Is gene editing an acceptable alternative to castration in pigs?

Area of Science:

• Agricultural Science
• Biotechnology
• Animal Welfare

Background:

• Surgical castration of male pigs is standard practice to prevent boar taint but causes pain.
• Gene modification offers a potential alternative to surgical castration for eliminating boar taint.

Purpose of the Study:

• To assess public acceptability of gene modification in male pigs as an alternative to surgical castration.
• To explore factors influencing public perception and identify key concerns regarding this biotechnology.

Main Methods:

• A mixed-methods approach was employed, combining quantitative surveys with qualitative analysis.
• 570 participants in southern Brazil provided data analyzed using multinomial logistic regression and Spearman correlations.
• Qualitative responses were coded into themes to understand the reasoning behind participants' stances.

Main Results:

• 56% of participants found gene modification of male pigs acceptable.
• Acceptability was positively associated with perceived benefits and negatively with perceived risks.
• Knowledge of genetic biotechnologies and awareness of castration issues were low and unrelated to acceptability.
• Concerns about unforeseen downstream consequences were raised by over 80% of participants.

Conclusions:

• Perceived improvements in animal welfare can foster public support for gene editing in food animals.
• Addressing and communicating potential risks are crucial for gaining wider public acceptance.
• Further public engagement is needed to clarify risks and benefits of gene modification in livestock.
