There are many resources to assist producers with parasite control. Here's a quick guide to help you find what you want.
Cattle
Meat & Livestock Australia has developed an 'atlas' of parasite control in cattle which can be used as a reference for best practice parasite control for all the major livestock regions in Australia, found here.
Sheep and Goats
Programs for your area can be found on the WormBoss site. Here you will find regional programs for sheep and goats.
In the north west, we are affected by two regional programs; slopes and plains covers our western country (Walgett, west of Narrabri etc) and the tablelands program covers our eastern country (Tamworth, east of Narrabri). By clicking on your region, you can access the whole control program or quick drench decision guides for your area.
The Wormboss website is a helfpul resource that includes parasite control information as well as a training site.
