The Levawright Drench is a broad spectrum dewormer against gastro-intestinal and lungworms. Drenches are one of the most common wormer delivery methods for livestock (cattle, sheep, and goats), but are less common for pigs and rare for poultry. They’re also used for pets, though they’re more popular with cats and puppies than with dogs.
The Levawright drench contains a mixture of active ingredients to cover a broader spectrum of activity, i.e. to control more parasites simultaneously. It also combines different chemical classes in order to overcome resistance of certain worms to anthelmintics, which is very common in sheep and goats and occurs also on cattle. It targets mainly parasitic worms such as gastrointestinal and pulmonary roundworms, gastrointestinal tapeworms and flukes.
Correct administration of drenches to livestock
The following are important points to note when administering drenches to livestock:
- Drenches are administered to livestock using drench guns.
- It is required to restrain the animals before administering the drench.
- Shake the container before use.
- Calibrate the drench gun correctly.
- Ensure that each animal gets the correct dose corresponding to its weight.
- As the liquid in the container evaporates, a vacuum forms, making it increasingly difficult to drench the next dose. This is usually not an issue if the container is collapsible. If the container is not collapsible, it must be opened to allow air to enter and compensate for the vacuum.
- Ensure that the animal has really swallowed the whole dose.
- Use the drench gun correctly and safely. Incorrect delivery of liquids can bring the liquid into the lungs and not the stomach. This can cause fatal pneumonia.
- It is advisable to reduce the animals’ access to feed (especially to fresh pasture, not to water) 24 hours before administration.
