It takes 10 to 12 months for many lambs to develop immunity to parasites. Sheep also suffer a temporary loss of immunity around the time of lambing, called the periparturient egg rise.

Step 1: Undertake faecal egg counts on your farm
These can be done through your animal health advisor or vet. This should cover 10% of the flock – a minimum of eight to 10 sheep in every group of 100. Sheep should be healthy and have had full access to pasture and/or feed before sampling.
Step 2: Select the right wormer
Use narrow spectrum products when possible and rotate drenches used. When buying-in sheep always use two different products to treat on arrival. Ms Harmer says one of these should be either Monepantel or Derquantel. “Quarantine the new arrivals for at least four weeks to avoid resistant worms being brought on to the farm,’’ she advises.
Step 3: Ensure products are used correctly
Read the data sheet, calibrate the drenching gun and dose to the weight of the heaviest animal in the group. Adhere to withdrawal periods if lambs are going for slaughter.
Step 4: Perform a drench test to establish if there is resistance
A quick indication of the efficacy of an anthelmintic can be gauged by laboratory testing faecal samples from 10 sheep following treatment. The time the test should be performed after treatment depends on the anthelmintic used:
Step 5: Manage grazing to reduce dependence on anthelmintics
Use low-risk pasture or clean grazing at the start of the grazing season and move to aftermaths mid-season as this can reduce the number of treatments needed.
Step 6: Monitor the flock
Using an EID reader to record performance indicators such as growth rates can quickly indicate if there is an issue. “As a minimum you should be weighing and condition scoring the lambs regularly,’’ says Ms Harmer. Target growth rates – lambs should be doing a minimum of 200g/day.
Step 7: Get advice and a plan from a qualified animal health advisor or vet

What dewormer should I use for sheep?
If you are a small flock owner and you seek advice from a veterinarian about what dewormer to use, chances are your vet will recommend Ivomec. While my experience is anecdotal I know that in ALL cases where my advice was sought after a sheep had died the vet had indeed recommended Ivomec or the flock owner had used it on his or her own account. The question occurs why Ivomec is still recommended so often. I contribute this to two facts: First, veterinarians are often amazingly uneducated when it comes to internal parasites in sheep. Secondly, Ivomec is readily available as a drench or as an injection. On the other hand, Prohibit is far more inconvenient to use. The drench does not come as a ready-to-use solution and must be prepared by yourself by mixing the packaged powder with water. It is not available for just a few animals – depending on the weight the package is good for dozens or hundreds of sheep. (The bolus that used to be the convenient choice for flock owners with just a few sheep is no longer available). Lastly, once mixed with water it expires after three months of storage unlike Ivomec, which can be stored for a much longer time.

A faecal worm egg count is the best decider....your vet may well be happy to carry this out for a very reasonable sum.#N#Over here we always worm about 6 weeks before lambing as this is when the ewe has reduced resistance. (Her body stops rejecting 'foreign protein' as she has to not reject the growing foetus). I then worm the lambs at 6-8 weeks of age and the ewes pre tupping. Other wormers are given determined by faecal egg count.#N#Use a wormer which is appropriate for your geographical location (and hence which worms are prevalent) and use flukicides if fluke is endemic.#N#Older animals develop worm resistance to a certain extent.
