1 · Behavioural signs of stress · hard

A welfare study finds high plasma cortisol in boars sampled immediately after mating. What is the most important caution in interpreting this?

  1. Cortisol also rises with positive arousal, so it does not prove a negative state
  2. Cortisol is not secreted by pigs, so the assay must have cross-reacted
  3. A single high cortisol value proves chronic distress in all of the sampled boars
  4. Cortisol falls during arousal, so the result must reflect a sampling error
Answer and working

A. Cortisol also rises with positive arousal, so it does not prove a negative state

Glucocorticoids rise with arousal of either valence, including mating and play, and with the act of sampling. Reading one high value as distress is the classic error; behaviour and other measures must be read together. Pigs do secrete cortisol.

2 · Behavioural signs of stress · hard

A Thoroughbred yearling that was weaned abruptly and is now stabled on a high-concentrate, low-forage diet begins crib-biting. The owner wants to fit a cribbing collar. What is the best advice?

  1. Fit the collar at once, because crib-biting always damages the stomach lining and teeth
  2. Fit the collar and add more concentrate, because the horse is short of energy
  3. Isolate the horse so other horses do not learn crib-biting by imitation
  4. Address the causes with more forage, turnout and company rather than only prevent it
Answer and working

D. Address the causes with more forage, turnout and company rather than only prevent it

Crib-biting is linked to low-forage, high-concentrate diets, abrupt weaning and limited social contact. Physically preventing it without addressing the cause may increase frustration. More concentrate worsens the cause, and isolation removes social contact; evidence for copying is weak.

3 · The Five Freedoms and the Five Domains · easy

Which provision corresponds to the freedom from discomfort?

  1. Ready access to fresh water and a balanced diet to maintain full health and vigour
  2. An appropriate environment including shelter and a comfortable resting area
  3. Prevention or rapid diagnosis and treatment of disease and injury
  4. Sufficient space, proper facilities and company of the animal's own kind
Answer and working

B. An appropriate environment including shelter and a comfortable resting area

Each freedom has a provision. Discomfort is prevented by shelter and a comfortable resting area. Water and diet answer hunger and thirst; prevention and treatment answer pain, injury or disease; space and company answer normal behaviour.

4 · Welfare assessment · medium

Why does WOAH favour animal-based criteria when welfare standards are compared?

  1. Because resource-based measures cannot legally be audited by an independent third-party inspector
  2. Because animal-based measures are usually quicker and cheaper to record
  3. Because the same resources can produce different welfare outcomes on different farms
  4. Because resource-based measures are banned under international trade rules
Answer and working

C. Because the same resources can produce different welfare outcomes on different farms

Outcomes on the animal reflect the result of resources and management together, which vary between farms. Animal-based measures usually take more skill and time, not less, and resource measures are easy to audit.

5 · Welfare in transport · hard

A beef cow with a gestation length of 283 days is due to be unloaded after a long journey on day 262 of pregnancy. Is she fit to travel under the WOAH final-10% rule?

  1. Yes; the final 10% starts at about day 270, so she is outside it
  2. No; the final 10% starts at about day 255, so she is within it
  3. Yes; the rule applies to the day of loading, not the day of unloading
  4. No; the rule excludes all cows in the final third of pregnancy
Answer and working

B. No; the final 10% starts at about day 255, so she is within it

The final 10% of 283 days is 28.3 days, so it starts at 283 - 28.3 = about day 255. On day 262 she is within it at planned unloading and is unfit. WOAH ties the rule to the time of planned unloading, not loading, and the 'final third' is not the standard.

6 · Welfare at slaughter · easy

Where should a penetrating captive bolt be placed on an adult cow?

  1. Behind the poll, aimed towards the angle of the jaw on the same side
  2. Where lines from each eye to the base of the opposite horn cross
  3. Midway between the eyes, at the level of the lower eyelids
  4. On the side of the head, just in front of the base of the ear
Answer and working

B. Where lines from each eye to the base of the opposite horn cross

The standard frontal site for cattle is the intersection of lines from each eye to the opposite horn base, aimed along the axis of the brain. Placing it at eye level misses the brain; the poll position is used for horned sheep.

7 · Welfare at slaughter · medium

Where should a captive bolt be placed for a horned adult sheep?

  1. On the frontal bone between the eyes, aimed towards the tail
  2. Behind the poll, aimed towards the chin
  3. Over the temporal fossa, aimed towards the opposite eye
  4. On the midline at eye level, aimed towards the throat
Answer and working

B. Behind the poll, aimed towards the chin

The horns block the top-of-head site, so horned sheep are shot behind the poll aimed towards the chin. Polled sheep are shot on the top of the head aimed towards the throat; the frontal-to-tail aim describes pigs.

8 · Handling and restraint · easy

According to WOAH guidance, electric goads may be used, if at all:

  1. Routinely on the head of any animal that stops moving in a race
  2. Only in extreme cases on the hindquarters of adult cattle and pigs
  3. On calves and lambs that will not move in the loading ramp
  4. On the anogenital region where the response is quickest
Answer and working

B. Only in extreme cases on the hindquarters of adult cattle and pigs

WOAH limits goads to extreme cases on the hindquarters of adult cattle and pigs that refuse to move, never on sensitive areas such as eyes, mouth, ears, anogenital region or belly. National rules are often stricter.

9 · Handling and restraint · hard

A dairy farm has a high rate of residual milk and kicking in the parlour. Stockpeople shout and slap cows to move them. Which intervention has the best evidence?

  1. Stockperson training to change attitudes and handling, reducing fear of people
  2. Giving routine oxytocin injections before every milking to force milk let-down
  3. Installing an electric prod at the parlour entrance to speed cow flow
  4. Replacing the stockpeople with automated gates and no human contact
Answer and working

A. Stockperson training to change attitudes and handling, reducing fear of people

Hemsworth and colleagues showed that aversive handling raises fear of humans, reducing milk let-down and productivity, and that training stockpeople improves both welfare and production. Routine oxytocin and prods treat symptoms and add stress.

10 · Environmental enrichment · medium

Under EU pig legislation, which provision best meets the requirement for manipulable material for growing pigs?

  1. A single metal chain hung in the middle of the pen at the pigs' shoulder height
  2. Straw, hay or similar fibrous material that pigs can root, chew and destroy
  3. A hard plastic ball on a solid floor that pigs can push around
  4. A radio playing music in the shed during working hours only
Answer and working

B. Straw, hay or similar fibrous material that pigs can root, chew and destroy

Directive 2008/120/EC requires permanent access to sufficient material for investigation and manipulation, and materials that can be rooted, chewed and destroyed, such as straw, are the most effective. Under Commission Recommendation (EU) 2016/336, hard objects such as chains alone are regarded as insufficient.
