Abstract

The use of animals for scientific research has been justified since the beginnings of civilization, when they were considered as a biological reagent and only served to meet the needs of humans. This concept changed when ethical considerations towards their use as experimental beings began to have greater relevance. The birth of animal welfare has impacted the entire scientific community and all animal users, allowing a greater understanding of the needs and behavior of different species. From this redefinition of the animal as a biological reagent a new object of study arises: the relationship of the animal with its environment and its attempts to cope with the demands of the environment. Several attempts have been made to enrich the environment of experimental animals in order to improve their welfare but often in a poorly studied
manner, and this has produced erroneous scientific results. Therefore, it is imperative to work with specific indicators of wellbeing that diagnose and remedy poor welfare conditions, and accurately communicate the conditions of the groups from which the statements are made. Thus, animals provided to researchers should be accompanied with certifications about strain, breeding conditions, type of enrichment and animal welfare indicators, prior to their use. In the future, animal welfare should not only be on the ethical note of experimental studies, but also be an indisputable part in the methodological section.
