Early thoughts on partial flock treatment in summer rainfall regions

by Lewis Kahn, Executive Officer, ParaBoss

Can partial flock treatment (targeted treatment) be successfully used to slow drench resistance in barber's pole worm areas, where the risks are sheep mortality, rather than just body or fleece weight loss? >> Read more.

Was this year's flystrike control a success, failure or overkill?

from the FlyBoss web site

How did your flock fare this summer with flystrike? With the fly season almost finished, now is a good time to review your annual flystrike management plan to ensure strike is controlled, but that you are not doing unnecessary prevention.  >> Read more.

Withholding periods for lice, fly and worm treatments

from the LiceBoss web site

Withholding periods are mandatory with all registered veterinary products used to treat sheep for worms, flies or lice. These periods have been developed to indicate when the chemical residue that remains in or on meat and wool products will not exceed the maximum residue limit.  >> Read more.

I'm crazy...not my fault, not guilty (Toxoplasmosis)

Depending on location and rainfall, barber’s pole has been active and, in some cases, causing death; scour worms have also been on the rise. This means that you should be making some very careful decisions about preparing for late autumn and winter. Poor decisions and management now will haunt you right through to summer.

This is a critical time to make sure you are on top of what's going on worm-wise, otherwise you will be in trouble later. To make these decisions you must know the worm status of the various mobs, particularly weaners, which should be monitored regularly.

Worms should not be a problem because of the ‘now you see it, now you don't’ rainfall patterns and ongoing warm/hot weather in between. Having said that, if you have been doing OK for rain, do not forget to do a few WECs to be assured worms are not sneaking in the back door, unseen.

Autumn is a critical time for sheep worm control, as the action taken now largely determines the risk of winter and spring worm problems. Make sure you are taking appropriate management action to prevent nasty surprises later.

>> full report

Despite very dry conditions, stock are doing well and worms are not a big problem. However, do not forget to do some monitoring, particularly of weaners. Be careful if you have scouring sheep that are not responding to drenching—bacterial scours are likely the cause. These scours are unlikely to respond to the normal treatments for coccidia. Seek advice.
