April 24th of each year is World Experimental Animal Day. Experimental animals are the first of the "four major elements" in life sciences, especially in drug research, and are the "substitutes" for humans. They are known as "living precision instruments and living reagents" and play an irreplaceable role. As pharmaceutical scientists, our scientific research directly or indirectly carries the dedication and dedication of experimental animals. They "live to the death", fighting at the forefront of scientific research, dedicating themselves to life sciences and the creation of new drugs. These little creatures deserve our respect. Respecting them means respecting ourselves and rigorous science.

Tiancheng established the "Management Committee for the Use of Experimental Animals" in 2011, actively introducing and studying the most advanced international animal use and management concepts. All animal facilities, experimental projects using animals of all types, and all scientific researchers were included in a management system that meets international standards. In 2013, it passed the international AAALAC certification for the first time and successfully passed re certification in 2015, 2018, and 2021, The operating system has received high praise from internationally certified experts.

Tiancheng Evaluation regularly holds commemorative activities to thank experimental animals for their great contributions to scientific research. We always remind everyone to respect animals and respect life!

The Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC) was established in 1965 as a non-profit organization that promotes the humane treatment of animals in the scientific field through voluntary certification programs, program status assessment services, and educational programs. AAALAC certification not only enhances the level of animal husbandry management and the effectiveness of scientific achievements, but also emphasizes the treatment of experimental animals based on animal welfare principles and ensures the accuracy of animal based scientific research data. Experimental animals must be free from hunger, fear, and a suitable living environment and diet in order to unleash their natural instincts and exhibit their natural physiological and mental states. Therefore, the experimental data collected from them can be truthful and objective. The US Food and Drug Administration (FDA) and the European Medicines Administration (EMA) strongly recommend conducting animal experiments related to new drug development in AAALAC certified laboratories.
