Nanotechnology is transforming animal husbandry by offering precision tools for genetic improvement, reproductive management, and disease control. This chapter explores the integration of nanomaterials and nanoscale delivery systems in livestock breeding and reproduction. Nanoparticles (NPs) enable targeted gene delivery, including CRISPR/Cas9 systems, with improved efficiency and reduced cytotoxicity compared to traditional vectors. In reproductive biotechnology, NPs enhance sperm selection, oocyte maturation, cryopreservation, and controlled hormone release, increasing fertility outcomes while reducing intervention frequency. Quantum dots facilitate real-time bioimaging of gametes, and magnetic nanopurification improves semen quality. Moreover, nanotechnology plays a pivotal role in epigenetic regulation, biosensing, and disease resistance, offering potential for antibiotic alternatives and sustainable breeding practices. Despite these advances, challenges such as nanoparticle toxicity, regulatory uncertainties, and delivery inefficiencies persist. The chapter emphasizes the need for interdisciplinary collaboration, safety assessment, and responsible deployment to fully harness nanotechnology’s potential in animal agriculture. With continued innovation, nanotechnology promises to enhance productivity, welfare, and sustainability in livestock systems, shaping the future of precision animal biotechnology.

摘要

Nanotechnology is transforming animal husbandry by offering precision tools for genetic improvement, reproductive management, and disease control. This chapter explores the integration of nanomaterials and nanoscale delivery systems in livestock breeding and reproduction. Nanoparticles (NPs) enable targeted gene delivery, including CRISPR/Cas9 systems, with improved efficiency and reduced cytotoxicity compared to traditional vectors. In reproductive biotechnology, NPs enhance sperm selection, oocyte maturation, cryopreservation, and controlled hormone release, increasing fertility outcomes while reducing intervention frequency. Quantum dots facilitate real-time bioimaging of gametes, and magnetic nanopurification improves semen quality. Moreover, nanotechnology plays a pivotal role in epigenetic regulation, biosensing, and disease resistance, offering potential for antibiotic alternatives and sustainable breeding practices. Despite these advances, challenges such as nanoparticle toxicity, regulatory uncertainties, and delivery inefficiencies persist. The chapter emphasizes the need for interdisciplinary collaboration, safety assessment, and responsible deployment to fully harness nanotechnology’s potential in animal agriculture. With continued innovation, nanotechnology promises to enhance productivity, welfare, and sustainability in livestock systems, shaping the future of precision animal biotechnology.
