Experimental study evaluates post-thaw sperm motility in cryopreserved boar semen treated with sow follicular fluid, indicating potential benefits for artificial insemination techniques.
Boar spermatozoa in volumes of 0.1 ml, 2 ml and 5 ml were pellet-frozen on solid carbon dioxide, and, in volumes of 2 ml, 5 ml and 10 ml were frozen in form of cylinders in evaporation of liquid nitrogen. After 1-6 months of storage, follicular fluid from sow ovaria was added to a part of thawed ejaculates, and, motility of spermatozoa kept at 38.5 C was evaluated. Motility of spermatozoa frozen in 10 ml was
