Cryoprotectants & Cryopreservation of Equine Semen: A Review of Industry Cryoprotectants and the Effects of Cryopreservation on Equine Semen Membranes
However, early efforts to incorporate AI into production schemes were limited by the functional lifespan of ejaculated spermatozoa. Therefore, widespread the use of AI Cryopreservation (CP) is the ability to store cells and maintain their integrity and viability at a sub-zero temperature until needed. Like some of the greatest discoveries, CP of semen was the result of a fortunate lab error. In...
متن کاملComparison of different diluents based on liposomes and egg yolk for ram semen cooling and cryopreservation
Background: Sperm cryopreservation is an important tool for breed improvement, nonetheless, spermatozoids of rams are extremely sensitive to cryopreservation. Aims: The present research was to compare a liposome-based (OptiXcell: OX) diluent, a commercial TRIS-egg yolk (Optidyl: OP) and a citrate egg yolk-based (CY) diluent on ovine semen quality through the cr...
متن کاملComparison between the conventional and automated systems for frozen cooled equine semen
This study aims to compare the efficiency of the automated system (controlled-rate freezer) and the conventional system (manual system) for freezing the equine semen after cooling at 16C. The parameters evaluated were: motility, strength, plasmatic and acrosomal membrane integrity of spermatozoa from twelve stallions. Ejaculates from stallions were collected three times per week, during four we...
متن کاملComparison between glycerol and ethylene glycol for the cryopreservation of equine spermatozoa: semen quality assessment with standard analyses and with the hypoosmotic swelling test.
The aims of this study were to compare glycerol (G) at customary concentrations and ethylene glycol (EG) as cryoprotectants for stallion semen in a skimmed milk (SM) extender, to test different EG concentrations and to compare the results of manual and computerized analysis with the hypoosmotic swelling (HOS) test. Ejaculates from two stallions were collected over 3 weeks (6 ejaculates per stal...
متن کاملAdvances in Boar Semen Cryopreservation
The present paper highlights aspects of the cryopreservation of boar semen, a species with particular large, fractionated ejaculates, and a cumbersome cryotechnology that had prevented its commercial application. With the dramatic increase of use of liquid pig semen for artificial breeding over the past decade, developments on cryopreservation alongside the routine use of stud boar semen for AI...
