Summary of sheep and cattle worm ecology

To celebrate (yesterday’s) equinox, attached (with permission) is a nice table summarising epidemiological information on a range of sheep and cattle worms.

This is from Dr Justin Bailey’s PhD thesis, 2008.

One of the satisfying things about my job is sharing useful but (otherwise) relatively inaccessible information on worms with a wider audience through WormMail.

I like this table (see attached): I hope you do too.

Questions asked by North Coast (NSW) producers on biosecurity

This from Matt Ball, with permission. This might be of interest:

“Last night (5 Sept., 2013) (we) were at a Cattle Producers forum organised in collaboration with Far North Coast weeds. Far North Coast Weeds focus is to get help with control of tropical soda apple and they are promoting the concept of why you should hold introduced cattle in a small paddock or yards for 7 days before release to wider farm. I gave a talk about why this was also a good idea for a range of animal biosecurity issues. Producers then had over an hour to ask anything they wanted about weeds or animal biosecurity. For your interest I summarise the questions on animal biosecurity. Gives some limited insight into producers focus on parasites etc.

Questions asked by producers
· Why does worm resistance develop?
· What would actually happen if FMD was diagnosed?
· Is it true that cattle would not be destroyed if FMD was diagnosed and you would vaccinate instead?
· Is it a good idea to buy a bull persistently infected with Pestivirus and put it in with your cows so they become exposed?
· Why would I use 7 in 1 vaccine versus using 5 in 1 vaccine?
· Should I use Pestivirus vaccine?
· Do we have orange type drenches for cattle?
· Does combination drenching mean that you give half the dose of each drench type?
· Is it important to remove the scrub on my farm?
· Will rotational grazing help reduce worm burdens?
· Can you guys help get consistent naming for chemicals we buy?
· Is it free to get LHPA services?
· Can you use vaccines again once opened them and vaccinated some animals?

By the way, don’t assume I know the answers to these questions.


Vernal equinox


September Equinox in Universal Coordinated Time was on
Sunday, 22 September 2013 at 20:44 UTC

Converted Time Armidale, New South Wales, Australia
6:44 AM AEST
Monday, 23 September 2013

the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about 22 September and 20 March).
• another term for equinoctial point.

ORIGIN late Middle English: from Old French equinoxe or Latin aequinoctium, from aequi- ‘equal’ + nox, noct- ‘night’.

………. but not exactly 12 hours of daylight.. http://www.timeanddate.com/astronomy/equinox-not-equal.html
