Loving these new pen-side liver fluke antibody test kits for cattle and sheep. Absolute diagnostic game changer. Rapid, affordable, easy. Whatโs not to love?!
Liver fluke antibodies can be detected from 3 weeks post infection. This is the earliest method of detection we have available. Liver fluke antibodies can persist for a long time, so for this test we recommend only testing first-year grazing cattle or sheep (adults could have high antibodies from prior exposure, yet currently have no liver fluke present). Prior to this new lateral flow test, samples had to be processed at external laboratories, increasing turnaround time and cost. This test provides results in 10 minutes and can even be undertaken by farmers themselves, as only a prick of blood is required, which can be taken from the nose or ear with a lancet supplied with the test kit.
Alternative tests for liver fluke are antigen testing faecal samples, or egg counting faecal samples. These tests can be used on adult animals, but will not detect infection until 7-12 weeks after initial infection.
The choice of test will be dictated by several factors - speak to your vet to determine the best method for you and your stock. This will almost certainly change depending on the time of year. The number of animals required for testing will also vary, depending upon the number of management groups on the farm and the total number of animals present.
This beef suckler farm tested negative: no liver fluke โtreatmentโ is required, saving the client time and money, whilst being responsible with the use of flukicide products.
Take home = test and only treat when necessary.
