Caretaker attitudes toward swine euthanasia.

Timely euthanasia is a fundamental part of safeguarding swine welfare by reducing suffering when compromised pigs are unable to recover. The quality and appropriateness of timely euthanasia rely mainly on the knowledge and experience of the individual caretaker but may also be affected by caretaker attitudes toward euthanasia. However, literature on caretaker attitudes toward swine euthanasia is lacking. This study investigated caretaker attitudes, perceived knowledge, and confidence in performing on-farm timely euthanasia. A total of 84 caretakers from eight swine farms (ranging in size from 1,300 to 7,000 sows) participated in a survey designed to investigate attitudes toward swine and swine euthanasia. Caretaker's ages ranged from 18 to 59 yr with an average work experience of 8.5 yr. The majority of participants worked in either farrowing or breeding units. Survey questions were designed to assess caretakers' attitudes and attributes (empathy affect, empathy attribution, attitudes toward pigs, feeling bad about euthanizing pigs, and assumptions about pigs' emotional capabilities), decision-making skills (confidence in identifying compromised pigs or relying on coworkers to make decisions), and euthanasia skillset (confidence in performing euthanasia, training, and perceived level of knowledge). Using cluster analysis to analyze survey answers, three distinct groups of caretakers were identified: 1) confident and empathetic; 2) Confident, knowledgeable, and detached; and 3) unconfident and lacking knowledge. The survey results showed that empathy attribution was strongly correlated with empathy affect ( = 0.571, < 0.01) and that empathy affect and empathy attribution were higher in female caretakers compared with male caretakers ( < 0.05). A risk analysis that included previously identified clusters showed that females were more likely to be grouped among caretakers that were confident and empathetic ( = 0.04), and caretakers with more than 2 yr of swine experience were more likely to be grouped as confident and skilled ( = 0.01), while the unconfident and empathetic were more likely to have had less than 2 yr of experience ( = 0.04). This study provides important information about variability in caretaker experience as well as their attitudes toward pigs and timely euthanasia. Increased knowledge about swine caretaker attitudes may be used to implement training and euthanasia protocols to increase both human and pig welfare on farm.
