Protests are being held over Cardiff University's record of experimentation on animals for research. Information released under the Freedom of Information Act revealed more than 50,000 animals were used for research there in 2011.
He conceded that the institution would like to reduce the number of animals used, but said it would be 'some time' before scientists could rely solely on other methods of testing, as some remain 'unsophisticated and unreliable'.
Our research involving animals is aimed at the alleviation of human and veterinary disease through the advancement of medical, dental, biological and veterinary understanding.
All animal-related research work at Cardiff University is designed and carried out in accordance with the principles of the 3Rs under veterinary oversight and in compliance with the strict conditions imposed by the UK Government.
The specific research involving mice, funded by Cancer Research UK and Tenovus, was aimed at gaining new medical understanding and to help alleviate the suffering of cancer in humans.
