ANALYSIS - Modern pig production has an inherent need for the euthanasia of piglets for various reasons, and research from the University of Bristol shows a humane option to euthanize that includes no pain to the animal.Through interactions with larger operations, Randall Bock, President and CEO of Bock Industries, said the demands of retailers are pushing greater emphasis on animal welfare, so they created humane tools that are university tested for euthanizing stock on-farm. "We're very proud of our affiliation with the University of Bristol in the UK and consider them the number one animal welfare research group in the world," he said. "They have done some lab studies and field trials confirming humane the Zephyr-EXL product for euthanasia of piglets up to twenty pounds."
