Maintenance of colonies of established genetically altered animals, not used in other procedures

This contains the number of animals required for the maintenance of colonies of genetically altered animals of established lines with an intended harmful phenotype and which have exhibited pain, suffering, distress or lasting harm as a consequence of the harmful genotype. The intended purpose for which the line is being bred for is not recorded.

This excludes all animals needed for the creation of a new genetically altered line and those used in other procedures (other than creation/breeding).
