Royal Veterinary College leads humane equid slaughter guidance

By Daniel Okafor

About 5 million horses and 6 million donkeys are slaughtered worldwide each year, primarily for meat and by-products. The Royal Veterinary College, World Horse Welfare and the Humane Slaughter Association have developed new guidance for horses, mules and donkeys before and during slaughter.

What did the four-country assessment examine?

The evidence base came from assessments of equine welfare before and during slaughter in the UK, Italy, Mexico and Ghana. Researchers examined behavior, brainstem reflexes, electroencephalography and pathology in different contexts. The report does not state sample size or species-specific enrollment counts.

Dr. Kate Fletcher led the project through her RVC PhD, which World Horse Welfare funded. Professor Troy Gibson, the RVC’s Professor of Animal Welfare Science, served as principal investigator. Fletcher is also Technical Lead at the Humane Slaughter Association.

Research on how different slaughter practices affect equid welfare had been limited. Before this work, guidance drew largely on experience and studies from other species. Those studies did not reflect equid behavioral and physiological needs.

A high proportion of equid slaughter occurs in low- and middle-income countries. Restricted resources and lack of legislation in some settings can compound welfare risks.

Takeaway: The recommendations now rest on direct equid research rather than assumptions drawn from other species.

What minimum standards do the guidelines set?

• Handle equids calmly and in a species-appropriate manner. Train staff to recognize stress, including the subtler behavioral responses shown by donkeys.
• Keep flooring clean, dry and non-slip. Keep walkways clear and unobstructed.
• Keep pair-bonded animals together. Keep foals with their mothers where space allows, which helps reduce distress.
• Make stunning before slaughter standard in every setting. Use a correctly positioned penetrating captive-bolt device or another method that ensures an immediate, humane death. Provide additional support for resource-restricted settings where alternatives are not yet available.
• Monitor every stage after stunning with trained staff who can recognize and act on signs of ineffective stunning. Begin bleeding promptly, within a maximum of 50 seconds, to reduce the risk of an animal regaining consciousness.

Takeaway: Calm handling, suitable surfaces, reliable stunning and rapid bleeding form the core minimum standard.

What changes for practice and policy?

Professor Gibson said millions of equids are slaughtered each year while detailed guidance based on empirical welfare research remains limited. He said the partnership combines scientific evidence with practical recommendations for reducing suffering in the UK and internationally.

Dr. Fletcher said: “We hope that these guidelines will advance international standards, policy, and legislation relating to equid slaughter, by offering scientific, species-specific, practical recommendations.” She described the work as a comprehensive evidence base for sustainable, pragmatic improvements.

World Horse Welfare Chief Executive Dr. Roly Owers said: “If they are to be slaughtered, it should be done humanely with consideration for their species-specific needs.” He said the charity’s century of work in Europe had improved conditions but left critical evidence gaps for global policy and practice.

This is guidance, not enacted regulation. The report identifies no new FDA CVM, EMA or USDA requirements, and the guidelines do not replace UK or international law. Industry professionals, welfare organizations and policymakers can use the document as reference standards.

At slaughter facilities, adoption means training staff to spot stress and ineffective stunning, maintaining safe flooring and using correctly positioned equipment. Every animal requires post-stunning monitoring, with bleeding starting no later than 50 seconds. The recommendations also recognize the infrastructure constraints faced in resource-limited settings.

Takeaway: The immediate practice change is a defined, species-specific sequence from handling through bleeding.

Which sector does this guidance affect?

• Companion animals: The document makes no recommendations for companion-animal euthanasia or end-of-life veterinary care. Its scope is equids presented for slaughter.
• Food animals: This is the primary sector addressed. Relevant measures cover handling, flooring, grouping, stunning, staff monitoring and bleeding time at slaughter.
• Public health: The report gives no microbiological, zoonotic-disease or food-safety results. The Humane Slaughter Association has a broader remit that includes killing for welfare reasons and disease control, but the equid assessment reports no results in those areas.

Takeaway: The evidence supports slaughter-welfare improvements, not claims about companion care or public-health risk.

Who produced the guidance?

The Royal Veterinary College describes itself as the UK’s largest and longest-established independent veterinary school and a Member Institution of the University of London. It is one of the few veterinary schools with RCVS accreditation in the UK, associated recognition from AVBC for Australasia, VCI for Ireland and SAVC for South Africa, EAEVE accreditation in the EU, and AVMA accreditation in the US and Canada.

QS World University Rankings by subject 2026 places the RVC first among veterinary schools worldwide. The research-led college offers undergraduate and postgraduate programs in veterinary medicine, veterinary nursing and biological sciences.

The 2021 Research Excellence Framework rated 88% of RVC research internationally excellent or world class. Teaching hospitals and first opinion practices in London and Hertfordshire give animal owners and veterinary professionals access to expert care and advice.

World Horse Welfare is registered charity no. 206658 and SC038384. The organization has worked for almost 100 years to place the horse at the center of care and welfare in the UK and worldwide.

The Humane Slaughter Association is independent registered charity no. 1159690 and the UK’s only charity concerned exclusively with humane treatment of food animals worldwide. Its remit covers cattle, sheep, pigs, poultry, fish, deer and equids in markets, during transport, at slaughter, and when animals are killed for welfare reasons or disease control.

HSA works through research, education, training and technical advances to produce practical, lasting improvements in food-animal welfare.

Takeaway: Three established organizations produced guidance intended for operators, veterinary professionals, welfare groups and policymakers worldwide.
