Germany cuts lab animal use below two million for the first time in 2024

Germany used fewer animals in laboratory experiments in 2024 than in previous years. The total dropped below two million for the first time, reaching 1.95 million—a fall of 8.2% from 2023. Officials have linked the decline to a shift toward alternative research methods and stricter animal welfare standards.

The latest figures show that rodents made up the largest share of test subjects, accounting for 78% of the total. Mice alone represented 72%, while rats made up around 6%. Fish followed at 13%, rabbits at 4%, and birds at just 1%.

The 2024 data marks the first time Germany’s annual laboratory animal use has fallen below two million. The trend reflects a broader move toward reducing reliance on animal testing. Authorities have emphasised the need for ongoing improvements in animal welfare practices.
