Effects Of Flow Rate, Gas Type And Disease Status On The Welfare Of Sucking And Weaned Pigs During Gas Euthanasia, Larry Joseph Sadler
Graduate Theses and Dissertations
Gas euthanasia of swine on farms is increasingly common. However, there is controversy regarding pig welfare during gas euthanasia and research must be conducted to establish best practices ensuring minimal pain and distress. The objectives of these studies were to determine pig welfare and efficacy of processes with various gas euthanasia procedures: gas type (carbon dioxide, argon, carbon dioxide:argon mixture), flow rate (20%, 35%, 50%, prefill), age (neonate, weaned) and disease status of the pig (respiratory disease/depression vs. other reasons). Euthanasia with inhalant gases can produce confounding effects on physiologic responses, therefore behavior was chosen as the primary ...
