Faeces Collection -  Worm, Coccidiosis, & Fluke Tests

Collection

  • Collect only fresh samples. Older, harder or drier samples are harder to assess and will lead to inaccurate results.
  • Cattle, Goats, Deer etc.: Collect 10 fresh dung samples.
  • Sheep: Move the mob into a corner and leave for 5 minutes. Move the animals away and collect 10 fresh dung samples.

Mailing

  • Please place no more than one teaspoonful of dung in each small bag or collection tube. Please do not overfill or the tubes will leak.
  • Please seal all the bags and then pack carefully.
  • If sending more than one group, up to 5 mobs may be entered on the submission form.
  • If the weather is hot an ice brick will help keep the samples fresh and prevent worm eggs from hatching.
  • Postage/ freight costs will reduce if all samples are sent in one parcel.
  • Fit as many samples in the envelope as possible, or tape or tie envelopes securely together, leaving one address label clearly visible.
  • If your samples are urgent, consider sending by Express Post. These samples will be given a higher priority.

Special Note For Drench Resistance Tests:

  • The youngest sheep on the property should be used.
  • Before drenching submit a bulk worm egg test (group count) to ensure that there are a minimum of 300 worm eggs per gram of faeces (epg) present.
  • 10-12 days after drenching, collect 10 faecal samples from each group of 15 sheep. This allows for some sheep that may not produce samples.
  • Collect samples directly from the animals not the ground, to avoid contamination with microscopic worm eggs which will still be lying on the ground.

ELISA Tests for Fluke - Blood and Milk Samples

Milk

  • Using a clean, unused 15 mL sample tube, collect 5-10 mL milk from under the cream layer from the milk vat. Avoid collecting the cream layer as this is not used in the test and decreases test efficacy.
  • Hygiene is critical, as contaminated samples can give inaccurate readings. Use only clean, unused collection tubes.
  • It is important that the tube is filled no more than 75%, especially if it is going to be frozen.
  • Seal the tube tightly and keep chilled at all times.
  • If there is a delay in mailing the samples, or if the weather is hot, you may consider freezing the samples before sending. If so, ensure that the sample tubes are frozen upright and that the lids are loose to avoid the tubes cracking. Tighten the lids once the samples have frozen.
  • If there are multiple test groups or vats, label the tubes clearly to indicate which they represent.
  • Ensure the lids are secured tightly before mailing. Place the samples in a sealable bag, one test group per bag.
  • Include an ice brick with the samples. Remember to include your paperwork and to label tubes clearly if there are multiple groups.
  • Send the samples by express post or courier.

Blood

  • We recommend you collect at least 10 samples from a herd, and submit these as two groups of five for more accurate testing. We will then pool the 5 samples and perform two tests per herd.
  • Collect at least 1 mL per animal, into a non-coagulating blood collection tube. Seal the tubes tightly.
  • Label tubes clearly to indicate which herd ID and sample pool they belong to.
  • Allow the tubes to stand for 2-3 hours at room temperature. This enables the clots to retract and squeeze out the serum.
  • Then place the samples in a refrigerator and keep chilled at all times.
  • Ensure the lids are secured tightly before mailing. Place the samples in a sealable bag, one test group per bag.
  • Include an ice brick with the samples. Remember to include your paperwork and to label tubes clearly if there are multiple groups.
  • Send the samples by express post or courier.

Water Collection - Algae Tests

Collect samples of algal scum from the water surface.
We suggest that you wear plastic gloves for the collection, to avoid skin contact with algae, some species of which may possibly induce skin irritation.
As algal samples can rapidly deteriorate - post samples on same day of collection.
Please seal the containers tightly, wind the cotton wool round the outside of each tube and close the pack carefully.
