Zusammenfassung:	The process according to the invention consists in that the freshly collected ram semen is first diluted at between 25 DEG and 32 DEG C and notably at 30 DEG C, in a diluent without glycerol containing lactose and egg yolk, and in then diluting, at between 3 DEG and 5 DEG C and notably at 4 DEG C, the mixture previously obtained in a diluent containing glycerol, said diluent essentially comprising powdered milk and sodium citrate, in conditioning in straws the so diluted semen and in freezing it in liquid nitrogen at about -75 DEG C. The invention also relates to the diluent used in the above process.
