Art. 9 Approved methods for producing genetically modified animals
(Art. 142 para. 4 AniWO) 1 The approved methods for producing genetically modified animals are listed in Annex 1. 2 A method may be approved if it is in widespread practical use and best ensures the well-being of the animals compared with other methods. Both the implementation of the procedures and measures and the success rate and number of surplus animals must be taken into account. 3 The approved methods shall be used in accordance with a standard protocol in a manner that best ensures the well-being of the animals. 4 The laboratory animal facility shall keep a record of the success rate in the use of the approved methods for the attention of the cantonal authorities. If the success rate is unsatisfactory, the laboratory animal facility must take action to improve it.
Art. 10 Genotyping
(Art. 120 para. 1 and 123 AniWO) 1 The following methods and combinations thereof are approved for genotyping in production and breeding of genetically modified animals: a. non-invasive methods such as the investigation of faeces or saliva; b. methods combined with the marking of animals; c. blood sampling. 2 Tail biopsies are only permitted in particular cases justified by the experiment in question. Not more than 5 mm of the tail may be removed. 3 In small rodents the following methods for combined genotyping and marking are permitted: a. amputation of the distal phalanx of a toe in the first nine days after birth; not more than two toe tips per animal may be amputated; b. identification by means of ear perforation or notching after weaning.

Art. 11 Phenotyping
(Art. 124 AniWO) In the production and breeding of animal lines or strains, the killing of animals for anatomical or pathological purposes and investigations such as behavioural studies with mild strain or blood sampling are permitted provided they serve to characterise the animal lines and strains. The studies shall be performed in a manner that best ensures the well-being of the animals.
