Faecal Worm Egg Counts

We now have the facilities to carry out in house faecal worm egg counts. With resistance to the main classes of wormers increasing, the focus is on reducing dependence on wormers. For this to be done effectively it is important to find out the worm burden of the sheep on the farm, to help decide whether or not worming is required. Faecal egg counts should be done throughout the season, with the frequency depending on the farm (permanent or not, clinical signs occurring etc).

Ideally fresh faecal samples from 10 representative animals within a group are taken from the rectum of the animals and brought in separately for individual analysis. This gives us the most information. However useful information can still be gained from collecting fresh faeces from a number of animals and pooling the samples (and yes, you can pick them from the floor if it's going to be difficult to collect from the rectum, but make sure they are fresh).

If we receive the samples in the morning, we can get the results back to you that afternoon, by email or by phone. Results from samples received in the afternoon will be returned by the following morning.
