title: [The using of hollow bricks as a shelter for adaptation of wild rodents' colonies in captivity].
abstract: Difficulties for adaptation of wild rodents' colonies in the laboratory may hamper experimental studies. We describe the use of a hollow brick inside cages, to provide shelter and reduce stress of the animals. It facilitates the cleaning of cages, since the animals stay inside the brick while they are transferred to a new cage. This method was applied in a trial for adaptation of Oryzomys nigripes in captivity. Despite transportation for more than 1500 km, mortality was zero in the group of 62 rodents and the colony expanded immediately. A hollow brick is a cheap and widespread available material for improving adaptation of wild rodents to captivity.
