In order to conserve genetic resources efficiently,
the simple freezing temperature control method for
pig semen by a small capacity straw using a
Styrofoam container and the gricerin equilibrium
time were studied. In the present study, using the
simple equipment of a Styrofoam container it was
confirmed that the cryopreservation of pig semen in
a 0.5ml straw was possible by adjusting the distance
of the straw from the liquid nitrogen surface. In
addition, since the simple freezing method with a
small capacity straw of 0.5ml is utilizable for in vitro
fertilization or tubal fertilization, it seems to be
useful for the conservation etc. of genetic resources.
