Abstract
Disclosed are compositions for mammalian, avian or piscian reproductive cells and methods for the collection, holding, processing, in vitro fertilization, sexing culturing, or storing (including long-term cryopreservation) of mammalian or avian reproductive sperm cells. The compositions comprise suitable reproductive cell media and antioxidant bioflavonoids. These may be comprised of Oligomeric Proanthocyanidins (OPC) which include the specific molecules of OPCs, that are namely; (epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG)).
Claims10
A biological culture medium useful for animal reproduction comprising:
- a semen culture medium including,
- a) a semen sample;
- and
- b) a volume of media having multiple dried components that are blended together and diluted before being combined with the semen sample, at least one of the multiple dried components being an oligomeric proanthocyanidin (OPC),
- wherein the OPC mitigates degradation of the semen sample without detrimentally affecting a motility value of the semen sample when used in the semen culture medium, and wherein the semen culture medium is stored at a cooled temperature defined within a range of storage temperatures that prevents freezing of the semen culture medium.
2-9. (canceled)
12-21. (canceled)
A method of preparing a volume of extended porcine boar semen, for non-frozen temporary storage, comprising:
- a) providing a powdered media having,
- i) a first powdered component;
- and
- ii) a second powdered component blended, wherein at least one of the first and second powdered components is an oligomeric proanthocyanidin (OPC);
- b) blending the first and second powdered components with each other;
- c) creating a solution by diluting the blended first and second powdered components with purified water;
- d) adding a collected sample of porcine boar semen to the solution, promptly after collection thereof;
- and
- e) equilibrating the combined sample and solution and defining a volume of extended porcine boar semen,
- wherein the OPC mitigates degradation of the semen sample without detrimentally affecting a motility value of the semen sample and wherein the solution has a pH value of less than about 7.5 and an osmolarity of less than about 350 mOsm.
