  • Implementing surveillance systems and phenotype assessments for newly created lines.
  • Employing welfare strategies such as condition treatment and gene expression control.

    • Main Results:

    • Genetically engineered animals offer more accurate disease models and precise pathogenesis studies.
    • Increased use of mice as models is replacing more sentient species and improving research quality.
    • The study of genetically engineered animals may lead to a decrease in the overall number of animals used in research.
    • Challenges exist in protocol review and care for genetically altered animals.

    Conclusions:

    • Genetically engineered animals are vital for advancing physiological and disease research, offering hope for improved patient therapies.
    • Shared responsibility among institutional animal care and use committees, veterinary staff, and researchers is essential for addressing welfare concerns.
    • Proactive monitoring, phenotype assessment, and welfare interventions are critical for the ethical use of genetically engineered animals in research.
