As spring approaches, it is time to start thinking about parasite management.

Parasites are a complicated topic that often gets oversimplified when searching for information. A holistic approach always considers the intestinal immunity of each horse, as that varies from horse to horse. However, parasite management tends to become more complex in herd environments where group dynamics play a role.

The Impact of Parasites on Horse Health

Parasites can have widespread effects on a horse’s body. They contribute to inflammation, disrupt the nervous system, and place stress on multiple organs. Horses with allergies are particularly susceptible because their immune systems are overactive, making it harder to manage infections. If a calm horse suddenly becomes anxious or unmanageable, parasites could be a hidden factor.

Parasites and Ulcers

When horses struggle with digestive issues, an unresolved parasite infection can complicate their recovery. So, it is essential to address parasites first, as parasites, especially encysted strongyles, damage the intestinal lining, which could exacerbate or trigger ulcers.

The Importance of Early and Proper Treatment

Promptly addressing parasites is essential for preventing long-term health damage to your horse. Horses with allergies or ulcers are particularly vulnerable, as parasites tend to exacerbate their symptoms. Parasite treatments should be specific to the condition of each horse. It is also essential to consider the possible effects of parasite die-off with older or weaker horses, and veterinary guidance may be needed.

The Effectiveness of Herbal Treatments

While herbs have some anti-parasitic properties, they cannot be relied on to eliminate a significant infestation, as fecal testing has shown that herbal remedies alone do not effectively reduce parasite counts. Chemical dewormers are the most effective option for controlling parasites, especially in high-load cases.

Managing Parasite Resistance

Overuse and improper use of dewormers can cause parasite resistance, making it harder to eliminate infections. Even when treated, some horses still carry high parasite loads, and parasites can mutate to withstand certain chemicals. Rotating dewormers and strategically targeting different life stages of parasites are essential strategies for long-term parasite management.

Key Takeaways for Responsible Parasite Control

A strategic, science-based approach to parasite management is crucial. Regular fecal egg counts can help track parasite levels, and a well-planned deworming schedule prevents resistance from developing. Supporting the microbiome with good nutrition will also help in building overall resilience against infections.
