Detection of liver fluke eggs in sheep and other grazers.
The Botvanger® filters liver fluke eggs from a manure sample (cattle, horse, sheep, etc.) by simply rinsing with water and then allowing it to settle. It takes five to ten minutes to process one manure sample with the Botvanger, after which, following the addition of a drop of methylene blue, it can be examined under a microscope. The device always works; even if there is only one egg per gram of manure, it can still be easily detected. With the Botvanger, no other substances such as zinc sulfate are needed, meaning no environmental burden or special disposal of these polluting chemicals. By using only water, the eggs do not collapse, making detection and distinguishing them from rumen fluke eggs much easier.
Under a microscope
After rinsing and settling, you can easily see whether and how many liver fluke eggs are present in the manure sample. This allows you to determine whether treatment of the herd is necessary.
The advantages of the Botvanger
Fast
Processing a manure sample with the Botvanger takes 5 to 10 minutes. Microscopic analysis depends on experience and infection level and takes about 15 minutes.
Reliable
Even if there is only one worm egg per gram of manure, the Botvanger detects it accurately. This provides a reliable picture of the infection pressure in your herd.
Easy to use
The Botvanger is designed for practical, no-nonsense use, allowing shepherds and livestock farmers with little laboratory experience to work with it. With simple steps and some microscope experience, you can independently perform a complete test.
Affordable
Detection in 5 steps
This is how you can easily and quickly detect liver fluke eggs in cattle, horses, sheep, and other ruminants.
