MBR Acres
MBR Acres, based in Cambridgeshire, breeds over 2,000 beagles per year for UK and European laboratories. Asserted to be a subsidiary of Marshall BioResources, the facility has been the target of Camp Beagle — the longest-lasting animal rights protest camp in the UK — since June 2021. Puppies are shipped at approximately 16 weeks of age.
Overview
MBR Acres operates a beagle breeding facility in Cambridgeshire, England. The facility breeds more than 2,000 beagles per year, supplying laboratories across the United Kingdom and Europe. Puppies are typically shipped to research facilities at approximately 16 weeks of age.
Ownership
MBR Acres is widely asserted to be a subsidiary of Marshall BioResources, the dominant global supplier of purpose-bred beagles. The ownership linkage is consistent with Marshall's known operational structure, though direct evidence in publicly available filings is limited. Companies House records establish MBR Acres Ltd as a registered entity but do not fully map the corporate chain in a way that conclusively demonstrates the Marshall connection through public documents alone.
Operations
The facility functions as a breeding and early-life supply node in the beagle trade. Dogs are bred on-site, raised through weaning and early socialization, and then transported to laboratories for use in research. The 16-week shipping age aligns with standard industry practice for delivering dogs at an age suitable for regulatory toxicology studies, which typically require animals between four and six months old at study start.
Camp Beagle
Since June 2021, the facility has been the site of Camp Beagle — a sustained protest encampment that has become the longest-lasting animal rights protest camp in the United Kingdom. Protesters maintain a continuous presence outside the facility, documenting transport vehicles and raising public awareness of the site's purpose.
The protest has generated significant media coverage and public engagement. It has also prompted legal responses, including injunctions against protesters and police actions at the camp.
UK Regulatory Context
MBR Acres operates under the UK's Animals (Scientific Procedures) Act 1986 (ASPA), administered by the Home Office. The UK publishes more granular data on animal use in research than most countries, though breed-level reporting is limited. UK statistics for 2024 recorded 2,646 procedures involving dogs. The relationship between breeding supply and procedure counts is not straightforward — not all bred animals enter studies, and some studies involve multiple procedures per animal.
Significance
MBR Acres represents the UK node of the international beagle trade. It demonstrates that purpose-bred beagle supply chains operate across regulatory jurisdictions, with breeding occurring under one country's rules and research under another's.
