Semen cryopreservation may be one of the main biotechnologies of animal reproduction since it provides wide genetic diffusion of superior boars, creation of germplasm bank, as well as improving semen biosecurity, promoting a great impact on global production . However, regarding swine, this biotechnology is still little used, accounting for no more than 1% of the artificial inseminations. This is mainly due to injuries caused during cryopreservation process, and related to the great variability in the semen freezeability between the individuals, making it impossible in commercial use. In this way, the present study aims to highlight the various aspects that are being explored, in order to achieve improvements in the quality of frozen boar semen and consequently make it possible to use it commercially.(AU)
