Eminent vet parasitologist goes walkabout – RB Besier
Well-known and highly respected veterinary parasitologist, Dr RB (‘Brown’) Besier retires in July (on Bastille Day) from the Department of Agriculture and Food, Western Australia (DAFWA). A Principal Veterinary Parasitologist, Brown has been based for some years in the lab facilities at Albany, WA, from which he ranges far and wide.
After graduating from the University of Queensland veterinary school, RBB spent his formative years as a new veterinary graduate in various parts of WA including a stint in the wilds of the Kimberley region of northern WA. In time, after heading south, he went through a period of intensive training in veterinary parasitology. Brown did his PhD on Haemonchus (barber’s pole worm). Interestingly, he is now involved in Barbervax, a world first (barbers’ pole) worm vaccine that is produced in Albany but hails from Scotland.
Brown of course has been up to his eyeballs in all things parasitological and is known to all who know much about worms and are passingly familiar with the literature. (RBB has has authored nearly 200 scientific publications).
In addition to serving on the executive of multiple professional groups, both national and local, Brown also played an important role in WormBoss, which paved the way for its sibs, LiceBoss and FlyBoss, the three of which make up ‘ParaBoss‘. While Arthur Le Feuvre in particular championed WormBoss from embryonic stages through to early adulthood, Brown at the time led parasitology programs in the Sheep CRC, (which he did for 12 years) and played a vital role in the early and later stages of the WormBoss story. There were others of course – it has always been a team effort – not least the likes of Lewis Kahn (Executive Officer) and Deb Maxwell (Operations Manager) who, with assistance from the ParaBoss Technical Committee, currently guide and nurture ParaBoss (funded at present by MLA and AWI).
Really, Brown is neither retiring (activity- or personality-wise), nor is he going walkabout. He will still be very active, setting up his new venture ‘Brown Besier Parasitology’. RBB will still be involved with Barbervax (local management) and ParaBoss, and also his external (adjunct) role (Adjunct Professor) with Murdoch University. I believe he is theoretically interested in golf, but time seems to be an issue. Not an issue (in no particular order) is finding time to enjoy a good red, his family, friends and his beloved standard poodle.
With heart-felt thanks to Brown, on personal and professional levels, and best wishes for his future.
WormFaxNSW May 2016
‘A smattering of positive liver fluke counts and also some high ‘strongyle’ worm egg counts, many of these dominated by Haemonchus (barber’s pole worm(BPW)). I think a WormTest from Gundagai takes the prize with a WormTest (usually done on 10 samples) returning an average worm egg count (WEC) of ~ 11 000 epgs per gram. Usually you can bet the highest WEC in a WormTest involving 10 individual sheep (sometimes batching of samples is done), will be 2-3 times the average. In this case the highest was about 20 000.
But, high worm egg counts in winter? We have been over this before. There are a number of factors, maybe three main factors. I’ll pick on just one: are the drenches used on this farm effective? OK, I’ll pretend I am a betting man and say that there is a 90% chance the farmer in this case doesn’t have good, recent, objective data on how effective the drenches are on their farm. This is not unusual. OK, one more comment: larvae newly produced in autumn (when it was still warm enough for development of eggs, of BPW for example), will survive over winter, despite frosts, albeit in declining numbers.

Hobby farmer biosecurity risks
Lambex-Albury in August
Lambex is the biggest sheep-related conference in Australia. NSW DPI is a major sponsor. The last Lambex, held in Adelaide in 2014, was a sold-out event, with 930 attending, and another 200 missing out. http://lambex.com.au/ http://www.lambex.com.au/viewStory/2016+Program
NSW DPI’s Lambex coordinator / Lambex committee member is Tracy Lamb (yes, she has heard all the jokes) located at Cowra.

Removal of tapeworm (Moniezia spp.) did not increase growth rates

First new predator toxin in 50 years becomes available
An excerpt: ‘The new baits contain a chemical toxin called para-amino propiophenone (short name PAPP) which causes a targeted and quick death to wild dogs and foxes when consumed. Unlike other predator toxins, these new PAPP bait products have an effective antidote, which needs to be administered by a vet.’

MLA’s and AWI’s Wool and Sheepmeat survey
(From Luke Stephen (NSW DPI Technical Specialist-Sheep Breeding) 2/6/16):
‘MLA and AWI’s Wool and Sheepmeat survey is now open until the end of the month. It can be accessed by clicking the link below.
Further information can be found on the MLA website by clicking on this link:
http://www.mla.com.au/Prices-markets/Market-news/MLA-AWI-wool-and-sheepmeat-June-survey-now-open-02062016 [“We ask that responses be completed by 30 June 2016. Responses received by this date will be entered into the draw* for the chance to win a Caltex StarCash Card worth $1,000*.”]
“These surveys are important as they collect sheepmeat industry livestock numbers and lamb production expectations. Production and producer intentions are regularly monitored to generate better forward looking information that allow producers to make the most efficient decisions, with the results of these surveys forming the basis of MLA’s Industry Projections.”
