We use Noromectin (not very often).

We use any drench which is recommended for cattle. Ask you local vet, which drench is the best one to use for the worms in your area. Each area has a different concentration of certain types of worms and your local vet or experienced neighbours will be the best source of knowledge regarding the brand of drench to use in your situation. If in doubt, take a faecal sample from your animals (from as many as will give you an average) and ask your vet to look at it under a microscope and identify the types of worms you have on your land, in your animals. This will give him/her the information to make the best suggestion of drench for your animals.

A FEC (faecal egg count) done at regular intervals will tell you how often you should drench or use pour-on on your animals. Drenching too often increases the risk of worms becoming drench resistant. So only drenching particular animals, when they need it, is better than randomly choosing a certain number of weeks between medications. That's the new school of thought that we are being faced with down under. Its a whole new way at looking at drenching.

Steve, I'm not personally familiar with the pour-on you mentioned, but it sounds as though it is in the ivomectin group and they don't control all types of parasites. I think they do not control tapeworm and liver fluke but maybe they are not a problem for you.

If anyone is really keen on learning lots about parasites and wants to do their own fecal counts, I highly recommend the Veterinary Parasitology Reference Manual by William J. Foreyt. It is published in the US by Blackwell Publishing. It is really easy to read, well laid out (spiral binding) and has excellent photos.
