Whether you produce sheep for wool or meat, internal parasites can and do cost your enterprise in lost production, how much depends on your management. Without information you could be tearing up money drenching when it's not needed or miss a worm problem that leads to scouring and lost production as a result.
StockWatch results are represented in eggs per gram and split into the basic roundworm types and include comments on any other parasites observed. Results are forwarded within 24 hours of arrival at the Lab.
In sheep the major worm species in the strongyle family include Black Scour Worm, Brown Stomach Worm and Barbers Pole Worm. The eggs of these all look the same. Further testing can ID the species present. When selecting a drench, Brown and Black Stomach worms can be treated together ie you don’t really need to know the difference. It can however be handy to know if Barbers Pole is present when selecting drenches.
Standard Test: Mob average offering simple sample collection, quickly answering if drenching is required or your recent drench has performed.
Premium Test: Mob average including range of 10 samples, which offers producers more detail to make decisions when the risk of infestation is high.
Liver Fluke Testing: A StockWatch Liver Fluke Test is reported as either Positive or Negative. A positive result indicates the presence of adult liver fluke. If positive, management actions are most likely required.
Individual Samples for Genetic Selection: Use the results from individual testing to add "natural worm resistance" selection pressure to your breeding objectives. This is a highly heritable trait and when used in a balanced way can add great benifit to both stud breeders and their clients.
Basic Drench Resistance Testing: It doesn't get simpler. Collect a sample 10 to 14 days after you have drenched to see if the drench you are using is effective or if it's time to rotate your drench. For the best results send a sample prior to drenching to give you a starting point.
This can be done for one mob/ drench or set up as a full test where a mob is tagged with 10 in each group, each group is drenched with different actives and leaving one control group undrenched. A premium test is done on the mob as a whole on day one then samples taken from each test group between day 10 and 14 are sent for testing to see what drench actives are working on that property. Too many generalisation are made often about drench resistance, every farm is different because there a lots of variables, drench history, management practices, topography etc. Just because one drench is proving ineffective on one farm doesn’t mean it won’t be 100% effective on another.
Barbers Pole Dipstick Test: (no extra sample required) This test is best in the warmer months and used if egg counts are high and a grower wants to know if the mix of strongyle eggs observed contains Barbers Pole, and at what level. It is a really useful test for growers wanting an answer fast. The test measures the amount of blood present in the dung which is directly related to the amount of damage being done by Barbers Pole Worm. Results are reported as negative through to high as indicated in the table below. The result comes on the same report as the worm count.
(Haemonchus spp.) Cause anaemia as they suck blood from the lining of the stomach. Signs of a heavy infestation include lack of stamina, pale gums, and possibly bottle-jaw and constipation. Keep an eye on stock in the warmer months (particularly if moist) as levels can escalate very quickly.
Larval Differentiation: (no extra sample required) As strongyle eggs all look very similar a larval Diff can be performed to ID the various types. This takes around 10 days, Eggs are hatched in an incubator the larvae collected and identified and percentages of each type reported.
A StockWatch Worm Egg Count Test will provide quick turn around mob average or individual worm egg counts that will help you decide if you need to drench or if your current drenching program is effective.
