GENETICS, REPRODUCTION AND REFRIGERATION.

Author(s) : RENARD J. P.

Summary

THE DISCOVERY NEARLY 40 YEARS AGO THAT SPERMATOZOONS SURVIVE AFTER FREEZING IN THE PRESENCE OF GLYCEROL, HAS ENABLED THE CREATION OF A REPRODUCTION INDUSTRY FOR CATTLE. EMBRYONIC TRANSPLANTATION, IS NOW EMPLOYED FOR MULTIPLYING THE DESCENDANTS OF THE BEST FEMALES OF A HERD OR FLOCK. THE FREEZING OF EMBRYOS OFFERS NUMEROUS POSSIBILITIES, SUCH AS REPRODUCING ANIMALS OF HIGH GENETIC VALUE FROM AN ANIMAL POPULATION WHICH IS POORLY PRODUCTIVE BUT WELL ADAPTED TO ITS ENVIRONMENT ; IT CONTRIBUTES TO SAFEGUARDING THE GENETIC HERITAGE OF RACES OR BREEDS FACING EXTINCTION. ONE WILL SOON BE ABLE TO PREDICT THE SEX OF EMBRYOS OR MULTIPLY THEM BY NUCLEAR TRANSFER. THANKS TO REFRIGERATION, ONE WILL THEREFORE SEE THE APPEARANCE OF NEW MEANS OF REPRODUCING ANIMAL SPECIES WHICH WILL ENABLE ONE TO DIVERSIFY HUSOHRRS THE GAMETES CONSTITUTE EXCELLENT MODELS.
