Techniques such as RAD-seq and RNA-seq have been instrumental in identifying genetic markers and selection signatures associated with disease resistance. For instance, RAD-seq technology has been used to identify genes related to immunity and disease resistance in Yunling goats, providing a scientific basis for breeding programs aimed at enhancing disease resistance (Chen et al., 2022). Similarly, RNA-seq has facilitated the discovery of genomic variants in Creole goats that are resistant to gastrointestinal nematode infections, highlighting the potential of these technologies in molecular breeding (Aboshady et al., 2021). These innovations allow for a more precise selection of traits, thereby improving the overall health and productivity of goat populations. 7.2 Integrated approaches for enhancing disease resistance An integrated approach combining quantitative and functional genomics with large-scale data collection and epidemiological prediction is crucial for advancing disease resistance in goats. This approach enables breeders to select for enhanced resistance to a variety of diseases by understanding the genetic control of resistance and genetic variations (Mandal et al., 2018). Studies have shown that genetic selection for resistance to diseases such as caprine arthritis encephalitis and gastrointestinal nematode infections can be effective when combined with proper management strategies (Estrada-Reyes et al., 2019; Schultz et al., 2020). By integrating these methods, breeders can develop more resilient goat populations that are better equipped to withstand disease pressures. 7.3 The role of biotechnology in shaping future breeding programs Biotechnology plays a pivotal role in shaping future breeding programs for disease resistance in goats. The use of molecular genetic tools, such as PCR-DNA sequencing, has identified SNPs associated with disease resistance, providing a practical management technique for selective breeding (Ateya et al., 2023). Additionally, the identification of specific alleles, such as those conferring resistance to transmissible spongiform encephalopathies, underscores the potential of genetic resistance as a tool for controlling diseases in goat populations (Ricci et al., 2017). By leveraging biotechnological advancements, breeding programs can be tailored to enhance disease resistance, ultimately leading to more sustainable and profitable goat production systems (Amayi et al., 2021). In summary, the future of goat disease resistance research lies in the integration of genomic technologies, comprehensive breeding strategies, and biotechnological innovations. These approaches promise to enhance the genetic resilience of goat populations, ensuring their health and productivity in the face of evolving disease challenges. 8 Concluding Remarks Research into genetic selection for disease resistance in goats has revealed significant insights. Studies have identified numerous genes and pathways associated with immunity and disease resistance, such as those found in Yunling goats, which exhibit strong disease resistance and adaptability. Similarly, genetic markers linked to pneumonia resistance have been identified in Baladi goats, highlighting the potential for using genetic tools to enhance disease resistance. The identification of genomic variants in Creole goats resistant to gastrointestinal nematodes further underscores the role of genetic selection in improving disease resistance. Additionally, the positive selection of genes like IL-33 in Chinese goats suggests a genetic basis for enhanced immune responses. The future of goat disease resistance through genetic selection looks promising, with ongoing research likely to uncover more genetic markers and pathways that can be targeted for breeding programs. The integration of genomic technologies, such as RAD-seq and RNA-seq, will continue to enhance our understanding of the genetic basis of disease resistance. Moreover, the development of breeding programs that incorporate genetic resistance to diseases like scrapie and gastrointestinal nematodes will be crucial in improving herd health and productivity. As genetic selection becomes more refined, it will play a pivotal role in sustainable goat farming practices.
