Question 1

Which metric is considered the gold standard for assessing long-term HPA axis activation as a measure of chronic stress in livestock?

Accepted Answer

Fecal glucocorticoid metabolite concentration

Answer

Fecal glucocorticoid metabolites integrate adrenal output over time, are non-invasively collected, and avoid the acute stress artifact of venipuncture, making them the preferred chronic stress biomarker.

Question 2

The IACUC (Institutional Animal Care and Use Committee) is required by US regulations to include which member category?

Accepted Answer

At least one non-affiliated community member unrelated to the institution

Answer

Federal regulations require IACUC membership to include at least one veterinarian, one scientist, one non-scientist, and one person unaffiliated with the institution to ensure community perspective.

Question 3

In a cat colony, which behavioral sign most clearly indicates that a subordinate individual is experiencing chronic social stress?

Accepted Answer

Consistently avoiding food stations and hiding when dominant cats are present

Answer

Chronic avoidance of resources and concealment from conspecifics indicates sustained fear and inability to compete, reflecting compromised welfare in multi-cat households or colonies.

Question 4

Which type of handling technique has been shown to most effectively reduce fear responses during veterinary examination in cats?

Accepted Answer

Low-stress handling using minimal restraint and a cat-friendly environment

Answer

Low-stress handling protocols that use the minimal effective restraint, feline pheromones, and cat-friendly waiting areas significantly reduce cortisol and fearful behavior during examination.

Question 5

Nesting behavior in sows is most compromised by which housing system?

Accepted Answer

Gestation crates that prevent movement and turning

Answer

Gestation crates prevent the sow from performing motivated pre-farrowing nesting movements, causing chronic frustration and representing a major animal welfare concern.
