Artificial insemination has been a critical component of reproduction in turkeys since the 1960's and is used almost exclusively for commercial flock production. Significant progress was made in developing semen diluents and preservation procedures for poultry semen, liquid storage of semen at refrigerated temperatures for up to 6 hours in turkeys and 24 hours in chickens can result in fertility levels comparable to freshly inseminated semen. Although it was the serendipitous discovery of glycerol's cryoprotective qualities in freezing chicken semen that advanced semen cryopreservation technology for all species, freezing procedures for poultry sperm are not cost effective for commercial flock production.
