Our purpose is to make the work of moving pigs safer and easier by helping handlers understand the patterns pigs follow when responding to handlers, and that handlers’ actions determine how pigs respond to them.
 
BACKGROUND:
 
I have been asked to outline my concerns about the pig handling content of Canada’s new “Code of Practice for the Care and Handling of Pigs”. Previous blogs in this series have dealt with:
 
General concerns about the flight zone / point of balance model used by Canada’s codes and other training documents, primarily:
 
Pig’s flight zone v.s. handler`s bubble
History of the flight zone diagram and its applicability on-farm
Details of the flight zone / point of balance model as used by Canada’s code:
 
The importance of releasing pressure
Problems with the point of balance
 
Today’s article will deal with the blind spot and other senses.
 
Canada’s “Code of Practice for the Care and Handling of Pigs” is at:
