National Taiwan University established the "Laboratory Animal Resource Center (ARC)" in 2014 to provide a high quality of animal care for biomedical research. The ARC emphasizes humane care for experimental animals to meet the international animal welfare standards and start providing services since June 2016. So far, we have setups for mice, rats, rabbits, chickens and pigs. In the future, we will not only increase instruments to accommodate more animals, but also provide services such as embryo frozen, clean, to boost the research quality. Therefore, our mission is to provide the best animal caring service which meets the animal welfare standard to ensure the repeatability of animal experiments.
