Parasite Test Results | N & W Livestock

HOW ARE THE TESTS PERFORMED?

The McMaster technique uses a special counting chamber which enables a known volume of faecal suspension (0.30ml) to be examined microscopically. If a known weight of faeces (2g) and a known volume of flotation solution (28ml) are used to prepare the suspension, then the number of eggs per gram “[EPG]” of faeces can be calculated.

Below are examples of parasitic eggs however not all of these parasites can be detected with the McMasters test. In some cases a variation of testing techniques and larval cultures may be required.

TREATMENT PLAN

GENERAL TREATMENT ADVICE

The below table provides a general guideline as to when treatment may or may not be required. In certain circumstances a low EPG may require immediate attention dependant on class of parasite and other clinical signs e.g. Low Famacha Score.

Strongylid, Nematodirus, Strongyloides Detection:

Under 200 EPG = Negative or Very Low Worm Burden – No need to worm
200- 500 EPG = Low to Moderate Worm Burden – (Suggest horses in this category are wormed)
500 – 1200 EPG = Moderate Worm Burden – Drench Probably Required (Seek Advise)
Over 1200 EPG = High Worm Burden – This level of worm burden requires attention.

Coccidia Detection:

Low Level – No Action Required (Monitor and Retest in 6-8 weeks)
Moderate Level – Consider Treating (Seek Advise)
High Levels – Treatment is required urgently.

PARASITE CLASSES

The “class” of parasites seen will provide suggestions as to the type of treatment that may be required.

A Natural Alternative

For small scale hobby farms with a few different animals we absolutely love this product.

Livamol with BioWorma is a nutritional supplement containing the natural biological control, BioWorma, that captures and consumes infective worm larvae (including chemical resistant/anthelmintic multi-resistant larvae) within the manure of grazing animals.

Livamol with BioWorma will begin to work immediately within the manure of treated animals, and for best results may be fed continuously when climatic conditions are conducive to BioWorma and parasitic nematode activity.

Faecal egg counts (FECs) may be useful to monitor the effectiveness of the worm management strategy. Other options may include faecal egg count reduction test (FECRT) and/or identifying worm species by using faecal larval cultures (FLC).

LIVESTOCK DRENCHES

The advice on when and how to drench livestock has changed. Routine drenching is discouraged. It is recommended that routine testing be conducted and treatments given only when required. Drench resistance is a GLOBAL now a problem.

HORSE WORMERS

The standard practice of worming horses regularly is outdated and dangerous. It is no longer recommended to routine worm, instead it is recommended to routine test and worm ONLY when required.

COCCIDIA TREATMENTS

Coccidia, a member of one-celled (protozoan) parasites, is at low levels is no cause for concern. The problems arise when an animals health is compromised such as parasite burdens, pregnancy & stressful events. This can now be fatal.

FAECAL TESTING EQUIPMENT

The technique used to identify worm egg counts isn’t difficult, with the correct equipment anyone can do it. A microscope that is capable of 100x magnification (10x objective x 10x eye piece) with a mechanical (movable) stage is key.
