State Outlooks - July 2017

There are frosts on the ground, yet sheep in some areas are wormy, having picked up ‘autumn-born' larvae off the pastures in recent months, or carried over existing burdens from late summer. As pastures shorten in length due to dry conditions stock grazing closer to the ground are at greater risk of becoming infected in the weeks ahead.

If you wonder about the value of WormTests, read the case study by Kate Sawford in this month's NSW reports.

New South Wales

A discussion about why barber’s pole worm burdens are high at this time of the year and also the value of worm testing individual mobs. Some areas of the state are experiencing dry conditions, so worm levels in these sheep are generally low.

Weaners currently need to be monitored every 2­–3 weeks, with older classes of sheep monitored every month.

Frosts have stopped barber’s pole eggs from hatching, but existing larvae on pastures remain unaffected.  

Western Australia
>> full report

The focus for worm control is now on the ewes with lambs at foot. Short pastures have forced sheep to graze closer to the ground and so are at risk of picking up infective larvae.

Worm egg counts in Merino ewes have started to rise as stock graze closer to the ground.

South Australia

Monitor worm counts in lambs from marking onwards, as restricted ewe feed intake will reduce lactation production forcing lambs to graze closer to the ground.
