Experiments on animals are in principle subject to authorisation. If you want to carry out animal tests, you must apply to the LAVG. Certain tests which only need to be displayed are excluded from the authorisation requirement. As the applicant, first ask the LAVG whether your project on animals is an attempt under animal welfare law and whether its authorisation must be applied for or whether the notification of the experimental project is sufficient. In any case, animal testing may only be carried out for one of the purposes specified in the Animal Welfare Act. The approval/processing of animal experiments and the examination of the expertise of the investigators is the responsibility of the LAVG. The districts and county-free cities are responsible for granting permission and monitoring of experimental livestock holdings. The bodies carrying out tests must appoint a person responsible for animal welfare. The applications, but also the clarification of questions of animal husbandry, also the examination of the expertise should be made via you as a person responsible for animal welfare. Permitted purposes under the Animal Welfare Act, the indispensability of which you must prove, are basic research Preventing, detecting or treating diseases, suffering, bodily harm or physical ailments Recognition/influence physiological conditions of humans and animals Identification of environmental hazards, Testing of substances or products Development/testing of medicinal products, medical devices, chemicals or other substances and products species conservation Note 1: The LAVG has 40 working days to decide on the application. The period begins after formal completeness. The Animal Experiments Commission, which has to cast its vote within the time limit, supports the LAVG, but does not take the approval decision. Seasonal experiments (wild animals) should be planned in good time; in case of doubt, application before project approval applies. Note 2: Advertisements are not simply "taken note" by the LAVG, but, like the applications from the LAVG, are examined extensively, without the involvement of the Animal Experiments Commission. The trial must not be started before the expiry of 20 working days after receipt by the LAVG. Note 3: Records of animal testing must be carried out in accordance with Section 9 TierSchG in conjunction with Section 29 TierSchVersV and to present it at the request of the LAVG. Note 4: As an animal welfare officer, you must in principle be a veterinarian, of which the LAVG can approve exceptions. In addition to the requirements of Section 5 TierSchVersV, it is advantageous from the point of view of the authorities if you have scientific expert and animal species-specific experience and with regard to the formal application. Note 5: Adjacent right must be taken into account by you as the applicant. This is part of the ancillary provisions of the animal welfare permit.
