State Outlooks for November 2017

Many eastern regions of the country are on ‘alert’ for worm and fly outbreaks. Parasites are not so much a concern in the remaining sheep regions that are still quite dry.

A new area in NSW has been included this month – the Greater Sydney area – outlooks for this high rainfall region will be of interest to those who run smaller numbers of sheep and goats in the temperate regions of the east coast.

NSW

Given the recent weather conditions in the eastern half of the state, worms and flies will be out in full force. Western parts of the state remain quite dry and parasite numbers are mostly low.

Victoria

Mobs with high egg counts need to be drenched immediately, but for mobs with moderate egg counts drenching needs to be delayed until faeces become firm.

Queensland

There’s a worm and fly alert for the sheep regions that have received recent rains.

Western Australia

If worm egg counts are around 200 eggs per gram or more (mob average), a drench is needed, but some of the best-conditioned adult sheep in the mob should remain undrenched.
