Protecting Flocks and Profits: The Vital Role of HISHA in EAE Prevention

When it comes to sheep farming in the Highlands and Islands, flock health is important. That’s why the Highlands and Islands Sheep Health Association (HISHA) plays such a vital role—providing farmers with EAE-accredited sheep to ensure they can buy top-quality, disease-free replacements with confidence.

What is EAE and Why Does it Matter?

Enzootic Abortion of Ewes (EAE) is the leading cause of abortion in sheep, and its impact on farm profitability is severe. EAE can trigger devastating “abortion storms” and widespread lamb loss, often without any warning signs.

The disease is extremely difficult to control. A flock can become infected through apparently healthy replacement ewes. Once infected, these animals may abort the following spring—either a few weeks before lambing begins or by delivering weak, non-viable lambs. While these ewes may go on to lamb normally in future years, they remain carriers of the disease, posing a risk to their own lambs and the wider flock.

The cost? At least £95 per ewe. EAE costs the UK sheep industry up to £20 million a year

The risk? Long-term infection and transmission.

The danger? EAE is also a human health hazard, especially for pregnant women.

 Why Choose HISHA EAE-Accredited Replacements?

HISHA gives farmers peace of mind by offering rigorously tested and accredited stock. Here’s what sets HISHA apart:

• Annual Screening: All HISHA flocks are tested for EAE every year.
• Post-Lambing Testing: Sheep are tested within three months after lambing.
• Strict Biosecurity: Members follow robust protocols to prevent disease spread.
• Vaccination-Ready: HISHA sheep are clean breeding replacements that can be vaccinated for added protection.

By sourcing HISHA-accredited replacements, farmers can protect their flocks, safeguard their profits, and reduce the risk of EAE outbreaks.
