Use of chicken or chukar egg yolk with two cryoprotectants for preservation of stallion semen
The use of chicken egg yolk for the protection of spermatozoa during cryopreservation iscommon practice in the equine industry. The substitution of quail egg yolk for chicken egg yolkfor the cryopreservation of poitou jackass sperm has been shown to increase both post-thawmotility and the percentage of intact acrosomes (PIA). Chukar egg yolkhas been shown to be similar in lipid content to quail egg yolk and yields more yolk per egg. In addition, the use of ethylene glycol as a cryoprotectant has been shown to yieldresults similar to those obtained with glycerol. Theobjective of the present study was to compare chukar egg yolk to chicken egg yolk with eitherglycerol or ethylene glycol as a cryoprotectant.
