HC Deb 30 November 2001 vol 375 cc1180-1W
Mr. Breed

To ask the Secretary of State for Environment, Food and Rural Affairs how many GM animals were being used in research at the latest date for which figures are available, broken down by species; and if he will make a statement on the efficiency rates of this technique. [9598]

Angela Eagle

I have been asked to reply.

The number of scientific procedures started in the last year for which figures are available, involving genetically modified animals and showing the species and the purposes for which they were used, is given in Table 3.3 of the publication "Statistics of Scientific Procedures on Living Animals, Great Britain, 2000", a copy of which is in the Library. The number of animals used is close to the number of procedures, as animals are not normally re-used.

Questions about the science involved are primarily for the Minister of Science and Innovation at the Department of Trade and Industry. However, I understand a range of techniques are used, depending on the required type of modification, to produce new lines of genetically modified animals. The efficiency of the techniques ranges broadly from 1 per cent. to 30 per cent. (that is, the number of successfully genetically modified offspring as a percentage of the number of germ cells or embryos manipulated).

The offspring of established genetically modified lines are also reported in the Home Office/National Statistics annual publication mentioned. About 35 per cent. of such offspring are used in research programmes, the remainder being used for further breeding only.
