Technical Information

The results of the 2011 round of Quality Assurance Assessments by the Western Australia Government Department of Agriculture and Food have been released. Click here to see the results for the Wormcount lab (Lab 91).

Faecal Egg Counts (FEC's) can be done on an individual or pooled basis.

For the reasons outlined above, WORMCOUNT will treat Wormtest kits as 10 individual samples, and the cost will be $34.00 which includes a larval differentiation and, if requested, a fluke count. I encourage all producers to take that extra fraction of time to write the tag number of the animal on the labelled vial as all results will be reported on an individual basis.

In all cases, it is advisable to consider sampling more than 10 animals. There is greater statistical power in using larger population samples, and having more samples provides a fallback when re-sampling is done and previously sampled animals are found to be "empty".

Larval Differentiations are done by using the remainder of the samples not used in the FEC's and hatching the eggs in an incubator for 7-10 days at 28oC. The larvae are collected, killed with Lugol's iodine solution and placed on a McMaster slide. The first 100 worms seen by the operator will be identified to Genera/species, and their proportions counted and reported as a percentage (%).
