Spring cleaning

Here/attached is a PDF of Vet Talk in The Land last week (22/9/11)

I will be in trouble with Dr Joe Boray because I forgot to mention the spring (August / September) fluke drench that will be needed on some properties in south-eastern Australia. (Although, I DID mention this in a recent WormMail).

Cost of Worms in southern prime lamb production system   (MLA report AHW.045)

The MLA URL is horrendously long: here is a shortened one: http://tiny.cc/xyvfu   (Otherwise search for ‘MLA AHW.045’ in the search engine of your choice).

‘Southern’ here means South Australia/Victoria. The work was done by SARDI (South Australian Research and Development Institute: ie Ian Carmichael, Paul Blackburn et al)

Ian presented information on this topic at the Australian Sheep Veterinarians’ Conference in South Australia recently (September 2011).

A protocol has also been written as part of the WormBoss revamp but it is not ‘up’ yet.

*WECRT=worm egg count reduction test, aka FECRT(faecal…….).

Of course WormMail has been on Twitter (and the web) for some time: http://twitter.com/#!/wormmail   πŸ™‚

Also ahead of the game is SheepConnectNSW – web, blog, Twitter and FaceBook!  πŸ™‚  ( Like WormBoss News, SheepConnectNSW is well worth subscribing too (you don’t have to tweet)).

This doesn’t mean we are all twits.   I wonder what Roald Dahl would make of Twitter.

Ditch the jargon

"Some jargon is useful as an efficient way to communicate inside a group. But using jargon to sound clever is a way of excluding other people from the group. Our guilty secret is that it gives up pleasure to do this. It reinforces our self-image and makes us seem irreplaceable. It also makes us into tedious, incomprehensible windbags.

WRML.20110909.SheepConnectNSW Update -Yass -17 August – PDFs of talks now on-line

SheepConnectNSW ran an Update for Sheep Producers recently (17 August 2011) at Yass.

It was a great success, with 185+ attendees and a good and varied program. Outside it was raining steadily, so the day was doubly good.

(Major kudos to SheepConnectNSW Coordinator Shelly Anderson and team, incl. the local DPI people at Yass).

The presentations are now online at the SheepConnectNSW website.

See here:   http://www.sheepconnectnsw.com.au/event.html?eventId=324

Even talks that weren’t about worms were very worthwhile.  πŸ™‚

Here is the worm talk:

I believe audio for each talk will also be on-line soon. (‘Not sure if that is a good thing or not :-).

BTW, Phil Graham (DPI Yass) issued a worm warning for weaners for the area. See here:  http://www.sheepconnectnsw.com.au/blog.html?blogId=6

Liver fluke – spring fluke treatment needed??

A reminder from fluke guru Dr Joe Boray for farmers on really flukey properties. ‘A preventive drench will remove the surviving flukes and prevent the contamination of paddocks with fluke eggs before the snail populations multiply in Spring and get infected’.

If you used a triclabendazole-based drench for the late autumn treatment, then you might consider using an unrelated flukicide this time.

Animal Health Surveillance out now

The latest issue of the NSW Animal Health Surveillance is now available. It reports on 12 interesting animal disease cases investigated by DPI/LHPA, and the exotic diseases excluded by this work (look for the photo of the sheep with a headache).

Blowfly resistancehttp://keditchmite.posterous.com/fly-resistance   (Ed Joshua)

OK, we normally confine ourselves to worms here, but lice and flies are up there with worms as the top three health problems of sheep in Australia.

Feed cost calculator – NSW DPI

When you contemplate supplementary feeding (e.g. to meet fat score targets (ewes) or weaner weight targets, with the bonus of improved worm control), this tool might come in handy:

Ed Joshua (Dubbo NSW) warns about L cuprina

(OK…sorry I have strayed onto ectoparasites again… SL)

"They are here already and eating into unprotected sheep. Last week Lucy was eating into new born lamb navels".

"If you …. need details about Lucilure and Lucitrap contact BioGlobal for supplies of these traps and the lure.  They have solved the odour problem by sealing the Lucilure in foil so the traps can be stored without smelling out the storage".

I’m pretty sure Ed isn’t getting kick backs from Bioglobal.   πŸ™‚    

Ed is Acting Ectoparasite Coordinator (like worms, they are notoriously uncoordinated) revisiting his former role while Jemma Turnbull (Bourke) is on leave.

Another song by Arthur Le  Feuvre

(You may already  have heard the WormBoss song at wormboss.com.au)

A message I got from Arthur: "As you know I indulge in a little song writing now and then.
 Coopers is running a song competition for 150 years of being around in the Aus livestock health scene and I have submitted a piece.
You can hear it and vote at http://www.cooperscountry.com.au/song.aspx?aWQCMTk1wqY%3d "    (Too late to vote I’m afraid but you can still listen).

I’m pretty sure Arthur isn’t getting kick backs from Coopers.   πŸ™‚

WRML: Multi-drug (BZ, LEV and ML (incl MOX)) resistant Trichostrongylus colubriformis from sheep in north Queensland, Australia

WRML.20110906: Multi-drug (BZ, LEV and ML (incl MOX)) resistant Trichostrongylus colubriformis from sheep in north Queensland, Australia

 In August this year, the 23rd International Conference of the World Association for the Advancement of Veterinary Parasitology (WAAVP) was held in Buenos Aires.

At this conference, Malcolm Knox (CSIRO, Armidale, NSW) and others presented a paper on macrocyclic lactone (ML) resistance in an isolate of ovine Trichostronglyus colubriformis (black scour worm) from the Mackay area, North Queensland.

Resistance of T colubriformis in sheep to MLs has been considered rare in Australia, although there are field reports (based on worm egg count reduction tests (WECRTs)) from around Australia, especially in uniform and winter rainfall areas, suggesting that ML-resistance in Trichostrongylus sp is emerging (Love S, 2011).

ML resistance is now common in Haemonchus (barber’s pole worm) and Teladorsagia (small brown stomach worm) spp.  Confirmed ML resistant  T. colubriformis has previously been reported in Australia, in an isolate from goats on the Gold Coast of Qld. (Le Jambre and others, 2005.  Incidentally, resistance of this isolate to naphthalophos (NAP) was also inferred).

Knox and co-workers performed a WECRT, using worm free sheep artificially infected with the Mackay isolate, with WECs performed at 42, 44 and 50 days after treatment with moxidectin at the standard dose rate (200ug/kg).

They also tested  the Mackay isolate (MKY) in larval development assays (remember the old DrenchRite(R) assay?), alongside a susceptible isolate of T. colubriformis (McMaster (McM))  and a resistant isolate of T.c of goat origin (Le Jambre and others, 2005.(Mox-R)). Drugs tested in the assay: thiabendazole (TBZ), levamisole (LEV), and ivermectin (IVM).

There was no significant reduction in WEC after treating MKY-infected sheep with moxidectin.

Using McM as the benchmark in the larval development assays, MKY appeared to be more resistant to LEV and TBZ than Mox-R (Gold Coast isolate). For IVM, MKY and Mox-R appeared similarly resistant.

In short, these tests indicated this Mackay isolate of T.c  is highly resistant to (all) MLs, BZs and LEV.

The authors conclude that this is the first confirmed case of this level of resistance in T colubriformis in sheep from Australia, which sounds a warning for other areas where T. colubriformis is a major pathogen and current control is reliant on MLs.
