Abstract:
Natural mating deposits a large number of sperm in a high volume of seminal plasma. Semen processed for AI has the seminal plasma greatly diluted, and processing of boar sperm for cryopreservation removes all seminal plasma. Boar sperm were evaluated for the impact of seminal plasma on the functional status of boar sperm. Seminal plasma prevented or reversed capacitation in frozen-thawed boar sperm. However, supplementing frozen-thawed semen doses with 10% seminal plasma did not significantly affect the number of sperm found in the utero-tubal sperm reservoir, nor did it affect farrowing rates.
