scouring in the flock.
  • Use WormBoss to develop an effective worm management strategy and drench program.
  • Use crutching strategically to remove dags during high risk periods for flystrike.
  • Consider selecting rams that have low Worm Egg Count (WEC) and Dag Score (LDAG) ASBVs and low Dag Scores.
