摘要

process of freeze / epididymal semen cryopreservation and / or post-mortem freezing. it is to this patent, a process of freezing / cryopreservation of epididymal semen and / or post-mortem freezing, from the head and tail of the epididymis of cattle, buffaloes, dogs, goats, horses, sheep and pigs belonging the technical areas of biotechnology applied to animal reproduction and cryobiology. its importance refers to the possibility of freezing the semen samples after the death of high breeding value zootechnical thereby to retain the genetic material which forms part of a major germplasm collections world that is Brazil. the present invention provides a process of freeze / cryopreservation of epididymal sperm and / or frozen post-mortem, allowing the frozen semen samples after the death of reproductive high zootechnical value in order to preserve the genetic material from the head and tail epididymis of cattle, buffaloes, dogs, goats, horses, sheep and pigs, through eight main stages: 1. preparation of the testes; 2. A washing and drying of the testis; 3.- Extraction of the spermatozoa; 4. laboratory analysis; 5.- dilution; 6.- cryopreservation; 7. 8.- freezing and storage.
