Abstract:

Chinese local livestock breeds, through continuous evolution and adaptation, have become well-suited to their local agricultural ecological environments. Although they may exhibit lower performance in certain production traits, they possess numerous advantages such as high environmental adaptability, tolerance to coarse feeds, and strong disease resistance. These qualities make them indispensable for crossbreeding and the development of new breeds. In recent years, driven solely by the pursuit of economic efficiency and productivity, superior foreign breeds have been extensively introduced. This has led to the gradual phasing out of many domestic local breeds, replaced by their foreign counterparts, posing severe threats to the conservation of domestic local breed resources. With the advancement of cryobiology, the use of biobanks for cryopreservation has become a widely adopted method for conserving germplasm resources. However, during the cryopreservation of animal germplasm, oxidative stress significantly constrains their long-term preservation. Studies have shown that adding certain antioxidant compounds can effectively mitigate oxidative stress and prevent cryodamage to cells. However, traditional antioxidants suffer from low bioavailability and poor clinical efficacy. Nanoparticles (NPs), as an emerging material, possess unique physical structures that enhance bioavailability. This has led to their widespread application in fields such as assisted reproductive technologies, biomedicine, biopharmaceutics, and cosmetics. Therefore, this review focuses on the emerging applications and efficacy of nanoparticles in cryopreservation. It summarizes some of the most promising research progress and comprehensively discusses both the limitations and advantages of using nanoparticles for the cryopreservation of animal germplasm resources. The aim is to provide novel solutions for the cryopreservation of animal genetic resources.
