CANADA - A new product designed to mitigate pain in swine during painful procedures is expected to be submitted to Health Canada for approval by this fall, writes Bruce Cochrane.Effective July 1, under changes to Canada's Pig Code of Practice, pork producers are required to provide pain mitigation during painful procedures such as tail docking and castration.Dr Merle Olson, the research director with Alberta Veterinary Laboratories and Solvet, says, right now because there are no products approved for mitigating pain in piglets, veterinarians are forced to use products off label.
