What parasites are on your farm? Are they resistant?

What parasites are on your farm? Are they resistant?
By Lucy Scott, Veterinarian, Anexa Vets Raglan

A key factor in creating a parasite management plan is testing to know which parasite species are on your farm, and what drench these parasites are resistant to.

Faecal egg counts are an indication of your stock’ parasitic burdens and doing larval cultures on these can tell us what worm species are present.
A step further is using these tests to answer the important questions – what drenches are my parasites resistant to, and what drenches are actually going to be effective on my farm?

To do this we carry out a faecal egg count reduction test (FECRT), also called a drench trial. We do pre and post drenching faecal egg counts and larval cultures, from which we can calculate the percentage effectiveness of each drench on each species.

If you want to know the best drenching practice for your farm, give us call for a discussion or book in for a drench trial today.
