Aside from drenches at one or two strategic times, the mob’s average worm egg count should be the basis for drenching decisions.
For those who like to see all the information and simply read through it in order. Each heading is a link to a page of information—the dot point provides a summary of the page.

Collect the number of samples per mob as recommended by your laboratory.
Ideally this would be from at least 20 goats – or, if you have less than 20, from all the goats you own.
WormTests can be done at any time; however there are certain routine times to WormTest (preferably with a larval culture):
A WormTest refers to a ‘Worm Egg Count Test’ or ‘WEC test’; it will identify the number of worm eggs in faeces, which is a good indication of the worm burden of the goat.
Some laboratories can also perform a ‘Larval Culture’ (also called a ‘Larval Differentiation’) to identify the types of worms present and their proportion (the importance of this varies according to your location).
There are six common strategic drenches; not all are used in every region.
The WormBoss programs outline which strategic drenches to use in each region – you may wish to refer to both the Smallholder program and the one for your geographic region.
