  1. 1. Connecting the Dots: Health, Well-Being & Productivity John Deen College of Veterinary Medicine
  2. 2. • Humane Methods of Slaughter Act 1978 • extended the 1958 policy to all Federally inspected slaughter plants • Food Safety and Inspection Service (FSIS) enforces the Act • veterinarian and inspectors present
  3. 3. Committees… • • • • • • • • • AASV NPB PAACO CFI ACAW AVMA AAA FAO Validus
  4. 4. Certified Big Red Apple “For Large Animal Enrichment Scented for swine and stall animals’ pleasure”
  5. 5. Three points • Welfare is about pigs and not PR • Ethics are personal not institutional • Caregivers are the experts
  6. 6. Welfare is a classic economic problem: • Addressing unlimited demand with a very restricted amount of resources • Is it a profit maximization model with specific welfare constraints? • Is it an optimization model with values placed on welfare? • Is it a marketing problem?
  7. 7. Welfare policy • The efficient allocation of scarce resources to a population – Implicitly, some or all desired outcomes will not be maximized – Usually modeled across one species – Multiple species and needs create a difficult problem to solve
  8. 8. Who administers welfare policy? • • • • Government NGO’s Marketing chains Farmers • Do we improve welfare by moving the average or addressing outliers?
  9. 9. Five freedoms (FAWC- UK- 1993) Freedom from hunger and thirst Freedom from discomfort by providing ready access to fresh water and a diet to maintain full health and vigor by providing an appropriate environment including shelter and a comfortable resting area Freedom from pain, by prevention or rapid diagnosis and injury or disease treatment Freedom to express by providing sufficient space, proper normal behavior facilities and company of the animal's own kind Freedom from fear and by ensuring conditions and treatments, distress which avoid mental suffering
  10. 10. Negative states Thirst Hunger Malnutrition (predisposition) Hunger, Malaise Discomfort Pain Injury (predisposition) Pain Disease (predisposition) Malaise To express Normal Behavior Boredom (?) Fear Distress Are they signals?
  11. 11. Are Flourishing Animals Fine? 1. Yes – if they are functioning well (the performance axiom (Stan Curtis)) 2. Yes – feelings are designed to ensure proper function (evolutionary biology) 3. Maybe… but is it natural (right) (teleology and ontology)
  12. 12. Four Functions to Flourish • Feed – take in adequate nutrition • Fight – compete and adapt in difficult conditions (disease, heat etc) • Flight – avoid difficult adverse conditions • Reproduction – replacement
  13. 13. Failure to Flourish • • • • Feed intake/absorption inadequate Inability to adapt to adverse conditions Inability to avoid adverse conditions Inability to reproduce • • Inhibitions: • Physical • Environmental • Infectious • Other pigs •
  14. 14. What are the mechanisms of functional inhibition? • Physical – Inability or reluctance to move or position body to eat, reproduce etc • Inflammatory – Inhibition of appetite, reproduction, and competition • Pain – Behavioral inhibition of competing function

  22. 22. Aristotle: A Good Narrative • Logos is appeal based on logic or reason. • Ethos is appeal based on the character of the speaker. • Pathos is appeal based on emotion. – HL Green: The three types of persuasion, if you are a classically trained orator, are ethos, pathos, and logos. If your training was obtained in modern times, you have an additional toolstatistics.
