In the hot and humid climate of the tropics, keeping horses healthy can be a challenge. This is especially true when it comes to dealing with nasty little worms called gastrointestinal nematodes. These parasites can cause big problems for horses, but a recent study showed that a smart approach can help keep them in check. The study took place over two years in the town of Anastácio, in the state of Mato Grosso do Sul, Brazil. The goal was to find a way to reduce the number of these worms in both the horses and their environment, without causing any harm to the horses or making the worms resistant to treatment.

        The study involved two groups of horses: one group received special treatment, and the other did not. The treated group was given a medicine called ivermectin twice a year, in May and September. Every four weeks, scientists collected samples of horse poop, weighed the horses, checked their body condition, and counted the number of worm eggs and larvae in the pasture. They also used a special test to identify a particularly nasty worm called Strongylus vulgaris.

        The results were promising. The treatment worked to reduce the number of worm eggs in the horse poop and also helped to keep the number of larvae in the pasture down. It also provided protection against the nasty Strongylus vulgaris worm. The treatment did not affect the horses' weight or body condition, which is a good sign. The most common type of worm found was Cyathostominae.

        The study showed that using this strategic approach with just two treatments a year can be effective. It can reduce the number of worm eggs and larvae in the pasture, and keep the horses healthy. This is important because it means that horses can stay healthy without being over-treated with medicine, which can sometimes make the worms resistant to treatment.

        The study also found that during the dry season, there was a big difference between the treated and untreated groups in the number of larvae in the pasture. This suggests that the treatment was most effective during this time. The study also showed that the treatment did not affect the horses' health indicators, such as weight and body condition score.

        It's important to note that this study was the first of its kind in a tropical region. This means that the findings could be useful for other horse owners in similar climates. The study also highlights the importance of using a strategic approach to worm control, rather than just treating horses whenever worms are found.

        The study also raises some interesting questions. For example, why was the treatment most effective during the dry season? And what other factors might affect the effectiveness of the treatment? These are questions that future research could explore.

        The study also highlights the importance of using a strategic approach to worm control, rather than just treating horses whenever worms are found. This is because over-treating horses with medicine can sometimes make the worms resistant to treatment. By using a strategic approach, horse owners can help to keep their horses healthy without putting them at risk.

        The study also shows that it's possible to keep horses healthy in the tropics, even with the challenges posed by gastrointestinal nematodes. This is good news for horse owners in tropical regions, as it means that they can keep their horses healthy without having to worry about over-treating them with medicine.
