Avian semen cryopreservation: what are the biological challenges?
The value of the ability to cryopreserve and store germplasm has long been recognized for indefinite preservation of genetic material, especially for at-risk populations. In contrast to domestic livestock species, cryogenic storage of poultry semen is not reliable enough for germplasm preservation. The relatively low fertilizing ability of frozen/thawed poultry sperm most likely results from ph...
متن کاملAdvances in avian semen cryopreservation
Semen cryopreservation in domestic birds has been studied extensively in the past fifty years. However, efficient methods to freeze semen of chicken of different breeds have emerged only in the last decade of the 20 century. Methods using cryoprotectants Glycerol, Dimethyl Acetamide and Dimethyl sulfoxide, slow or rapid freezing-thawing procedures, pellets or ampoules or straws packaging have b...
متن کاملCryopreservation of canine semen - new challenges.
Egg yolk (EY) protects cell membranes against cold shock, and it prevents or restores the loss of phospholipids from the membrane. EY has been widely used in semen extenders. It has been added to Tris-Glucose buffer and has been widely used for cooling and cryopreservation of canine semen. EY is not a defined entity, but a complex biological compound containing proteins, vitamins, phospholipids...

متن کاملAdvances in Boar Semen Cryopreservation
The present paper highlights aspects of the cryopreservation of boar semen, a species with particular large, fractionated ejaculates, and a cumbersome cryotechnology that had prevented its commercial application. With the dramatic increase of use of liquid pig semen for artificial breeding over the past decade, developments on cryopreservation alongside the routine use of stud boar semen for AI...
