WRML. Drench efficacy (sheep) and market share of drenches – New Zealand Dr Andrew Dowling

TO: WormMail list (recip. undisclosed).

Trans-Tasman taunts aside, we do get good intell. from our Kiwi cousins. (They’re not just the best Rugby players in the world :-)….(Although the Brumbies and The Bulls (N Transvaal) are the only provincial sides to have beaten the Lions in recent decades…).

Dr Andrew Dowling (Christchurch, NZ) recently shared this information with me and gave permission for it to appear in WormMail.

I have made some slight changes, including the addition of some notes, and a graph.

"Stephen,

I have been analysing the lamb FECRT tests we have conducted over the past 2 years (19 in total and spread over NZ so the sample size is small but the farms were not chosen due to any specific concerns about anthelmintic resistance). The results seem to be in line with other surveys published over here and are alarming to those who deal with parasite advice on farms but obviously not as alarming to those purchasing and administering the drenches as indicated by the drench sales table. The percentage of farms who have at least one parasite resistant to an anthelmintic group is very high for the drenches tested (triples and abamectin-lev combinations were not included).

PGW make up around 13% of the oral drench sales in NZ if you can really believe any of the market data. The table of the drench sales show a significant move toward the triple combinations and also the abamectin levamisole combination as a step up from BZ Lev for those who can’t quite stomach the use of a triple yet! Moxidectin though is still static with farmers concern about Haemonchosis (nothing like as severe as you see in Australia) prompting them to use 2-3 drenches in lambs in the summer and autumn. The efficacy at day 10 against Haemonchus is still good but we are losing efficacy against other pathogenic parasites. Zolvix is slowly gaining acceptance with some farmers as a quarantine drench and also as a ewe hogget “clean out” drench in the autumn.

In NZ the lamb is considered to be the major contributor of parasite eggs and thus infective larva on pasture so drenching lambs at 28 day intervals from weaning (around 80 – 100 days of age and some drench prior to weaning at around 70 days of age) until the lambs are around 9 months old is commonplace. The drench interval is then extended as the immune system of the lamb becomes more competent. Adult sheep drenching may be done pre tup in Haemonchus prone regions and prelamb drenching of ewes is another common practice with the long acting capsules and injections (not included here).

Andrew"

Notes:

FECRT = faecal egg count reduction test. See: http://www.wormboss.paraboss.com.au/tests-tools/tests/testing-drench-effectiveness.php

‘Triples’ = combination of three unrelated broad-spectrum actives. For more information on this and on BZ, LEV, moxidectin, ‘Zolvix’ etc, see: http://www.wormboss.paraboss.com.au/drenches.php

‘Tup’ = ram/joining.

SAD and the northern solstice

Winter and short days don’t appeal to me a great deal (those at latitudes greater than say 40 degrees* will laugh at this) but a few years ago I changed the way I think about it.

The northern solstice (winter solstice in Australia etc) is tomorrow, Friday 21 June, at 15:04 AEST (= UTC +10). (UTC is approximately the same as GMT).

So, after tomorrow the days get longer! Sure, due to seasonal lag, we also get our coldest weather in the 6-8 weeks post-solstice, but we are getting more hours of daylight. ! 🙂

So, SAD begone! 🙂 (Going for a lunchtime walk now in the sunshine…)

*(Some latitudes: Hobart AU = 42°50’S, Sydney AU = 33° 52′ S, Perth AU = 31° 60’S, Armidale AU = 30.52 °S, Brisbane AU = 27°25’S, Pretoria SA = 29° 12′ S (centre is approximately 25 degrees 44 minutes?), Christchurch NZ = 43.33 S Palmerston North NZ = -40.35, Edinburgh SCO = 55.95 N)

WRML. ASAP-Sheep CRC-DPI-Sheep Production Seminar Cowra 29 May 2013-Ed Refshauge and Hopkins

To: WormMail list (recip.undisclosed) Also posted to: www.wormmailinthecloud.wordpress.com

Attached are the proceedings for the ASAP-Sheep CRC-DPI-Sheep Production Seminar Cowra 29 May 2013.

This was a good meeting, not just because there was talk about worms.

If like me you prefer pictures to slabs of text, the worm talk (PDF of the PowerPoint) is also attached.

The worm talk has some new information on likely prevalence of drench resistance in certain regions of NSW.

In addition to information on prevalence, there is also some information on severity of resistance (of worms to anthelmintics for sheep).

In other news…

Consultants who until recently were NSW DPI professionals

Attached is a list that might be of use/interest. I may update this: I am sure it is not exhaustive. (Use the zoom function (e.g. 150%) in your PDF reader (Adobe or other) to read).

I have heard there may be a similar list on LinkedIn, but I don’t use LinkedIn.

Resistance to Zolvix

This has been reported (January, ISVC) in goats in NZ. I’ll talk about this some more.

WormBoss News – May

It’s coming. ‘Time to subscribe to WormBoss News: http://www.wormboss.com.au

If you work with (sheep etc) parasites at all (‘not talking about your colleagues), you need WormBoss.

Flies for Food http://www.abc.net.au/catalyst/stories/3775080.htm

Fascinating program. Who said parasites were all bad?

SOO and RU

Will the Blues (NSW) get done in the State of Origin?

And, in RU….so, the Brumbies vanquished the British and Irish Lions. 🙂 (ABC: ” The win in front of a crowd of 21,655 makes the Brumbies the first provincial side to beat the Lions since South Africa’s Northern Transvaal in 1997, now known as the Bulls”.)

Do you care? (If not, that is OK too).

Prism and Privacy

If you want an alternative search engine to Bing/Google/Yahoo, there is also Startpage or sister Ixquick. (‘Said to be more private/secure; and not returning personalised search results))

http://searchengineland.com/startpage-ixquick-surpass-3-million-daily-searches-163379 https://startpage.com/eng/prism-program-exposed.html

Using Google etc of course is very convenient (they do make some cool / useful apps etc !!), and, as a music album title says: ‘Give me convenience or give me death’. 🙂
Do you care? (If not, that is OK (by me) too).

Some interesting quotes (whether I agree or not)

Jonathan Green @GreenJ
“What the human being is best at doing is interpreting all new information so that prior conclusions remain intact.”

News is bad for you – and giving up reading it will make you happier
‘News is bad for you. It leads to fear and aggression. It hinders your creativity and makes you sick. We should stop consuming it, says Rolf Dobelli, who’s abstained for years.’

(I found the source for this (http://www.guardian.co.uk/media/2013/apr/12/news-is-bad-rolf-dobelli) using Startpage 😉

WRML. Economics of sheep worms – Vet Talk, The Land

To: WRML mailing list (~ 400 subscribers; recip. undisclosed)

Attached is a scanned copy of the article in the Vet Talk column on the ‘economics of sheep worms’ in last week’s edition of The Land newspaper (mainly NSW).

This is an expanded version of an article by Lewis Kahn in WormBoss News (April 2013), citing work by Gareth Kelly, who currently works for Virbac.

The editors did a very nice job except for a slight glitch (perhaps due to unclear directions from the author) regarding the table (see note appended to scanned copy-attached).

This is a New England example; the details, but (arguably) not the principles, will vary from region to region and farm to farm.

The top two tools for smart worm control? W + W = (regular) WormTesting + WormBoss (regularly read and applied). (or, W2?? )
