Parasitic infestations of cattle, sheep and goats that can lead to significant economic loss include:
Many parasite infestations of livestock are easily recognised by producers because they have highly visible consequences. Parasites may also be visible on animals or in their environment.
Some parasitic infestations result in clinical signs that can be caused by a number of other diseases, while others can remain silent for weeks or months. Where, in the absence of a drought or seasonal feed shortage, there has been a dramatic change in the condition of animals, the producer should suspect that parasite infestation, disease or mineral deficiency is present and arrange for veterinary investigations to be carried out.
With all diseases, parasites infestations and nutritional deficiencies, assess the risk based on previous local district and/or property history.
Intensification of beef, sheepmeat and goatmeat production systems is likely to increase the risk of some parasite infestations.
