Abstract

The aim of this study was to investigate the effect of different percentage of seminal plasma proteins with different molecular weight on sperm motility and fertility parameters (farrowing rate (FR), number of live-born pigs (PBA) per litter and percentage of unsuccessful insemination). A total of 50 sperm-rich ejaculate fractions were collected (one per boar) using the gloved hand method. The quality parameters of the semen samples were first evaluated at the farm. Further assessment of sperm quality was performed on a CASA - computer assisted semen analysis by two competent operators. Seminal plasma protein fractions were obtained by AOAC - Association of Official Analytical Chemists as a chemical method. The assessment of reproductive performance was carried out based on collected data of three parameters in selected 9696 sows: FR, PBA per litter and percentage of unsuccessful insemination. Protein fractions were divided in to three groups (10 – 20kDa, 21 – 30kDa and 31 – 40kDa) Proteins with 10 – 20kDa did not have significant effect and correlation with analyzed parameters. Significant differences were recorded in farrowing rate between samples with up to 80 % compared to samples with 10% of proteins with 21 – 30kDa. Significant differences were recorded in unsuccessful insemination between samples with different percentage of proteins with 31 – 40kDa. Results of this study have shown the effect of different percentage of certain fraction of seminal plasma proteins on boar ejaculates fertility potential.
