Current regulations primarily focus on genetic modifications and may not adequately address the unique aspects of epigenetic interventions (Henikoff and Greally, 2016). There is a need for new guidelines that consider the reversible and potentially transient nature of epigenetic changes, as well as their long-term impacts on animal health and welfare (Delcuve et al., 2009). Additionally, the lack of standardized methods for detecting and measuring epigenetic modifications poses challenges for regulatory oversight and enforcement. Developing robust regulatory policies will require collaboration between scientists, policymakers, and industry stakeholders to ensure that epigenetic breeding practices are safe, ethical, and transparent. 6 Future Perspectives 6.1 Emerging research areas in epigenetics Emerging research areas in epigenetics are rapidly expanding, offering new insights and opportunities for pet breeding. One significant area of focus is the understanding of how environmental factors influence epigenetic modifications and, consequently, animal phenotypes. Recent studies have shown that virtually all environmental factors can affect an animal's phenotype through epigenetic mechanisms, which include alterations in chromatin structure and gene expression patterns (Kim and Kim, 2021). Additionally, the identification and characterization of different types of epialleles-permanent, temporary, and intergenerational-are providing new models to explain the complex interactions between genetics, epigenetics, and the environment (Roudbar et al., 2015). These advancements are paving the way for more precise and effective breeding strategies that go beyond traditional genetic approaches. 6.2 Potential applications in personalized breeding The potential applications of epigenetics in personalized breeding are vast and promising. By incorporating epigenetic information, breeders can achieve a more comprehensive understanding of an animal's phenotype, which is influenced by both genetic and environmental factors. This holistic approach can lead to more accurate estimations of breeding values and reduce biases in selection processes. Furthermore, the integration of epigenetic data can help identify specific epigenetic markers associated with desirable traits, enabling breeders to select animals with optimal genetic and epigenetic profiles (Yakovlev, 2018). This personalized breeding strategy can enhance the overall health, performance, and adaptability of pets, ultimately leading to improved breeding outcomes. 6.3 Recommendations for breeders For breeders looking to incorporate epigenetic insights into their practices, several recommendations can be made. First, breeders should stay informed about the latest research in epigenetics and its implications for animal breeding (Crisp et al., 2021). Understanding the mechanisms of epigenetic regulation and the impact of environmental factors on gene expression is crucial for making informed breeding decisions. Second, breeders should consider using epigenetic markers in conjunction with traditional genetic markers to select animals with desirable traits. This combined approach can provide a more accurate assessment of an animal's potential and improve breeding outcomes. Finally, breeders should collaborate with researchers and utilize advanced technologies, such as epigenomic profiling, to gain deeper insights into the epigenetic landscape of their breeding populations. By embracing these recommendations, breeders can harness the power of epigenetics to enhance the quality and success of their breeding programs.
