Biologics inspection, relevant testing and official technique setting up according to the relevant regulations are our main responsibility, and to perform the testing on biologics under laboratory control conditions. Therefore, animal facilities specific used for biologics inspection were established for years to provide the quantity of 1200 animals per month of different species, such as cattle, swine, poultry, rabbit and mice, for animal testing. As the facilities and functional equipments have been started using since 10 years ago, in order to maintain the function of facility, to keep the animal raised in a health environment for animal welfare, as well as to prevent any possible factor to influence the accuracy of the test result caused by animal raising, our project is aimed to examine and repair if necessary all the functional equipments as well as the facility itself (including the air supplier system, supervisory control apparatus and main construction).
