The second set of results are now back from the lab, which were the results from one of Leri's pigs - When I received the results I checked with Leri that it was still ok to publish, and she has kindly agreed.
The results for Leri's sample are : 2600 epg strongyloides ransomi (Threadworm)
epg = eggs per gramme of sample material
A count of greater than 300 epg is classed as a high count
A level of less than 100 epg is classed as background acceptable level
It;s interesting that neither Lillian or Leri had seen no indications of a high worm burdon (nothing in the droppings etc) and that in the case of Leri, the ground had never housed pigs before.
Anyway, I personally am now convinced that carrying out a count is a vital element of the worming and rotating plan, and will continue to use and sell the kits.
Thanks to both of you for agreeing to have your results published.
