However, scientists are obliged to replace animal experiments with alternatives as far as possible and to work towards the development of further alternative methods. Veterinarians, animal carers and researchers are constantly working to improve animal welfare both in experiments and in husbandry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The 3R principles<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientists at the DRFZ are very aware of their responsibility towards animals and always apply the 3R principle to experiments in order to reduce the stress on animals.. The 3Rs stand for \u2018Replace, Reduce, Refine\u2019. In practical terms, this means researchers at the DRFZ attempt to carry out as many experiments as possible without the use of animals (\u2018Reduce &amp; Replace\u2019), for example by using cell cultures. When carrying out animal experiments, care is taken to use a statistically calculated minimum group size of animals, with no more animals used than necessary (\u2018Reduce\u2019). Moreover, due to the availability of more and more sophisticated technology,&nbsp; many non-invasive examination methods are available (\u2018Refine\u2019), which reduce animal suffering and allow data to be generated from just a few animals (\u2018Reduce\u2019).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientists are advised in their work by independent animal welfare officers, who also ensure and monitor the welfare of the animals and compliance with all guidelines and regulations. The Animal Welfare Committee, which meets regularly, supports the animal welfare officers in their work and in monitoring animal welfare.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Today, the 3Rs principle is the basis for animal welfare policy and practice and practice of modern research approaches in many countries.<\/strong>This animated film explains the 3R principle and describes how it is implement-ed in research.<br>(Source: https:\/\/www.tierversuche-verstehen.de\/filme\/)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Alternative methods<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the Animal Welfare Law, animal experiments may only be carried out if no animal-free methods are available (Animal Welfare Law \u00a7 7a Para. 2 No. 2). Animal experiments are still the only way to find out which circumstances cause the immune system to react against the body.<\/p>\n\n\n\n  <section id=\"block_cee920e3df8b1e701d4e4953e7df98e6\"\n           class=\"section accordion  alignwide \"\n           data-open=\"multiple\">\n    <div class=\"container container--center container--medium\">\n      \n      \n      \n              <div id=\"panel-\"\n             class=\"accordion__category active\" role=\"tabpanel\"\n             aria-labelledby=\"tab-\">\n                    <script type=\"application\/ld+json\">\n            {\n              \"@context\": \"https:\/\/schema.org\",\n              \"@type\": \"FAQPage\",\n              \"mainEntity\": [{\"@type\": \"Question\",\"name\": \"Many alternative methods to animal testing are already in use.

For example, Dr Timo Gaber, from the Buttgereit research group, is working together with Dr Alexandra Damerau and Dr Moritz Pfeiffenberger on the development of vitro 3D models that simulate inflamed joints.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.drfz.de\/en\/arbeitsgruppen\/glukokortikoide-bioenergetik\/\" target=\"_blank\" rel=\"noreferrer noopener\">More about research into in vitro models at the DRFZ<\/a><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><strong>Handling &amp; Habituation<\/strong><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">From birth, mice are habituated to handling using gentle methods. One of the methods used for this is tunnel handling. For this purpose, there is a transparent tunnel in the cage, which serves as a hiding place for the mice and represents a familiar environment. The animal can be taken out of the cage via the tunnel to carry out a health check, for example. Several studies have shown that this type of handling is significantly less stressful for the animals than lifting them by the tail. It has also been shown that working with less stressful animals has a positive effect on scientific results and that the data obtained is more reliable and reproducible.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"799\" height=\"506\" src=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867.jpg\" alt=\"\" class=\"wp-image-981\" srcset=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867.jpg 799w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867-300x190.jpg 300w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867-768x486.jpg 768w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867-550x348.jpg 550w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/090c62ae04395bf223986cbae7a30867-150x95.jpg 150w\" sizes=\"auto, (max-width: 799px) 100vw, 799px\" \/><figcaption class=\"wp-element-caption\">Fig.: A mouse is moved with a tunnel.
