Assistant Laboratory Animal Technician (ALAT) Practice Exam

How often should soiled bedding be removed and replaced?

1. Once a week

2. As often as necessary to keep animals clean

3. Every other day

4. Once a month

The correct answer is: As often as necessary to keep animals clean

Soiled bedding should be removed and replaced as often as necessary to keep animals clean because the primary goal of maintaining good animal husbandry practices is to ensure the health and welfare of the animals. Regular removal of soiled bedding prevents the buildup of waste material, which can lead to increased ammonia levels, promote the growth of pathogens, and cause undue stress to the animals. The frequency of bedding changes will vary based on factors such as the species of the animal, the type of bedding used, the number of animals in the enclosure, and their specific needs. For example, some animals may produce more waste than others, necessitating more frequent changes, while specific species might require a particular environment to thrive. Therefore, a flexible approach that prioritizes the cleanliness and comfort of the animals is crucial rather than adhering to a fixed schedule like once a week or once a month. Proper observation and assessment of the animals and their living conditions will guide the frequency of bedding replacement.
