Assistant Laboratory Animal Technician (ALAT) Practice Exam

What does environmental enrichment provide for laboratory animals?

1. Caloric surplus for rapid growth

2. Opportunity for variety and species-specific behaviors

3. Familiarity with human handling

4. Reduction of social interaction

The correct answer is: Opportunity for variety and species-specific behaviors

Environmental enrichment is crucial for the well-being of laboratory animals as it provides them with opportunities to engage in species-specific behaviors and offer variety in their daily activities. By allowing animals to express natural behaviors—such as foraging, nesting, or exploring—enrichment contributes to their physical and psychological health. This is particularly important in laboratory settings where animals may experience stress due to confinement and limited stimulation. Enhancing the environment can involve adding structures for climbing, providing different substrates, or incorporating toys that encourage manipulation and play. Such activities not only improve the overall quality of life for the animals but also can lead to more consistent and reliable research outcomes, as well-adjusted animals tend to exhibit more normal physiological and behavioral responses. While the other options may seem relevant in specific contexts, they do not capture the primary role of environmental enrichment as effectively. For instance, while social interaction can be an important factor in animal welfare, reduction of social interaction does not align with the benefits of enrichment, which typically encourages positive social behaviors.
