The 3 P’s of avian influenza Prevent, Plan, Practice

Avian Influenza has become endemic in many parts of the word. In it’s current form it has been around since 1997 and although thy virus types have changed, emergency response, management & control are still a hot issue. In this article published in 2006 in the US magazine Poultry Perspectives, the subject what to do during crisis situations is presented. The conclusions are still valid today and may help to prevent large-scale outbreaks.

How do humans react on Anoxia?

The Anoxia method is the first slaughter technique based on the principle of total lack of oxygen. One of the main reasons is the lack of unnecessary stress or pain caused by Anoxia, as described in the scientific report published in Poultry Science of May, 2013.

Only Professionals recognize that Anoxia as life-threatening phenomenon:in aviation; mountain climbing; and deep-sea diving. The question is: what happens with your brain when it is confronted with total absence of oxygen and how dangerous it when you breathe in pure nitrogen? Time to find out. A team of two young Dutch scientists put themselves on the test and went to the Military aviation test facility in Soesterberg to find it out. At this facility, pilots are trained to recognize the signs and learn how to deal with it.

In the category “Don’t try this at home”, one of the guys takes of his oxygen mask, after the oxygen in the conditioned room they are staying in has been completely pumped out. What happened to him, confronted to 100% nitrogen? See for yourself…

Introduction on pig management and procedures related to killing on the farm

Welcome to the introduction to module 1. In this module, we will handle the theories behind animal welfare, the legislation, farm management, pigs behavior and handling and the role of the Veterinary Inspection.

The protection of animals at the time of slaughter or killing is a matter of public concern that affects consumer attitudes towards agricultural products. The protection of animals at the time of slaughter or killing is the duty of the farmer or any person involved in the killing of animals. They need to take the necessary measures to avoid pain and minimize the distress and suffering of animals.   Besides that, it is an ethical duty to kill productive animals which are in severe pain where there is no economically viable way to alleviate such pain, suffering and distress.  Good animal welfare management is influenced by the farm facility, people’s behavior and good understanding of the animals’ natural behavior as well as his behavior under stress.

 The requirement for the competence of staff handling animals at the farm should be specific enough to include in particular the following objectives in the context of the interaction and the species concerned:

  • Understand the ethical principles concerning the human-animal relationship
  • Show general knowledge and understanding of animal behavior
  • Identify and understand the signs of pain, suffering and distress including fear of animals
  • Show practical abilities in the foreseen interaction while preventing or limiting animals’ pain, suffering and distress
  • Show knowledge of the legal obligations related to the protection and welfare of animals
  • Prove the acquired and maintained competence through an independent and objective examination.

The pigs perspective

Staff – handlers approach should be balanced when handling animals to keep low level of stress. The same is true when the conditions on the farm suddenly change caused by an outbreak of a disease.

Animal welfare principles in a global context

Individuals, societies, cultures and religions vary considerably in what is considered “right action” when it comes to how animals should be treated. As a result there have been numerous attempts to define the term “animal welfare”, but as yet no universally agreed definition. In common usage welfare is perceived as a satisfactory or positive state and words such as “good health”; “well being” and “happiness” are frequently used.

 Some of the more recognized scientific definitions include: “Welfare, on a general level, is a state of complete mental and physical health where the animal is in harmony with its environment.” (Hughes 1976). More detailed approaches to try and define animal welfare revolve around three areas or questions:

  1. Physical state – Is the animal fit and healthy?
  2. Mental state – Is the animal happy? 
  3. Naturalness – Is the animal living a natural life?

Most agree that these three elements are not mutually exclusive and the aim should be to develop and manage systems which take into account all of these aspects.

Regulation EU1099/2009

This new EU legislation describes the rules for killing of animals bred or kept for the production of food etc. during slaughter, as well as the killing of animals for the purpose of depopulation and for related operations.

The OIE code

In 2007, the World Organization for Animal Health (OIE) adopted the Terrestrial Animal Health Code, which includes guidelines for the killing and slaughter of animals. In this module, we will follow mainly the definitions as described in the Terrestrial Animal Health Code of the International Standards of OiE, and the definition of animal welfare at time of killing as described in reg. EU1099/2009.

Temple Grandin

According to dr. Temple Grandin, one of the world most influential animal welfare specialists, animals are not things and the protection of animals at the time of slaughter or killing is a matter of public concern.  This module focuses on moments in life of animals to be considered to have high risks for animals experiencing stress and pain.
