The influence of in-vitro culture and cooling on the survival and development of cow embryos.
Cow morulae cultured in a phosphate-buffered medium containing serum developed normally and retained viability when transferred to recipients. Unlike earlier cleavage stages, cow blastocysts tolerated cooling to 0 degrees C and retained viability after storage for 48 hr at 0 degrees C when transferred to recipients.
