ANSI 1124 Introduction to the Animal Sciences Practice Exam

Changes in behavior or feeding patterns are indeed a common indicator of stress in animals. When an animal experiences stress, it often exhibits alterations in its usual behaviors. For instance, an animal may become more aggressive, withdrawn, or lethargic, or it may exhibit repetitive movements or vocalizations. Additionally, stress can lead to changes in feeding habits, such as reduced appetite or altered eating schedules. These behavioral changes can serve as critical signals for caregivers or researchers to identify and mitigate sources of stress in the animal's environment, thereby promoting better welfare and health outcomes.

In contrast, increased energy levels typically suggest that an animal is not under stress but rather in a state of excitement or engagement. Improved breeding success and higher weight gain are generally indicators of good health and optimal living conditions, which are unlikely to occur in a stressed animal. Understanding these behavioral indicators is crucial for animal management and welfare practices.
