This study was conducted to determine effects of seminal plasma components on maintaining motility and acrosomal integrity in Meishan boar spermatozoa during cooling treatments. Ejaculates were collected from a Meishan boar by a manual method. Seminal plasma components were separated by dialysis and anion-exchange column chromatography. Spermatozoa resuspended in TCG solution containing seminal plasma or its components were cooled slowly to 4°C, or rapidly to 0°C, after which sperm motility and acrosomal integrity were examined. For those samples that were cooled slowly, the addition of seminal plasma (5-20%, v/v) exerted protective effects on maintaining sperm motility, but most spermatozoa were immobile at a high concentration (80%). However, the deleterious effects on sperm motility were not detected in seminal plasma dialyzed against TCG solution. When seminal plasma components were separated into four fractions (Fractions 1-4) by anion-exchange column chromatography, the protective effects were detected in Fractions 2 and 4. However, seminal plasma and its components hardly affected acrosomal integrity in the spermatozoa that were cooled slowly. For sperm samples that were cooled rapidly, the protective effects on acrosomal integrity as well as on sperm motility were observed in Fractions 2 and 4. These results imply that Meishan boar seminal plasma contains both beneficial and detrimental components for maintaining sperm motility during the cooling treatments. The formers are characterized by the affinity to the anion-exchange column, i.e., molecules with isoelectric points in acidic and/or neutral ranges, and the latters are passable through the dialysis tubing, i.e., low-molecular-mass molecules.
