State Outlooks for November 2018
Monitoring for worm and fly infestations are indicated in areas enjoying rain this month. Young stock could benefit from a summer drench.
|
Worm egg counts are universally low, but testing for any rapid build-up in barber’s pole numbers is advised if storm activity continues. Flystrike is a major issue and Mycoplasma ovis is causing disease in some flocks.
|
Heading into summer the focus is on the summer drench and drench resistance testing. Fly preventative treatments are indicated as the weather is warm and wet.
|
|
Continue monitoring as rain this month could lead to barber’s pole infestations in young stock.
|
Drenching all sheep in summer can significantly increase drench resistance. Check worm egg counts in lambs and treat all weaners and hoggets with a summer drench. Monitor adult sheep. Barber’s pole could be of concern in the higher rainfall areas.
|
|
Quarantine drench ‘mainland’ lambs when they arrive at your property and practice appropriate lice biosecurity measures as necessary.
|
Check worm egg counts in adult sheep every 2–3 months for changes in scour worm populations, and 3–4 weeks after rain in areas prone to barber’s pole infestations. Recent rainfall events could easily lead to flystrike.
