Conventional freezing and vitrification of germplasm and embryos have given veterinarians, scientists and producers alternatives in herd reproduction. While routinely used for cattle, there are few preservation methods available or effective for swine embryos. This paper discusses germplasm preservation without elaborating on technical aspects, as well as global potential for germplasm and embryo preservation and how it would provide a foundation for effective utilization of the world's best genetic resources on a global basis while modernizing production and enhancing genetic improvement programs. It discusses novel development of embryo cryopreservation by vitrification in the pig, illustrating how modern science can be applied to solve difficult biological questions. Finally, it discusses conceptually how germplasm preservation may be applied and implemented in propagating desirable genetics on a global basis. It is evident from the cattle industry what an impact germplasm or embryo preservation can have on the global production. |
