TapTechNews May 14th news, the innovative team of chicken genetic breeding at the Beijing Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences has successfully achieved live recovery of chicken frozen ovarian tissue using in situ transplantation technology, which refers to the surgery of transplanting the donor's organs to the original anatomical position of the recipient for the first time.
It is reported that the team successfully transplanted frozen ovarian tissue from the Hefei chicken into the Leghorn chicken, and successfully hatched a Leghorn chick with the Hefei chicken genetic background.
This is the first case in China that a chick was produced through the live recovery of glassified frozen ovarian tissue using in situ transplantation technology, breaking through the difficulty of preserving the complete genetic genome of frozen sperm of a single sex. The team will evaluate the recovered individuals and further study ways to improve recovery efficiency.
Officials also revealed that the team had previously pioneered chicken sperm cryopreservation technology in China, which has been successfully applied to collect and preserve more than 30 rare and endangered chicken genetic resources in the national domestic animal germplasm repository, taking a crucial step forward in the protection and innovation of our country's poultry resources.
The success of this experiment marks that China can achieve live recovery of chicken genetic resources across time and space through the frozen preservation of semen and ovarian tissue, which is a milestone for the long-term effective preservation of chicken genetic resources and the rescue protection of endangered resources in our country.
