Worming and parasite control

Worms can affect horses, ponies, and donkeys of all ages. Severe infestations can be life-threatening, while even low-level infections may cause:

• Gastric ulcers

• Poor nutrient absorption

• Weight loss

• Increased risk of colic

• Respiratory infections

• And even lameness – during their migrations, large strongyles larvae can injure blood vessels and cause clot formation, which may restrict blood flow and sometimes lead to subtle hindlimb lameness or weakness.

Effective worm control is essential for your equine’s health. We recommend using worm egg counts (WEC) to guide treatment. WEC testing identifies which worms are present and in what numbers, allowing targeted treatment rather than routine blanket worming. Strategic treatment also protects the environment by reducing contamination of pastures, as wormers are eliminated in faeces.

Reducing unnecessary wormer use also helps prevent resistance, which is a growing concern in equine worm populations. Good grazing management, such as daily poo picking, alongside regular WEC testing, is key to keeping your equine healthy and protecting wormer effectiveness across your yard.
