If you already use and external lab for FECs:
One major advantage of learning to perform FECs is the elimination of expensive lab fees to have the some job done by someone else.
The following figures are based on prices for ONE sample from a leading UK laboratory, you can multiply this by however many animals you have/require analysing
External Lab Fee = £136.45 (worms, fluke, lungworm, coccidia, cryptosporidium & giardia)
As you can see, the FEC course pays for itself quite quickly.
If you worm "just in case":
If you worm regardless of the individuals parasite burden, “just so they are covered’, again, this could be a costly mistake, especially for smallholders who have small flocks/herds.
Even the smallest bottle of anthelmintic to treat worms is £30, flukicide £70.
"Just in case" cost = £100 (and the possibility of complying with withdrawal periods).
Based on these calculations, the Ruminant FEC Course will have paid for itself over 2 worming periods.
