Manure research in horses -schedules

It is important to carry out manure research regularly (4 times a year). This helps you build a clear record, giving valuable insight into your horse's worm sensitivity. It also serves as an effective check on your worm management strategy.

We recommend deworming once preventively at the end of December or the beginning of January. Whether this is necessary depends on various factors such as age, living conditions, and previous results. At the end of the year, you will receive personalized advice from us on whether preventive deworming is appropriate for your horse(s).

Every year, adorable foals are born, and of course, you want to take the best possible care of them. But how do you manage worm control for a mare and her foal?
Foals are vulnerable, so it's important to perform manure research regularly. This allows you to monitor the worm cycle closely. With us, you build a clear record, and based on that data, we can provide tailored advice on whether preventive deworming is appropriate. You can follow this schedule if your mare and foal are healthy and your hygiene management is optimal. If you have concerns about your foal's health, we always recommend contacting your own veterinarian.

Below you will find a schedule of all active ingredients available for treating gastrointestinal worms in horses. We are seeing an increase in resistant worms, which is why it is very important to conduct manure research before deworming.

All gastrointestinal worms have their own cycle, but the basic process is the same. The larva is ingested by the horse and migrates through the body. Inside the body, it develops into a worm that lays eggs. The eggs are excreted through the manure onto the pasture. From the eggs, new larvae emerge, and the cycle starts over again. Removing manure from the pasture is therefore essential to prevent (re)infection.

The larvae of the redworm have the unique ability to encyst themselves. While the larvae are encysted, any adult worms present may still lay eggs. That’s why it’s important to perform manure research throughout the entire year.

Horses up to the age of 2 are more likely to contract a roundworm infection. After that, they gradually develop natural resistance. That’s why roundworm infections are rarely seen in older horses.

Below you’ll find the cycle of the liver fluke. In recent years, liver fluke infections have become increasingly common. What makes this parasite unique is that its larvae require an intermediate host—the mud snail—to reproduce.

Below you’ll find the cycle of habronemiasis. This disease used to be rare in the Netherlands, but in recent years it has become increasingly common in horses.
