The number of animals used in biomedical research has reached a record low
Release date: 2015-07-21
According to the latest statistics released by the US Department of Agriculture (USDA) recently, the number of federally regulated animals used in biomedical research in the country fell to the lowest since the data was collected in 1972. In 2014, approximately 834,000 rabbits, non-human primates and other regulated animals were used for research, compared to approximately 1.5 million in the early 1970s.
Since 1993, the use of these animals has started to decline, with a 6% decline between 2013 and 2014. In 2008, USDA began posting experimental animal doses on its official website. Until now, total usage has fallen by 17%. However, this figure does not include most mice, birds and fish. These animals accounted for 98% of experimental animals but were not included in the 1966 Animal Welfare Act (AWA).
“This will be a long-term trend and there is no indication that it will slow down. In fact, it is still growing,†said Tom Holder, head of the UK’s group that supports experimental animals. Alka Chandna, a senior expert in laboratory supervision of PETA, said that animal rights protectors are "very happy."
From 2013 to 2014, the research use of animals involved in each AWA almost declined. During this time, dog use decreased by 12%, rabbits and guinea pigs decreased by 11%, and non-human primates decreased by 10%. Only an increase in the use of "all other species", including ferrets, squirrels and some rodents. From 2013 to 2014, the use of these animals increased by 25%. Cat use has increased by 4% since 2008, but it has decreased by 13% between 2013 and 2014.
A USDA spokesperson said the agency would not speculate on what led to this trend, but Holder and Chandna pointed out some factors: computer model and organizational development, animal experiment outsourcing, cost increases and logistics. Wait. In addition, public attitudes toward experimental animals have changed, and surveys show that half of Americans currently oppose the use of experimental animals. Public attitudes also prompted the government to act. The UK announced a plan last year to reduce the use of animals in research through alternatives, and urged researchers to improve the experimental process and alleviate the suffering of laboratory animals.
