“…Besides glycerol, dimethylsulfoxide (DMSO) (Van Voorst and Leenstra, 1995) and dimethylacetamide (DMA) (Tselutin et al, 1999) have been used to cryopreserve chicken sperm with varying degrees of success. Of these 3 cryoprotective agents, glycerol has been the most widely used for freezing chicken semen because it is associated with the highest postthaw fertility rate (Tajima et al, 1990).…”

Conservation of avian genetic resources is important, as 13.0% (1,313/10,064) of known avian species are currently categorized as endangered by the International Union for Conservation of Nature and Natural Resources (IUCN, 2012). Development of an integrated system for conservation of avian genetics is necessary; however, germplasm conservation systems developed for mammals cannot be applied directly to avians, primarily due to the unique anatomical and physiological characteristics of the avian egg. Thus an alternative strategy for conservation of oviparous species of animals must be developed. Recent technological developments for producing germline chimeras by the transfer of primordial germ cells into recipient embryos has enabled the conservation and retrieval of chicken genetic resources in their complete form. Furthermore, the possibility of propagating endangered wild birds through interspecies germline chimeras has been proposed.In the present review, the current status of avian genetic resource conservation is presented with a focus on the following 4 topics: 1) semen cryopreservation, 2) germline chimeras, 3) somatic nuclear transfer, and 4) other related technologies.

“…Glycerol is probably the most efficient and least toxic cryoprotectant for chicken sperm (Chalah et al, 1999;Tselutin et al, 1999) but its introduction into the vagina with sperm results in the total absence of fertilisation if present at final concentrations >2% in the semen dose (Lake, 1986). In order to counteract this 'contraceptive' effect, it is therefore necessary to undertake its slow removal prior to insemination.…”

Specific features of in vivo and in vitro sperm storage in birds

This review focuses on some of the main features of sperm selection and storage in birds mainly on the basis of studies performed in poultry species, with emphasis on the initial selection of sperm at the female vagina level prior to migration towards the sperm storage tubules. Sperm originating from low-quality males or subjected to inappropriate in vitro storage conditions are rapidly discarded, resulting in impaired fertility in corresponding flocks. In the absence of accessible and appropriate technology for matching the 'storing' potential of sperm in the oviduct, conditions for prolonged sperm storage under a liquid (through the use of semen extenders) or a solid state (cryopreservation) have received only limited attention, despite their potential interest to facilitate male and female management in poultry flocks. Despite this, technology for shortterm liquid storage is currently used in turkeys, guinea fowl and muscovy ducks and also in progress in chickens. In addition, technology for cryopreservation of avian semen has become available for some species (chicken, goose) to facilitate the management of genetic resources, including the preservation of rare and economically important breeds.
