Internal parasites can be a major problem for producers. With parasites developing resistance to all dewormers and more farmers producing livestock by ‘natural’ methods, there is interest in looking for alternative ways to managing parasite problems. Management is the most important thing to consider. The whole system affects internal parasites. Nutrition and pasture management can help prevent problems by improving the health of the animals. There are soil organisms that kill or prevent the development of internal parasites. Strategic deworming means planning the timing when deworming is done. This can also be an important part of any management scheme. Little is known about the effectiveness of any alternative dewormer. Changes will have to be done slowly while observing their outcome.
