Patent 3311

This is the first trial that conducted in the world for cryopreservation of avian semen. Avian spermatozoa are characterized by having very high amount of polyunsaturated fatty acids which render these gametes are susceptible to cold shock during freezing process. So in this invention we innovated a complete system for freezing and thawing avian semen. Results revealed that the use the new system for cryopreservation of avian semen had significant results as regards spermatozoa livability, motility and normality and fertility and hatchability rates.
