Description
Technical field
The invention belongs to cattle technology of artificial insemination field, more particularly, to a kind of gl and tcm199 as bull semen diluent and
The compound method of freezing liquid and using method.
Background technology
The modes of reproduction of cattle includes this friendship and artificial insemination, artificial insemination divide again fresh join and jelly is joined, entered using straw frozen semen
Row is long-range and concentrates enforcement artificial insemination to be topmost cows modes of reproduction.Therefore, the quality of straw frozen semen is to ensure that manually
The key link of insemination conception rate.The quality of straw frozen semen is subject to for smart bull health status, raise competence, semen quality, tubule
Freeze the impact of smart making link and preservation condition, can be carried out manually controlling in these links in addition to straw frozen semen making, and
Straw frozen semen making link is affected larger by freezing liquid, freezing method.The cryoprotective agent of conventional freezing liquid is glycerol and ovum
Huang, has that viscosity is excessive, yolk lipochondrion is big and uneven in the application, impact sperm motility speed and conception rate.
In other cells and Embryo Cryopreservation Technology research process, find that buffer agent trishydroxymethylaminomethane (tris) delays
Substantially, Sodium Pyruvate can meet the portion of energy of cell and embryo cutting, it is developed and has played notable work for punching effect
With.We utilize the biochemical characteristic of both materials, are introduced in the dilution and cryoprotection system of cattle seminal fluid, and by tight
Lattice test measure it was demonstrated that they dilution and protection to cattle seminal fluid have obvious effect really.
The shortcoming of prior art:
1st, diluent granule is big, viscosity is high.Based on yolk, yolk is not handled by and direct the diluent of prior art
Use, because yolk protein is big, cause the bulk granule in dilution seminal fluid and frozen semen to increase, sperm is often around bulk granule
Assemble and move, reduce the movement velocity of sperm, decrease Free Sperms, decrease the quantity to ovum motile.
2nd, operating technology is complicated.The operating technology of prior art is excessively complicated, is adapted only to factorial praluction, is not suitable for little model
Enclose use.
