Environmental conditions and care of the animals

The environmental conditions of the animal facilities are monitored daily. The temperature and humidity are measured every day and air-conditioning is monitored continuously.

Cages and pens

Small rodents and rabbits are usually held in cages and large laboratory animals in pens with a solid floor. The minimum requirements for the area per one animal or group of animals are set in the legislation.

At KEKS, mice and rats live in solid bottom plastic cages with a layer of bedding on the bottom. Rabbits are housed in cages with a perforated plastic floor and a litter sheet beneath the floor. During workdays, rabbits are transferred to more spacious floor pens where they can get exercise. Pigs are kept in floor pens with a shelter-box. Sheep are kept either in smaller pens as pairs or in a combined fold as a flock.

An integral part of the animal well-being programme at KEKS is that the animals are offered spaces which clearly exceed the minimum requirements.
