Genetic Engineering and Animal Welfare Implications

Genetic engineering offers potential welfare benefits through disease-resistant animals and reduced suffering, but also creates new welfare risks requiring careful ethical assessment.

Key Facts

Gene editing has been used to produce pigs resistant to Porcine Reproductive and Respiratory Syndrome virus
Hornless cattle produced through gene editing would eliminate the need for painful dehorning
GE salmon engineered for rapid growth have been approved in the US and Canada for commercial production
Off-target gene editing effects creating unanticipated welfare problems remain a significant concern

Welfare Considerations

Genetic engineering of animals presents a complex welfare landscape. Applications that eliminate the need for painful procedures like dehorning represent genuine welfare advances. Those that accelerate growth may recreate the welfare problems seen in conventionally bred broilers and GE salmon. Each application requires independent welfare assessment rather than blanket acceptance or rejection.

What You Can Do

Support welfare assessment requirements as a prerequisite for approval of genetically engineered animals
Engage with the specific welfare implications of each GE application rather than treating them as uniform
Advocate for labeling of GE animal products to enable informed consumer choice
Support research into welfare outcomes of existing GE animal populations
Donate to organizations developing ethical frameworks for animal genetic engineering assessment
