Abstract

The present invention discloses applications of the compatibility of lycopene and sesamol in livestock semen freezing storage agents, and provides a livestock semen freezing storage agent, which can significantly improve the survival rate of livestock sperms, and comprises a freezing base liquid, egg yolk, lycopene and sesamol. The present invention further provides another livestock semen freezing storage agent, which comprises a freezing base liquid, egg yolk, lycopene, sesamol and glycerol. According to the present invention, the compatibility of lycopene and sesamol is firstly used as the anti-freezing agent for the freezing storage of the semen of pigs, sheep and cows, and the obtained livestock semen freezing storage agent can be used for the artificial insemination of the test tube freezing semen of pigs, sheep and cows, and the long-term storage and the after-long-distance-transportation semen deposition of the semen after the super-temperature freezing, and can significantly improve the survival rate, the acrosome integrity and the plasma membrane integrity of the frozen-thawed perms of pigs, sheep and cows,.

Description

technical field

[0001] The invention belongs to the technical field of ultra-low temperature cryopreservation of mammalian semen, and in particular relates to the application of the combination of lycopene and sesamol as an antifreeze agent in the cryopreservation of livestock semen Background technique

[0002] The development of semen cryopreservation technology solves the problem that semen cannot be preserved for a long time, and separates semen collection and fertilization in time and space, which greatly prolongs the storage time of sperm in vitro, improves the utilization rate of excellent breeding stock, and facilitates precious inheritance material preservation.

[0003] Sperm are sensitive to temperature changes. In the process of freezing and cooling, sperm are susceptible to freezing damage, mainly including physical damage, chemical damage and oxidative damage. However, compared with fresh semen, the motility rate, acrosome integrity rate, mitochondrial activit...
