BCSE Animal Welfare and Behavior 5 — Questions and Answers
Question 1: Which metric is considered the gold standard for assessing long-term HPA axis activation as a measure of chronic stress in livestock?
- Fecal glucocorticoid metabolite concentration (Correct answer)
- Single serum cortisol sample
- Heart rate variability alone
- Behavioral observation score alone
Correct answer: Fecal glucocorticoid metabolite concentration
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?
- At least one non-affiliated community member unrelated to the institution (Correct answer)
- A licensed pharmacist
- A biostatistician
- A representative from the state veterinary licensing board
Correct answer: At least one non-affiliated community member unrelated to the institution
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?
- Consistently avoiding food stations and hiding when dominant cats are present (Correct answer)
- Occasional hissing during play
- Normal elimination in the litter box
- Grooming in an open area
Correct answer: Consistently avoiding food stations and hiding when dominant cats are present
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?
- Low-stress handling using minimal restraint and a cat-friendly environment (Correct answer)
- Firm scruffing to immobilize the cat quickly
- Chemical restraint for all examinations
- Towel wrapping with maximum tension
Correct answer: Low-stress handling using minimal restraint and a cat-friendly environment
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?
- Gestation crates that prevent movement and turning (Correct answer)
- Group housing with straw bedding
- Deep-litter outdoor systems
- Hoop-barn group housing
Correct answer: Gestation crates that prevent movement and turning
Gestation crates prevent the sow from performing motivated pre-farrowing nesting movements, causing chronic frustration and representing a major animal welfare concern.
Question 6: When performing a welfare assessment using the Welfare Quality protocol for cattle, observers score animals on how many principles?
- Four principles: good feeding, good housing, good health, and appropriate behavior (Correct answer)
- Three principles: health, behavior, and environment
- Five principles including reproductive performance
- Two principles: physical and psychological welfare
Correct answer: Four principles: good feeding, good housing, good health, and appropriate behavior
The Welfare Quality protocol organizes cattle welfare into four principles (feeding, housing, health, behavior), each containing multiple measurable criteria scored at the animal level.
Question 7: Which behavioral sign in a laboratory fish species most reliably indicates an analgesic need following a painful procedure?
- Reduced swimming activity, loss of shoaling behavior, and rubbing of the affected area (Correct answer)
- Increased appetite immediately post-procedure
- Brighter coloration
- Increased surface breathing only
Correct answer: Reduced swimming activity, loss of shoaling behavior, and rubbing of the affected area
Hypoactivity, social withdrawal from the shoal, and protective guarding or rubbing of an injured area are the most validated pain-indicative behaviors in teleost fish.
