SVF Foundation preserves germplasm (semen and embryos) from rare and endangered breeds of food and fiber livestock. In collaboration with Tufts University’s Cummings School of Veterinary Medicine, SVF elevates rare-breed conservation to a new level, through the cryopreservation of germplasm. Collecting 200 embryos and 3,000 straws of semen per breed, SVF will be able to reawaken a breed, with its full genetic diversity, within one generation. This library of frozen material is vital to the protection of the world’s food supply.
